                              ABOUT THIS PROSPECTUS

         In this prospectus and in any prospectus supplement, unless otherwise
specified or the context otherwise requires, all dollar amounts are expressed in
United States dollars, references to "dollars", "$" or "US$" are to United
States dollars and all references to "C$" are to Canadian dollars. Unless
otherwise indicated, all financial information included and incorporated by
reference in this prospectus or included in any prospectus supplement is
determined using Canadian generally accepted accounting principles, referred to
as "Canadian GAAP". "U.S. GAAP" means generally accepted accounting principles
in the United States. Except as set forth under "Description of Debt
Securities", and unless the context otherwise requires, all references in this
prospectus and any prospectus supplement to "EnCana", "we", "us" and "our" mean
EnCana Corporation and its consolidated subsidiaries and partnerships.

         This prospectus is part of a registration statement on Form F-9
relating to the debt securities that we filed with the U.S. Securities and
Exchange Commission (the "SEC"). We may, from time to time, sell any combination
of the debt securities described in this prospectus in one or more offerings up
to an aggregate principal amount of US$2,000,000,000. This prospectus provides
you with a general description of the debt securities that we may offer. Each
time we sell debt securities under the registration statement, we will provide a
prospectus supplement that will contain specific information about the terms of
that offering of debt securities. The prospectus supplement may also add, update
or change information contained in this prospectus. Before you invest, you
should read both this prospectus and any applicable prospectus supplement
together with additional information described under the heading "Where You Can
Find More Information". THIS PROSPECTUS DOES NOT CONTAIN ALL OF THE INFORMATION
SET FORTH IN THE REGISTRATION STATEMENT, CERTAIN PARTS OF WHICH ARE OMITTED IN
ACCORDANCE WITH THE RULES AND REGULATIONS OF THE SEC. YOU MAY REFER TO THE
REGISTRATION STATEMENT AND THE EXHIBITS TO THE REGISTRATION STATEMENT FOR
FURTHER INFORMATION WITH RESPECT TO US AND THE DEBT SECURITIES.

         We file with the securities commission or authority in each of the
provinces and territories of Canada, annual and quarterly reports, material
change reports and other information. We are subject to the informational
requirements of the United States Securities Exchange Act of 1934, as amended
(the "Exchange Act") and, in accordance with the Exchange Act, we also file
reports with and furnish other information to the SEC. Under a multijuris-
dictional disclosure system adopted by the United States, these reports and
other information (including financial information) may be prepared in
accordance with the disclosure requirements of Canada, which differ from those
in the United States. You may read any document we furnish to the SEC at the
SEC's public reference rooms at Room 1024, 450 Fifth Street, N.W., Washington,
D.C. 20549. You may also obtain copies of the same documents from the public
reference room of the SEC at 450 Fifth Street, N.W., Washington D.C. 20549 by
paying a fee. Please call the SEC at 1-800-SEC-0330 or contact them at
www.sec.gov for further information on the public reference rooms. Our filings
since November 2002 are also electronically available from the SEC's Electronic
Document Gathering and Retrieval System, which is commonly known by the acronym
EDGAR and which may be accessed at www.sec.gov, as well as from commercial
document retrieval services.

         Under applicable securities laws in Canada and the United States, the
Canadian securities commissions and the SEC allow us to incorporate by reference
certain information that we file with them, which means that we can disclose
important information to you by referring you to those documents. Information

                           FORWARD-LOOKING STATEMENTS

         Certain statements included in this prospectus and the documents
incorporated by reference herein constitute forward-looking statements within
the meaning of the United States Private Securities Litigation Reform Act of
1995 relating to, but not limited to, our operations, anticipated financial
performance, business prospects and strategies. Forward-looking statements
typically contain statements with words such as "anticipate", "believe",
"expect", "plan", "intend" or similar words suggesting future outcomes or
statements regarding an outlook on oil and gas prices, estimates of future
production, reserves and resources, the estimated amounts and timing of capital
expenditures, anticipated future debt levels and royalty rates, or other
expenditures, beliefs, plans, objectives, assumptions or statements about future
events or performance.

         You are cautioned not to place undue reliance on forward-looking
statements. By their nature, forward-looking statements involve numerous
assumptions, inherent risks and uncertainties, both general and specific, that
contribute to the possibility that the predicted outcomes will not occur. These
factors include, but are not limited to:

         o        general economic, business and market conditions;

         o        volatility of crude oil, natural gas and natural gas liquids
                  prices;

         o        fluctuations in currency and interest rates, product supply
                  and demand;

         o        competition;

         o        risks inherent in foreign operations, including political and
                  economic risk;

         o        risks of war, hostilities, civil insurrection and terrorist
                  threats;

         o        risks inherent in marketing operations including credit risks;

         o        imprecision of reserve estimates;

         o        our ability to replace or expand reserves;

         o        our ability to either generate sufficient cash flow to meet
                  current and future obligations or to obtain external debt or
                  equity financing;

         o        our ability to enter into or renew leases;

         o        the timing and costs of pipeline and natural gas storage
                  facility construction and expansion;

         o        our ability to make capital investments and the amounts
                  thereof;

         o        imprecision in estimating future production capacity, and the
                  timing, costs and levels of production and drilling;

         o        results of our exploration, development and drilling activity;

         o        our ability to secure adequate product transportation;

         o        changes in regulations, including environmental regulations;

         o        risks associated with existing and potential future lawsuits
                  and regulatory actions against EnCana;

         o        uncertainty in amounts and timing of royalty payments; and

         o        imprecision in estimating product sales.

         We caution that the foregoing list of important factors is not
exhaustive. Events or circumstances could cause our actual results to differ
materially from those estimated or projected and expressed in, or implied by,
these forward-looking statements. You should also carefully consider the matters
discussed under "Risk Factors" in this prospectus. We undertake no obligation to
update publicly or otherwise revise any forward-looking statements, whether as a

                               ENCANA CORPORATION

         We are one of the world's leading independent crude oil and natural gas
exploration and production companies based on landholdings and production at
December 31, 2003. Our key landholdings are in Western Canada, the U.S. Rocky
Mountains, Ecuador, the United Kingdom ("U.K."), offshore Canada's East Coast
and the Gulf of Mexico. We explore for, produce and market natural gas, crude
oil and natural gas liquids ("NGLs") in Canada and the United States. We are
engaged in exploration and production activities internationally including
production from Ecuador and the U.K. We have interests in midstream operations
and assets, including natural gas storage, NGLs gathering and processing
facilities, power plants and pipelines.

         We continually pursue opportunities to develop and expand our business,
which may include significant corporate or asset acquisitions or dispositions.
We may finance acquisitions with debt or equity, or a combination of both.

         EnCana was formed through the business combination (the "Merger") of
PanCanadian and AEC on April 5, 2002. Pursuant to the Merger, PanCanadian
indirectly acquired all of the outstanding common shares of AEC and
PanCanadian's name was changed to EnCana Corporation. Effective January 1, 2003,
EnCana Corporation amalgamated with its wholly-owned subsidiary, AEC, and
continued as one entity. As a result of the amalgamation, EnCana Corporation is
the successor issuer in respect of AEC's previously issued debt securities and
is responsible for all of AEC's contractual obligations.

         Our principal executive and registered offices are located at 1800, 855
- 2nd Street S.W., Calgary, Alberta T2P 2S5, Canada.

                                 USE OF PROCEEDS

         Unless otherwise indicated in the applicable prospectus supplement
relating to a series of debt securities, we will use the net proceeds we receive
from the sale of the debt securities for general corporate purposes relating to
our primary areas of operations in Western Canada, the U.S. Rocky Mountains,
Ecuador, the U.K., offshore Canada's East Coast, and the Gulf of Mexico. Those
general corporate purposes may include capital expenditures, the repayment of
indebtedness and the financing of acquisitions. The amount of net proceeds to be
used for any such purpose will be described in an applicable prospectus
supplement. We may invest funds that we do not immediately use in short-term
marketable securities.

                         DESCRIPTION OF DEBT SECURITIES

         In this section only, "we", "us", "our" or "EnCana" refer only to
EnCana Corporation without any of its subsidiaries or partnerships through which
it operates. The following description describes certain general terms and
provisions of the debt securities. We will provide the particular terms and
provisions of a series of debt securities and a description of how the general
terms and provisions described below may apply to that series in a supplement to
this prospectus.

         The debt securities will be issued under an indenture (hereinafter
referred to as the "Indenture") to be entered into between us and The Bank of
New York, as "Trustee". The Indenture will be subject to and governed by the
U.S. Trust Indenture Act of 1939, as amended. A copy of the form of Indenture
has been filed as an exhibit to the registration statement filed with the SEC.
The following is a summary of the Indenture which describes certain general
terms and provisions of the debt securities and is not intended to be complete.
Statements in this summary are qualified in their entirety by, and subject to,
the provisions of the Indenture, including the definition of capitalized terms
used under this caption. We urge you to read the Indenture carefully, because it
is the Indenture, and not this summary, that governs your rights as a holder of
our debt securities. Prospective investors should rely


                                       6


on information in the applicable prospectus supplement, which may provide
information that is different from this prospectus.

         We may, from time to time, issue debt instruments and incur additional
indebtedness other than through the issuance of debt securities pursuant to this
prospectus.

GENERAL

         The Indenture does not limit the aggregate principal amount of debt
securities (which may include debentures, notes and other unsecured evidences of
indebtedness) that we may issue under the Indenture. It provides that debt
securities may be issued from time to time in one or more series and may be
denominated and payable in U.S. dollars or any foreign currency. Special
Canadian and U.S. federal income tax considerations applicable to any of our
debt securities denominated in a foreign currency will be described in the
prospectus supplement relating to any offering of debt securities denominated in
a foreign currency. The debt securities offered pursuant to this prospectus will
be issued in an aggregate principal amount of up to US$2,000,000,000, or if any
debt securities are offered at original issue discount, such greater amount as
shall result in an aggregate offering price of up to US$2,000,000,000, or the
equivalent in other currencies. The Indenture also permits us to increase the
principal amount of any series of our debt securities previously issued and to
issue that increased principal amount.

         The applicable prospectus supplement will set forth the specific terms
of a series of debt securities being offered by us and may include the
following:

         o        the specific designation and the aggregate principal amount of
                  the debt securities of such series;

         o        the extent and manner, if any, to which payment on or in
                  respect of our debt securities of such series will be senior

                  liabilities and obligations;

         o        the date or dates on which the principal of (and premium, if
                  any, on) our debt securities of such series will be payable
                  and the portion (if less than the principal amount) of the
                  debt securities of such series to be payable upon a
                  declaration of acceleration of maturity and/or the method by
                  which such date or dates shall be determined or extended;

         o        the rate or rates (whether fixed or variable) at which our
                  debt securities of such series will bear interest, if any, and

         o        the dates on which any interest will be payable and the

                  any, and interest, if any, on) our debt securities will be
                  payable, and each office or agency where our debt securities
                  of such series may be presented for registration of transfer
                  or exchange;

         o        if other than U.S. dollars, the currency in which our debt
                  securities of such series are denominated or in which currency
                  payment of the principal of (and premium, if any, and
                  interest, if any, on) such debt securities of such series will
                  be payable;

         o        whether our debt securities of such series will be issuable in
                  the form of one or more global securities and, if so, the
                  identity of the depositary for the global securities;

                                       7


         o        the terms and conditions, if any, upon which you may redeem
                  our debt securities of such series prior to maturity and the
                  price or prices at which and the currency in which our debt
                  securities of such series are payable;

         o        any index used to determine the amount of payments of
                  principal of (and premium, if any, or interest, if any, on)
                  our debt securities of such series;

         o        the terms, if any, on which our debt securities may be
                  converted or exchanged for other of our securities or
                  securities of other entities;

         o        any other terms of our debt securities of such series,
                  including covenants and events of default which apply solely
                  to a particular series of our debt securities being offered
                  which do not apply generally to other debt securities, or any
                  covenants or events of default generally applicable to our
                  debt securities of such series which do not apply to a
                  particular series of our debt securities;

         o        whether and under what circumstances we will pay Additional
                  Amounts (defined below under "Payment of Additional Amounts")
                  on the debt securities of such series in respect of certain
                  taxes (and the terms of any such payment) and, if so, whether
                  we will have the option to redeem the debt securities of such
                  series rather than pay the Additional Amounts (and the terms
                  of any such option);

         o        whether the payment of our debt securities will be guaranteed
                  by any other person;

         o        whether the series of our debt securities are to be registered
                  securities, bearer securities (with or without coupons) or
                  both;

         o        if other than denominations of US$1,000 and any integral
                  multiple thereof, the denominations in which any registered

                  the denomination of US$5,000, the denomination or
                  denominations in which any bearer securities of the series
                  shall be issuable; and

                  limitations on such rights and preferences) of the debt
                  securities of such series.

         Unless otherwise indicated in the applicable prospectus supplement, the
Indenture does not afford holders of our debt securities the right to tender
such debt securities to us in the event that we have a change in control.

         Our debt securities may be issued under the Indenture bearing no
interest or at a discount below their stated principal amount. The Canadian and
U.S. federal income tax consequences and other special considerations applicable
to any such discounted debt securities or other debt securities offered and sold
at par which are treated as having been issued at a discount for Canadian and/or
U.S. federal income tax purposes will be described in the prospectus supplement
relating to the debt securities.

RANKING AND OTHER INDEBTEDNESS

         Unless otherwise indicated in an applicable prospectus supplement, the
debt securities will be unsecured obligations and will rank equally with all of
our other unsecured and unsubordinated indebtedness outstanding from time to
time. The debt securities will be structurally subordinated to all existing and
future indebtedness and liabilities of any of our subsidiaries or partnerships.

FORM, DENOMINATIONS AND EXCHANGE

         A series of our debt securities may be issued solely as registered
securities, solely as bearer securities or as both registered securities and
bearer securities. The Indenture also provides that a series of our debt
securities may be issuable in global form. Registered securities will be
issuable in denominations of US$1,000 and integral multiples of US$1,000 and
bearer securities will be issuable in


                                       8


denominations of US$5,000 or, in each case, in such other denominations as may
be set out in the terms of the debt securities of any particular series. Unless
otherwise indicated in the applicable prospectus supplement, bearer securities
will have interest coupons attached.

         A prospectus supplement may indicate the places to register a transfer
of our debt securities. Except for certain restrictions set forth in the
Indenture, no service charge will be made for any registration of transfer or
exchange of our debt securities, but we may, in certain instances, require a sum
sufficient to cover any tax or other governmental charges payable in connection
with these transactions.

         We shall not be required to:

         o        issue, register the transfer of or exchange any series of our
                  debt securities during a period beginning at the opening of
                  business 15 days before any selection of that series of our
                  debt securities to be redeemed and ending at the close of
                  business on (i) if the series of our debt securities are
                  issuable only as registered securities, the day of mailing of
                  the relevant notice of redemption and (ii) if the series of
                  our debt securities are issuable as bearer securities, the day
                  of the first publication of the relevant notice of redemption
                  or, if the series of our debt securities are also issuable as
                  registered securities and there is no publication, the mailing
                  of the relevant notice of redemption;

         o        register the transfer of or exchange any registered security,
                  or portion thereof, called for redemption, except the
                  unredeemed portion of any registered security being redeemed
                  in part;

         o        exchange any bearer security selected for redemption, except
                  that, to the extent provided with respect to such bearer
                  security, such bearer security may be exchanged for a
                  registered security of that series and like tenor, PROVIDED
                  that such registered security shall be immediately surrendered
                  for redemption with written instruction for payment consistent
                  with the provisions of the Indenture; or

         o        issue, register the transfer of or exchange any of our debt
                  securities which have been surrendered for repayment at the
                  option of the holder, except the portion, if any, thereof not
                  to be so repaid.

PAYMENT

         Unless otherwise indicated in the applicable prospectus supplement,
payment of principal of, (and premium, if any, and interest, if any, on) our
debt securities (other than global securities) will be made at the office or
agency of the Trustee, at 101 Barclay Street, 21st Floor West, New York, New
York 10286.

         Unless otherwise indicated in the applicable prospectus supplement,
payment of any interest will be made to the persons in whose name our debt
securities are registered at the close of business on the day or days specified
by us.

GLOBAL SECURITIES

         A series of our debt securities may be issued in whole or in part in
global form as a "global security" and will be registered in the name of and be
deposited with a depositary, or its nominee, each of which will be identified in
the prospectus supplement relating to that series. Unless and until exchanged,
in whole or in part, for our debt securities in definitive registered form, a
global security, may not be transferred except as a whole by the depositary for
such global security to a nominee of the depositary, by a nominee of the
depositary to the depositary or another nominee of the depositary or by the
depositary or any such nominee to a successor of the depositary or a nominee of
the successor.


                                       9


         The specific terms of the depositary arrangement with respect to any
portion of a particular series of our debt securities to be represented by a
global security will be described in a prospectus supplement relating to such
series. We anticipate that the following provisions will apply to all depositary
arrangements.

         Upon the issuance of a global security, the depositary therefor or its
nominee will credit, on its book entry and registration system, the respective
principal amounts of our debt securities represented by the global security to
the accounts of such persons, designated as "participants", having accounts with
such depositary or its nominee. Such accounts shall be designated by the
underwriters, dealers or agents participating in the distribution of our debt
securities or by us if such debt securities are offered and sold directly by us.
Ownership of beneficial interests in a global security will be limited to
participants or persons that may hold beneficial interests through participants.
Ownership of beneficial interests in a global security will be shown on, and the
transfer of that ownership will be effected only through, records maintained by
the depositary therefor or its nominee (with respect to interests of
participants) or by participants or persons that hold through participants (with
respect to interests of persons other than participants). The laws of some
states in the United States require that certain purchasers of securities have
the ability to take physical delivery of such debt securities in definitive
form.

         So long as the depositary for a global security, or its nominee, is the
registered owner of the global security, such depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the debt securities
represented by the global security for all purposes under the Indenture. Except
as provided below, owners of beneficial interests in a global security will not
be entitled to have a series of our debt securities represented by the global
security registered in their names, will not receive or be entitled to receive
physical delivery of such series of our debt securities in definitive form and
will not be considered the owners or holders thereof under the Indenture.

         Any payments of principal, premium, if any, and interest on global
securities registered in the name of a depositary or its nominee will be made to
the depositary or its nominee, as the case may be, as the registered owner of
the global security representing such debt securities. Neither we, the Trustee
nor any paying agent for our debt securities represented by the global
securities will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the global security or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

         We expect that the depositary for a global security or its nominee,
upon receipt of any payment of principal, premium, if any, or interest, will
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the global security
as shown on the records of such depositary or its nominee. We also expect that
payments by participants to owners of beneficial interests in a global security
held through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers registered in "street name", and will be the responsibility of such
participants.

         If a depositary for a global security representing a particular series
of our debt securities is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by us within 90 days, we
will issue such series of our debt securities in definitive form in exchange for
a global security representing such series of our debt securities. In addition,
we may at any time and in our sole discretion determine not to have a series of
our debt securities represented by a global security and, in such event, will
issue a series of our debt securities in definitive form in exchange for all of
the global securities representing the series of debt securities.

indebtedness is limited in all circumstances to the properties or assets
created, developed, constructed or acquired in respect of which such
indebtedness has been incurred and to the receivables, inventory, equipment,
chattels payable, contracts, intangibles and other assets, rights or collateral
connected with the properties or assets created, developed, constructed or

COVENANTS

LIMITATION ON LIENS

         The Indenture provides that so long as any of our debt securities are
outstanding and subject to the provisions of the Indenture, we will not, and
will not permit any of our Restricted Subsidiaries to, create, incur, assume or
otherwise have outstanding any Lien securing any indebtedness for borrowed money
or interest thereon (or any liability of ours or such Restricted Subsidiaries
under any guarantee or endorsement or other instrument under which we or such
Restricted Subsidiaries are contingently liable, either directly or indirectly,
for borrowed money or interest thereon), other than Permitted Liens, without
also simultaneously or prior thereto securing, or causing such Restricted
Subsidiaries to secure, indebtedness under the Indenture so that our debt
securities are secured equally and rateably with or prior to such other
indebtedness, except that we and our Restricted Subsidiaries may incur a


                                       14


Lien to secure indebtedness for borrowed money without securing our debt
securities if, after giving effect thereto, the principal amount of indebtedness
for borrowed money secured by Liens created, incurred or assumed after the date
of the Indenture and otherwise prohibited by the Indenture does not exceed 10%
of our Consolidated Net Tangible Assets.

         Notwithstanding the foregoing, transactions such as the sale (including
any forward sale) or other transfer of (i) oil, gas, minerals or other resources
of a primary nature, whether in place or when produced, for a period of time
until, or in an amount such that, the purchaser will realize therefrom a
specified amount of money or a specified rate of return (however determined), or
a specified amount of such oil, gas, minerals, or other resources of a primary
nature, or (ii) any other interest in property of the character commonly
referred to as a "production payment", will not constitute a Lien and will not
result in us or a Restricted Subsidiary of ours being required to secure the
debt securities.

CONSOLIDATION, AMALGAMATION, MERGER AND SALE OF ASSETS

         We may not consolidate or amalgamate with or merge into or enter into
any statutory arrangement with any other corporation, or convey, transfer or
lease all or substantially all our properties and assets to any person, unless:

         o        the entity formed by or continuing from such consolidation or
                  amalgamation or into which we are merged or with which we
                  enter into such statutory arrangement or the person which
                  acquires or leases all or substantially all of our properties
                  and assets is organized and existing under the laws of the
                  United States, any state thereof or the District of Columbia
                  or the laws of Canada or any province or territory thereof,
                  or, if such consolidation, amalgamation, merger, statutory
                  arrangement or other transaction would not impair the rights
                  of the holders of our debt securities, in any other country,
                  PROVIDED that if such successor entity is organized under the
                  laws of a jurisdiction other than the United States, any state
                  thereof or the District of Columbia, or the laws of Canada or
                  any province or territory thereof, the successor entity
                  assumes our obligations under the debt securities and the
                  Indenture to pay Additional Amounts, including the name of
                  such successor jurisdiction in addition to Canada in each
                  place that Canada appears in "-- Payment of Additional
                  Amounts" below;

         o        the successor entity expressly assumes or assumes by operation
                  of law all of our obligations under our debt securities and
                  under the Indenture;

         o        immediately before and after giving effect to such
                  transaction, no event of default, and no event which, after
                  notice or lapse of time or both, would become an event of
                  default, shall have happened and be continuing; and

         o        certain other conditions are met.

         If, as a result of any such transaction, any of our Restricted
Properties become subject to a Lien, then, unless such Lien could be created
pursuant to the Indenture provisions described under the "LIMITATION ON LIENS"
covenant above without equally and rateably securing our debt securities, we,
simultaneously with or prior to such transaction, will cause our debt securities
to be secured equally and rateably with or prior to the indebtedness secured by
such Lien.

PAYMENT OF ADDITIONAL AMOUNTS

         Unless otherwise specified in the applicable prospectus supplement, all
payments made by or on behalf of us under or with respect to any series of our
debt securities will be made free and clear of and without withholding or
deduction for or on account of any present or future tax, duty, levy, impost,
assessment or other governmental charge (including penalties, interest and other
liabilities related thereto) imposed or levied by or on behalf of the Government
of Canada or any province or territory thereof or by any authority or agency
therein or thereof having power to tax (hereinafter "Canadian


                                       15


Taxes"), unless we are required to withhold or deduct Canadian Taxes by law or
by the interpretation or administration thereof. If we are so required to
withhold or deduct any amount for or on account of Canadian Taxes from any
payment made under or with respect to the debt securities, we will pay to each
holder of such debt securities as additional interest such additional amounts
("Additional Amounts") as may be necessary so that the net amount received by
each such holder after such withholding or deduction (and after deducting any
Canadian Taxes on such Additional Amounts) will not be less than the amount such
holder would have received if such Canadian Taxes had not been withheld or
deducted. However, no Additional Amounts will be payable with respect to a
payment made to a debt securities holder (such holder, an "Excluded Holder") in
respect of the beneficial owner thereof:

         o        with which we do not deal at arm's length (for the purposes of
                  the INCOME TAX ACT (Canada)) at the time of the making of such
                  payment;

         o        which is subject to such Canadian Taxes by reason of the debt
                  securities holder being a resident, domicile or national of,
                  or engaged in business or maintaining a permanent
                  establishment or other physical presence in or otherwise
                  having some connection with Canada or any province or
                  territory thereof otherwise than by the mere holding of the
                  debt securities or the receipt of payments thereunder; or

         o        which is subject to such Canadian Taxes by reason of the debt
                  securities holder's failure to comply with any certification,
                  identification, documentation or other reporting requirements
                  if compliance is required by law, regulation, administrative
                  practice or an applicable treaty as a precondition to
                  exemption from, or a reduction in the rate of deduction or
                  withholding of, such Canadian Taxes.

         We will also:

         o        make such withholding or deduction; and

         o        remit the full amount deducted or withheld to the relevant
                  authority in accordance with applicable law.

         We will furnish to the holders of the debt securities, within 60 days
after the date the payment of any Canadian Taxes is due pursuant to applicable
law, certified copies of tax receipts or other documents evidencing such payment
by us.

         We will indemnify and hold harmless each holder of debt securities
(other than an Excluded Holder) and upon written request reimburse each such
holder for the amount (excluding any Additional Amounts that have previously
been paid by us with respect thereto) of:

         o        the payment of any Canadian Tax, together with any interest,
                  penalties and reasonable expenses in connection therewith; and

         o        any Canadian Taxes imposed with respect to any reimbursement
                  under the preceding clause, but excluding any such Canadian
                  Taxes on such holder's net income.

         In any event, no Additional Amounts or indemnity amounts will be
payable in excess of Additional Amounts or the indemnity amounts which would be
required if the holder of debt securities was a resident of the United States
for purposes of the Canada-United States Tax Convention (1980), as amended.

         Wherever in the Indenture there is mentioned, in any context, the
payment of principal (and premium, if any), interest, if any, or any other
amount payable under or with respect to a debt security, such mention shall be
deemed to include mention of the payment of Additional Amounts to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof.


                                       16


TAX REDEMPTION

         Unless otherwise specified in the applicable prospectus supplement, a
series of our debt securities will be subject to redemption at any time, in
whole but not in part, at a redemption price equal to the principal amount
thereof together with accrued and unpaid interest to the date fixed for
redemption, upon the giving of a notice as described below, if:

         o        as a result of any change in or amendment to the laws (or any
                  regulations or rulings promulgated thereunder) of Canada or of
                  any political subdivision or taxing authority thereof or
                  therein affecting taxation, or any change in official position
                  regarding the application or interpretation of such laws,
                  regulations or rulings (including a holding by a court of
                  competent jurisdiction), which change or amendment is
                  announced or becomes effective on or after the date specified
                  in the applicable prospectus supplement, we have or will
                  become obligated to pay, on the next succeeding date on which
                  interest is due, Additional Amounts or indemnity amounts with
                  respect to any debt security of such series as described under
                  "-- Payment of Additional Amounts"; or

         o        on or after the date specified in the applicable prospectus
                  supplement, any action has been taken by any taxing authority
                  of, or any decision has been rendered by a court of competent
                  jurisdiction in Canada, or any political subdivision or taxing
                  authority thereof or therein, including any of those actions
                  specified in the paragraph immediately above, whether or not
                  such action was taken or decision was rendered with respect to
                  us, or any change, amendment, application or interpretation
                  shall be officially proposed, which, in any such case, in the
                  written opinion to us of legal counsel of recognized standing,
                  will result in our becoming obligated to pay, on the next
                  succeeding date on which interest is due, Additional Amounts
                  or indemnity amounts with respect to any debt security of such
                  series as described under "-- Payment of Additional Amounts";

and, in any such case, we, in our business judgment, determine that such
obligation cannot be avoided by the use of reasonable measures available to us.

         In the event that we elect to redeem a series of our debt securities
pursuant to the provisions set forth in the preceding paragraph, we shall
deliver to the Trustee a certificate, signed by an authorized officer, stating
that we are entitled to redeem such series of our debt securities pursuant to
their terms.

         Notice of intention to redeem such series of our debt securities will
be given not more than 60 nor less than 30 days prior to the date fixed for
redemption and will specify the date fixed for redemption.

PROVISION OF FINANCIAL INFORMATION

         We will file with the Trustee, within 15 days after we file them with
or furnish them to the SEC, copies, which may be in electronic format, of our
annual report and of the information, documents and other reports (or copies of
such portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which we are required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act.

         Notwithstanding that we may not be required to remain subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise
report on an annual and quarterly basis on forms provided for such annual and
quarterly reporting pursuant to rules and regulations promulgated by the SEC, we
will continue to provide the Trustee:

         o        within 140 days after the end of each fiscal year, the
                  information required to be contained in annual reports on Form
                  20-F, Form 40-F or Form 10-K as applicable (or any successor
                  form); and


                                       17

                  quarters of each fiscal year, the information required to be
                  contained in reports on Form 6-K (or any successor form)
                  which, regardless of applicable requirements shall, at a
                  minimum, contain such information required to be provided in
                  quarterly reports under the laws of Canada or any province
                  thereof to security holders of a corporation with securities
                  listed on the Toronto Stock Exchange, whether or not we have
                  any of our securities listed on such exchange. Such
                  information will be prepared in accordance with Canadian
                  disclosure requirements and GAAP; PROVIDED, HOWEVER, that we
                  shall not be obligated to file such report with the SEC if the
                  SEC does not permit such filings.

EVENTS OF DEFAULT

         The following are summaries of events of default under the Indenture
with respect to any series of our debt securities:

         o        default in the payment of any interest on any debt security of
                  that series when it becomes due and payable, and continuance
                  of such default for a period of 30 days;

         o        default in the payment of the principal of (or premium, if
                  any, on), any debt security of that series when it becomes due
                  and payable;

         o        default in the performance, or breach, of any of our covenants
                  or warranties in the Indenture in respect of our debt
                  securities of that series (other than a covenant or warranty a
                  default in the performance of which or the breach of which is
                  specifically dealt with elsewhere in the Indenture), and
                  continuance of such default or breach for a period of 60 days
                  after receipt by us of written notice to us, specifying such
                  default or breach, by the Trustee or by the holders of at
                  least 25% in principal amount of all outstanding debt
                  securities of any series affected thereby;

         o        if an event of default (as defined in any indenture or
                  instrument under which we or one of our Restricted
                  Subsidiaries has at the time of the Indenture or shall
                  thereafter have outstanding any indebtedness for borrowed
                  money) shall happen and be continuing, or EnCana or any
                  Restricted Subsidiary shall have failed to pay principal
                  amounts with respect to such indebtedness at maturity and such
                  event of default or failure to pay shall result in such
                  indebtedness being declared due and payable or otherwise being
                  accelerated, in either event so that an amount in excess of
                  the greater of US$75,000,000 and 2% of our Shareholders'
                  Equity shall be or become due and payable upon such
                  declaration or otherwise accelerated prior to the date on
                  which the same would otherwise have become due and payable
                  (the "accelerated indebtedness"), and such acceleration shall
                  not be rescinded or annulled, or such event of default or
                  failure to pay under such indenture or instrument shall not be
                  remedied or cured, whether by payment or otherwise, or waived
                  by the holders of such accelerated indebtedness, then (i) if
                  the accelerated indebtedness shall be as a result of an event
                  of default which is not related to the failure to pay
                  principal or interest on the terms, at the times, and on the
                  conditions set out in any such indenture or instrument, it
                  shall not be considered an event of default for purposes of
                  the Indenture until 30 days after such indebtedness has been
                  accelerated, or (ii) if the accelerated indebtedness shall
                  occur as a result of such failure to pay principal or interest
                  or as a result of an event of default which is related to the
                  failure to pay principal or interest on the terms, at the
                  times, and on the conditions set out in any such indenture or
                  instrument, then (A) if such accelerated indebtedness is, by
                  its terms, Non-Recourse Debt to us or our Restricted
                  Subsidiaries, it shall not be considered an event of default
                  for purposes of the Indenture; or (B) if such accelerated
                  indebtedness is recourse to us or our Restricted Subsidiaries,
                  any requirement in connection with such failure to pay or
                  event of default for the giving of notice or the lapse of time
                  or the happening of any further condition, event or act under
                  such other indenture or instrument in connection with such
                  failure to pay principal or an event of default


                                       18


                  shall be applicable together with an additional seven days
                  before being considered an event of default for purposes of
                  the Indenture;

         o        certain events in bankruptcy, insolvency or reorganization; or

         o        any other events of default provided with respect to debt
                  securities of that series.

         If an event of default under the Indenture occurs and is continuing
with respect to any series of our debt securities, then and in every such case
the Trustee or the holders of at least 25% in aggregate principal amount of the
outstanding debt securities of such affected series may, subject to any
subordination provisions thereof, declare the entire principal amount (or, if
the debt securities of that series are original issue discount debt securities,
such portion of the principal amount as may be specified in the terms of that
series) of all debt securities of such series and all accrued and unpaid
interest thereon to be immediately due and payable. However, at any time after a
declaration of acceleration with respect to any series of our debt securities
has been made, but before a judgment or decree for payment of the money due has
been obtained, the holders of a majority in principal amount of the outstanding
debt securities of that series, by written notice to us and the Trustee under
certain circumstances, may rescind and annul such acceleration.

         Reference is made to the applicable prospectus supplement or
supplements relating to each series of our debt securities which are original
issue discount debt securities for the particular provisions relating to
acceleration of the maturity of a portion of the principal amount of such
original issue discount securities upon the occurrence of any event of default
and the continuation thereof.

         Subject to certain limitations set forth in the Indenture, the holders
of a majority in principal amount of the outstanding debt securities of all
series affected by an event of default shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, with respect
to the debt securities of all series affected by such event of default.

         No holder of a debt security of any series will have any right to
institute any proceeding with respect to the Indenture, or for the appointment
of a receiver or a trustee, or for any other remedy thereunder, unless:

         o        such holder has previously given to the Trustee written notice
                  of a continuing event of default with respect to the debt
                  securities of such series affected by such event of default;

         o        the holders of at least 25% in aggregate principal amount of
                  the outstanding debt securities of such series (voting as one
                  class) affected by such event of default have made written
                  request, and such holder or holders have offered reasonable
                  indemnity, to the Trustee to institute such proceeding as
                  Trustee; and

         o        the Trustee has failed to institute such proceeding, and has
                  not received from the holders of a majority in aggregate
                  principal amount of the outstanding debt securities of such
                  series affected by such event of default a direction
                  inconsistent with such request, within 60 days after such
                  notice, request and offer.

         However, such above-mentioned limitations do not apply to a suit
instituted by the holder of a debt security for the enforcement of payment of
the principal of or any premium or interest on such debt security on or after
the applicable due date specified in such debt security.

         We will annually furnish to the Trustee a statement by certain of our
officers as to whether or not we, to the best of their knowledge, are in
compliance with all conditions and covenants of the Indenture and, if not,
specifying all such known defaults.


                                       19


DEFEASANCE AND COVENANT DEFEASANCE

         Unless otherwise specified in the applicable prospectus supplement, the
Indenture provides that, at our option, we will be discharged from any and all
obligations in respect of the outstanding debt securities of any series upon
irrevocable deposit with the Trustee, in trust, of money and/or government
securities which will provide money in an amount sufficient in the opinion of a
nationally recognized firm of independent chartered accountants (as evidenced by
an officer's certificate delivered to the Trustee) to pay the principal of (and
premium, if any, and each installment of interest, if any, on) the outstanding
debt securities of such series (hereinafter referred to as a "defeasance")
(except with respect to the authentication, transfer, exchange or replacement of
our debt securities or the maintenance of a place of payment and certain other
obligations set forth in the Indenture). Such trust may only be established if
among other things:

         o        we have delivered to the Trustee an opinion of counsel in the
                  United States stating that (i) we have received from, or there
                  has been published by, the Internal Revenue Service a ruling,
                  or (ii) since the date of execution of the Indenture, there
                  has been a change in the applicable U.S. federal income tax
                  law, in either case to the effect that the holders of the
                  outstanding debt securities of such series will not recognize
                  income, gain or loss for U.S. federal income tax purposes as a
                  result of such defeasance and will be subject to U.S. federal
                  income tax on the same amounts, in the same manner and at the
                  same times as would have been the case if such defeasance had
                  not occurred;

         o        we have delivered to the Trustee an opinion of counsel in
                  Canada or a ruling from the Canada Revenue Agency to the
                  effect that the holders of the outstanding debt securities of
                  such series will not recognize income, gain or loss for
                  Canadian federal or provincial income or other tax purposes as
                  a result of such Defeasance and will be subject to Canadian
                  federal or provincial income and other tax on the same
                  amounts, in the same manner and at the same times as would
                  have been the case had such defeasance not occurred (and for
                  the purposes of such opinion, such Canadian counsel shall
                  assume that holders of the outstanding debt securities of such
                  series include holders who are not resident in Canada);

         o        no event of default or event that, with the passing of time or
                  the giving of notice, or both, shall constitute an event of
                  default shall have occurred and be continuing on the date of
                  such deposit; and

         o        we are not an "insolvent person" within the meaning of the
                  BANKRUPTCY AND INSOLVENCY ACT (Canada) on the date of such
                  deposit or at any time during the period ending on the 91st
                  day following such deposit.

         We may exercise our defeasance option notwithstanding our prior
exercise of our Covenant Defeasance option described in the following paragraph
if we meet the conditions described in the preceding sentence at the time we
exercise the defeasance option.

         The Indenture provides that, at our option, unless and until we have
exercised our Defeasance option described in the preceding paragraph, we may
omit to comply with the "LIMITATION ON LIENS" covenant, certain aspects of the
"CONSOLIDATION, AMALGAMATION, MERGER AND SALE OF ASSETS" covenant and certain
other covenants and such omission shall not be deemed to be an event of default
under the Indenture and our outstanding debt securities upon irrevocable deposit
with the Trustee, in trust, of money and/or government securities which will
provide money in an amount sufficient in the opinion of a nationally recognized
firm of independent chartered accountants (as evidenced by an officer's
certificate delivered to the Trustee) to pay the principal of (and premium, if
any, and each installment of interest, if any, on) the outstanding debt
securities (hereinafter referred to as "covenant defeasance"). If we exercise
our covenant defeasance option, the obligations under the Indenture other than
with respect to such covenants and the events of default other


                                       20


than with respect to such covenants shall remain in full force and effect. Such
trust may only be established if, among other things:

         o        we have delivered to the Trustee an opinion of counsel in the
                  United States to the effect that the holders of our
                  outstanding debt securities will not recognize income, gain or
                  loss for U.S. federal income tax purposes as a result of such
                  covenant defeasance and will be subject to U.S. federal income
                  tax on the same amounts, in the same manner and at the same
                  times as would have been the case if such covenant defeasance
                  had not occurred;

         o        we have delivered to the Trustee an opinion of counsel in
                  Canada or a ruling from the Canada Revenue Agency to the
                  effect that the holders of our outstanding debt securities
                  will not recognize income, gain or loss for Canadian federal
                  or provincial income or other tax purposes as a result of such
                  covenant defeasance and will be subject to Canadian federal or
                  provincial income and other tax on the same amounts, in the
                  same manner and at the same times as would have been the case
                  had such covenant defeasance not occurred (and for the
                  purposes of such opinion, such Canadian counsel shall assume
                  that holders of our outstanding debt securities include
                  holders who are not resident in Canada);

         o        no event of default or event that, with the passing of time or
                  the giving of notice, or both, shall constitute an event of
                  default shall have occurred and be continuing on the date of
                  such deposit; and

         o        we are not an "insolvent person" within the meaning of the
                  BANKRUPTCY AND INSOLVENCY ACT (Canada) on the date of such
                  deposit or at any time during the period ending on the 91st
                  day following such deposit.

MODIFICATION AND WAIVER

         Modifications and amendments of the Indenture may be made by us and the
Trustee with the consent of the holders of a majority in principal amount of the
outstanding debt securities of each series issued under the Indenture affected
by such modification or amendment (voting as one class); PROVIDED, HOWEVER, that
no such modification or amendment may, without the consent of the holder of each
outstanding debt security of such affected series:

         o        change the stated maturity of the principal of, or any
                  installment of interest, if any, on any debt security;

         o        reduce the principal amount of (or premium, if any, or
                  interest, if any, on) any debt security;

         o        reduce the amount of principal of a debt security payable upon
                  acceleration of the maturity thereof;

         o        change the place of payment;

         o        change the currency of payment of principal of (or premium, if
                  any, or interest, if any, on) any debt security;

         o        impair the right to institute suit for the enforcement of any
                  payment on or with respect to any debt security;

         o        reduce the percentage of principal amount of outstanding debt
                  securities of such series, the consent of the holders of which
                  is required for modification or amendment of the applicable
                  Indenture or for waiver of compliance with certain provisions
                  of the Indenture or for waiver of certain defaults; or


                                       21


         o        modify any provisions of the Indenture relating to the
                  modification and amendment of the Indenture or the waiver of
                  past defaults or covenants except as otherwise specified in
                  the Indenture.

         The holders of a majority in principal amount of our outstanding debt
securities of any series may on behalf of the holders of all debt securities of
that series waive, insofar as that series is concerned, compliance by us with
certain restrictive provisions of the Indenture. The holders of a majority in
principal amount of outstanding debt securities of any series may waive any past
default under the Indenture with respect to that series, except a default in the
payment of the principal of (or premium, if any) and interest, if any, on any
debt security of that series or in respect of a provision which under the
Indenture cannot be modified or amended without the consent of the holder of
each outstanding debt security of that series.

         The Indenture or the debt securities may be amended or supplemented,
without the consent of any holder of such debt securities, in order to, among
other things, cure any ambiguity or inconsistency or to make any change, in any
case, that does not have a materially adverse effect on the rights of any holder
of such debt securities.

CONSENT TO JURISDICTION AND SERVICE

         Under the Indenture, we irrevocably appoint CT Corporation System,
111-8th Avenue, 13th Floor, New York, New York, as our authorized agent for
service of process in any suit or proceeding arising out of or relating to our
debt securities or the Indenture and for actions brought under federal or state
securities laws in any federal or state court located in the New York, New York
and irrevocably submit to the non-exclusive jurisdiction of any such court.

GOVERNING LAW

         Our debt securities and the Indenture will be governed by and construed
in accordance with the laws of the State of New York.

ENFORCEABILITY OF JUDGMENTS

         Since most of our assets, as well as the assets of a number of our
directors and officers, are outside the United States, any judgment obtained in
the United States against us or certain of our directors or officers, including
judgments with respect to the payment of principal on any debt securities, may
not be collectible within the United States.

         Because the Trustee is located in the United States, it may not be
possible for purchasers of our debt securities outside the United States to
effect service of process outside the United States upon the Trustee nor to
enforce against the Trustee, outside the United States, judgments obtained in
courts outside the United States. Also it may not be possible to enforce
judgments of non-U.S. courts against the Trustee in the United States.

         We have been advised by Macleod Dixon LLP, our Canadian counsel, that
there is doubt as to the enforceability, in original actions in Canadian courts,
of liabilities based upon the U.S. federal securities laws and as to the
enforceability in Canadian courts of judgments of U.S. courts obtained in
actions based upon the civil liability provisions of the U.S. federal securities
laws. Therefore, it may not be possible to enforce those actions against us, our
directors and officers or the experts named in the prospectus.


                                       22


                                  RISK FACTORS

         You should consider carefully the risk factors set forth below as well
as the other information contained in and incorporated by reference in this
prospectus and in the applicable prospectus supplement before purchasing the
debt securities. Additional risk factors are discussed in our Annual Information
Form which risk factors are incorporated herein by reference. If any event
arising from these risks occurs, our business, prospects, financial condition,
results of operation or cash flows could be materially adversely affected.

A SUBSTANTIAL OR EXTENDED DECLINE IN CRUDE OIL AND NATURAL GAS PRICES COULD HAVE
A MATERIAL ADVERSE EFFECT ON US.

         Our financial condition is substantially dependent on the prevailing
prices of crude oil and natural gas. Fluctuations in crude oil or natural gas
prices could have an adverse effect on our operations and financial condition
and the value and amount of our reserves. Prices for crude oil and natural gas
fluctuate in response to changes in the supply of and demand for, crude oil and
natural gas, market uncertainty and a variety of additional factors beyond our
control. Crude oil prices are determined by international supply and demand.
Factors which affect crude oil prices include the actions of the Organization of
Petroleum Exporting Countries, world economic conditions, government regulation,
political stability in the Middle East and elsewhere, the foreign supply of
crude oil, the price of foreign imports, the availability of alternate fuel
sources and weather conditions. Natural gas prices realized by us are affected
primarily by North American supply and demand, weather conditions and by prices
of alternate sources of energy. Any substantial or extended decline in the
prices of crude oil and natural gas could result in a delay or cancellation of
existing or future drilling, development or construction programs or curtailment
in production at some properties or result in unutilized long-term
transportation commitments, all of which could have an adverse effect on our
revenues, profitability and cash flows.

         We conduct an annual assessment of the carrying value of our assets in
accordance with Canadian GAAP. If crude oil and natural gas prices decline, the
carrying value of our assets could be subject to financial downward revisions,
and our earnings could be adversely affected.

IF WE FAIL TO ACQUIRE OR FIND ADDITIONAL CRUDE OIL AND NATURAL GAS RESERVES, OUR
RESERVES AND PRODUCTION WILL DECLINE MATERIALLY FROM THEIR CURRENT LEVELS.

         Our future crude oil and natural gas reserves and production, and
therefore our cash flows, are highly dependent upon our success in exploiting
our current reserve base and acquiring or discovering additional reserves.
Without reserve additions through exploration, acquisition or development
activities, our reserves and production will decline over time as reserves are
depleted. The business of exploring for, developing or acquiring reserves is
capital intensive. To the extent cash flows from operations are insufficient and
external sources of capital become limited, our ability to make the necessary
capital investments to maintain and expand our crude oil and natural gas
reserves will be impaired. In addition, there can be no guarantee that we will
be able to find and develop or acquire additional reserves to replace production
at acceptable costs.

OUR CRUDE OIL AND NATURAL GAS RESERVE DATA AND FUTURE NET REVENUE ESTIMATES ARE
UNCERTAIN.

         There are numerous uncertainties inherent in estimating quantities of
crude oil and natural gas reserves, including many factors beyond our control.
The reserve data incorporated herein represents estimates only. In general,
estimates of economically recoverable crude oil and natural gas reserves and the
future net cash flows therefrom are based upon a number of variable factors and
assumptions, such as product prices, future operating and capital costs,
historical production from the properties and the assumed effects of regulation
by governmental agencies, all of which may vary considerably from actual


                                       23


results. All such estimates are to some degree uncertain, and classifications of
reserves are only attempts to define the degree of uncertainty involved. For
those reasons, estimates of the economically recoverable crude oil and natural
gas reserves attributable to any particular group of properties, classification
of such reserves based on risk of recovery and estimates of future net revenues
expected therefrom, prepared by different engineers or by the same engineers at
different times, may vary substantially. Our actual production, revenues, taxes
and development and operating expenditures with respect to our reserves may vary
from such estimates, and such variances could be material.

         Estimates with respect to reserves that may be developed and produced
in the future are often based upon volumetric calculations and upon analogy to
similar types of reserves, rather than upon actual production history. Estimates
based on these methods generally are less reliable than those based on actual
production history. Subsequent evaluation of the same reserves based upon
production history will result in variations, which may be material, in the
estimated reserves.

WE WILL NOT OPERATE ALL OF OUR PROPERTIES AND ASSETS.

         Other companies operate some of the assets in which we have interests.
As a result, we will have limited ability to exercise influence over operations
of these assets or their associated costs. Our dependence on the operator and
other working interest owners for these properties and our limited ability to
influence operations and associated costs could materially adversely affect our
financial performance. The success and timing of our activities on assets
operated by others therefore will depend upon a number of factors that are
outside of our control, including:

         o        timing and amount of capital expenditures;

         o        the operator's expertise and financial resources;

         o        approval of other participants;

         o        selection of technology; and

         o        risk management practices.

OUR BUSINESS IS SUBJECT TO ENVIRONMENTAL LEGISLATION IN ALL JURISDICTIONS IN
WHICH WE OPERATE AND ANY CHANGES IN SUCH LEGISLATION COULD NEGATIVELY AFFECT OUR
RESULTS OF OPERATIONS.

         All phases of the crude oil and natural gas business are subject to
environmental regulation pursuant to a variety of Canadian, U.S. and other
federal, provincial, territorial, state and municipal laws and regulations
(collectively, "environmental legislation").

         Environmental legislation imposes, among other things, restrictions,
liabilities and obligations in connection with the generation, handling, use,
storage, transportation, treatment and disposal of hazardous substances and
waste and in connection with spills, releases and emissions of various
substances to the environment. Environmental legislation also requires that
wells, facility sites and other properties associated with our operations be
operated, maintained, abandoned and reclaimed to the satisfaction of applicable
regulatory authorities. In addition, certain types of operations, including
exploration and development projects and changes to certain existing projects,
may require the submission and approval of environmental impact assessments or
permit applications. Compliance with environmental legislation can require
significant expenditures, including expenditures for clean up costs and damages
arising out of contaminated properties and failure to comply with environmental
legislation may result in the imposition of fines and penalties. Although it is
not expected that the costs of complying with environmental legislation will
have a material adverse effect on our financial condition or results of
operations, no assurance can be made that the costs of complying with
environmental legislation in the future will not have such an effect.


                                       24


         In 1994, the United Nations' Framework Convention on Climate Change
came into force and three years later led to the Kyoto Protocol (the "Protocol")
which requires, upon ratification, nations to reduce their emissions of carbon
dioxide and other greenhouse gases. In December 2002, the Canadian federal
government ratified the Protocol. If certain conditions are met and the Protocol
enters into force internationally, Canada will be required to reduce its
greenhouse gas (GHG) emissions. Currently the upstream crude oil and natural gas
sector is in discussions with various provincial and federal levels of
government regarding the development of greenhouse gas regulations for the
industry. It is premature to predict what impact these potential regulations
could have on EnCana's sector but it is possible that EnCana would face
increases in operating costs in order to comply with a GHG emissions target.

ENCANA MAY BE ADVERSELY AFFECTED BY LEGAL PROCEEDINGS RELATED TO ITS
DISCONTINUED MERCHANT ENERGY TRADING OPERATIONS.

         An action has been filed by E. & J. Gallo Winery in the United States
District Court, Eastern District of California, against EnCana Corporation and
its wholly-owned U.S. marketing subsidiary alleging that they engaged in a
conspiracy with unnamed competitors in the natural gas and derivatives market in
California in violation of U.S. and California anti-trust and unfair competition
laws to artificially raise the price of natural gas through various means
including the illegal sharing of price information through online trading, price
indexes and wash trading. The Gallo complaint claims damages in excess of US$30
million, before potential trebling under California laws. A motion by EnCana to
dismiss the Gallo complaint on the basis that the Federal Energy Regulatory
Commission had exclusive jurisdiction regarding this matter was not granted.

         In addition, EnCana Corporation and its wholly-owned U.S. marketing
subsidiary, along with other energy companies, have been named as defendants in
several class action lawsuits in California and New York federal and state
courts. The California lawsuits relate to sales of natural gas in California
from 1999 to the present and contain essentially similar allegations as in the
Gallo complaint. The New York lawsuits claim that the defendants' alleged
manipulation of natural gas price indexes resulted in higher prices of natural
gas futures and option contracts traded on the New York Mercantile Exchange
(NYMEX) during the period from January 1, 2000 to December 31, 2002. Most of the
California lawsuits have been consolidated in Nevada District Court and all of
the New York lawsuits have been consolidated in New York District Court. As is
customary, none of the class actions specify the amount of damages claimed.
There is no assurance that there will not be other actions arising out of these
allegations on behalf of the same or different classes.

         We intend to vigorously defend against any claims of liability alleged
in these lawsuits; however, we cannot predict the outcome of these proceedings
or the commencement or outcome of any future proceedings against EnCana or
whether any such proceeding would lead to monetary damages which could have a
material adverse effect on our financial position.

OUR OPERATIONS ARE SUBJECT TO THE RISK OF BUSINESS INTERRUPTION AND CASUALTY
LOSSES.

         Our business is subject to all of the operating risks normally
associated with the exploration for and production of crude oil and natural gas
and the operation of midstream facilities. These risks include blowouts,
explosions, fire, gaseous leaks, migration of harmful substances and crude oil
spills, any of which could cause personal injury, result in damage to, or
destruction of, crude oil and natural gas wells or formations or production
facilities and other property, equipment and the environment, as well as
interrupt operations. In addition, all of our operations will be subject to all
of the risks normally incident to the transportation, processing and storing of
crude oil, natural gas and other related products, drilling of crude oil and
natural gas wells, and the operation and development of crude oil and natural
gas properties, including encountering unexpected formations or pressures,
premature declines of reservoirs, blowouts, equipment failures and other
accidents, sour gas releases,


                                       25


uncontrollable flows of crude oil, natural gas or well fluids, adverse weather
conditions, pollution and other environmental risks.

         The occurrence of a significant event against which we are not fully
insured could have a material adverse effect on our financial position.

OUR FOREIGN OPERATIONS WILL EXPOSE US TO RISKS FROM ABROAD WHICH COULD
NEGATIVELY AFFECT OUR RESULTS OF OPERATIONS.

         Some of our operations and related assets are located in countries
outside North America, some of which may be considered to be politically and
economically unstable. Exploration or development activities in such countries
may require protracted negotiations with host governments, national oil
companies and third parties and are frequently subject to economic and political
considerations, such as taxation, nationalization, expropriation, inflation,
currency fluctuations, increased regulation and approval requirements,
governmental regulation and the risk of actions by terrorist or insurgent
groups, any of which could aversely affect the economics of exploration or
development projects.

WE ARE SUBJECT TO INDEMNIFICATION OBLIGATIONS IN CONNECTION WITH PANCANADIAN'S
SPIN-OFF FROM CANADIAN PACIFIC LIMITED.

         In connection with PanCanadian's spin-off from Canadian Pacific Limited
("CPL") on October 1, 2001, PanCanadian entered into an arrangement agreement
with certain other parties to the spin-off which contains a number of
representations, warranties and covenants, including (a) an agreement by each of
the parties to indemnify and hold harmless each other party on an after-tax
basis against any loss suffered or incurred resulting from a breach of a
representation, warranty or covenant; and (b) a covenant that each party will
not take any action, omit to take any action or enter into any transaction that
could adversely impact certain tax rulings received in connection with the
spin-off, including government opinions and related opinions of counsel and the
assumptions upon which they were made.

         With respect to Canadian taxation, in addition to various transactions
that the respective parties were prohibited from undertaking prior to the
implementation of the CPL arrangement, after the implementation of the CPL
arrangement, no party generally is permitted to dispose of or exchange more than
10% of its assets or, among other things, undergo an acquisition of control
without severe adverse consequences where such disposition or acquisition of
control is for Canadian tax purposes part of a "series of transactions or
events" that includes the CPL arrangement, except in limited circumstances.

         Should we be found to have breached our representations and warranties
or should we fail to satisfy the contractual covenants, we would be obligated to
indemnify the other parties to the arrangement agreement for losses incurred in
connection with such breach or failure. In addition, we are required to
indemnify the parties to the arrangement agreement against any loss which they
may incur resulting from a claim against us, their respective businesses or
their respective assets, whether arising prior to or after the completion of the
CPL arrangement. An indemnification claim against us pursuant to the provisions
of the arrangement agreement could have a material adverse effect upon us.

                              PLAN OF DISTRIBUTION

         We may sell debt securities to or through underwriters or dealers and
also may sell debt securities directly to purchasers or through agents. These
debt securities may be sold in Canada, the United States and elsewhere where
permitted by law.

         The distribution of debt securities of any series may be effected from
time to time in one or more transactions:

         o        at a fixed price or prices, which may be changed;


                                       26


         o        at market prices prevailing at the time of sale; or

         o        at prices related to such prevailing market prices to be
                  negotiated with purchasers.

         In connection with the sale of debt securities, underwriters may
receive compensation from us or from purchasers of debt securities for whom they
may act as agents in the form of concessions or commissions. Underwriters,
dealers and agents that participate in the distribution of debt securities may
be deemed to be underwriters and any commissions received by them from us and
any profit on the resale of debt securities by them may be deemed to be
underwriting commissions under the United States Securities Act of 1933, as
amended (the "Securities Act").

         The prospectus supplement relating to each series of debt securities
will also set forth the terms of the offering of the debt securities, including
to the extent applicable, the initial offering price, our proceeds from the
offering, the underwriting concessions or commissions, and any other discounts
or concessions to be allowed or reallowed to dealers. Underwriters with respect
to each series sold to or through underwriters will be named in the prospectus
supplement relating to such series.

         Under agreements which may be entered into by us, underwriters, dealers
and agents who participate in the distribution of debt securities may be
entitled to indemnification by us against certain liabilities, including
liabilities under the Securities Act. The underwriters, dealers and agents with
whom we enter into agreements may be customers of, engage in transactions with
or perform services for us in the ordinary course of business.

         Each series of debt securities will be a new issue of securities with
no established trading market. Unless otherwise specified in a prospectus
supplement relating to a series of debt securities, the debt securities will not
be listed on any securities exchange or on any automated dealer quotation
system. Certain broker-dealers may make a market in the debt securities, but
will not be obligated to do so and may discontinue any market making at any time
without notice. We cannot assure you that any broker-dealer will make a market
in the debt securities of any series or as to the liquidity of the trading
market, if any, for the debt securities of any series.

                                INTEREST COVERAGE

         The following sets forth interest coverage ratios for EnCana calculated
for the twelve month period ended December 31, 2003 based on audited financial
information and for the twelve month period ended June 30, 2004 based on
unaudited financial information. The interest coverage ratios do not give effect
to the debt securities offered by this prospectus since the aggregate principal
amount of debt securities that will be issued hereunder and the terms of issue
are not presently known. The interest coverage ratios set out below have been
prepared and included in this prospectus in accordance with Canadian disclosure
requirements. The interest coverage ratios set out below do not purport to be
indicative of interest coverage ratios for any future periods. In calculating
the ratios, the interest expense on long-term debt has been adjusted to give
effect to the following issuances and repayments of long term debt subsequent to
December 31, 2003: the issuance of $1 billion of notes by our indirect wholly
owned subsidiary, EnCana Holdings Finance Corp., on May 13, 2004; the issuance
of $1 billion of notes by us on August 4, 2004 and the application of the net
proceeds of such issuance to repay bank and commercial paper indebtedness; the
borrowing in May 2004 of approximately $1.7 billion under a non-revolving term
loan facility to finance our acquisition of Tom Brown, Inc.; the redemption on
March 23, 2004 of our coupon reset subordinated term securities and on August 9,
2004 of our 8.50% Preferred Securities, and the borrowings incurred to fund
such redemptions; and the repayment of approximately $288 million of
indebtedness using proceeds received from recent dispositions.


                                       27


Adjustments for other normal course issuances and repayments of long-term debt
subsequent to December 31, 2003 would not materially affect the ratios and, as a
result, have not been made.

                                              December 31, 2003    June 30, 2004
                                              -----------------    -------------

Interest coverage on long-term debt:
  Net earnings................................        7.8 times        4.5 times
  Cash flow...................................       11.7 times       11.7 times

         Interest coverage on long-term debt on a net earnings basis is equal to
net earnings before interest on long-term debt and income taxes divided by
interest expense on long-term debt. Interest coverage on long-term debt on a
cash flow basis is equal to cash flow before interest expense on long-term debt
and cash income taxes divided by interest expense on long-term debt. EnCana's
net earnings before interest on long-term debt and income taxes for the 12
months ended December 31, 2003 was $3.1 billion and for the 12 months ended June
30, 2004 was $1.9 billion. For purposes of calculating the interest coverage
ratios set forth herein, long-term debt includes the current portion of
long-term debt.

                                  LEGAL MATTERS

         Unless otherwise specified in the prospectus supplement relating to a
series of debt securities, certain legal matters relating to Canadian law will
be passed upon for us by Macleod Dixon LLP, Calgary, Alberta, Canada. Certain
legal matters in connection with the offering relating to United States law will
be passed upon for us by Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York,
New York. In addition, certain legal matters relating to United States law will
be passed upon for any underwriters, dealers or agents by Shearman & Sterling
LLP, Toronto, Ontario, Canada.

         The partners and associates of Macleod Dixon LLP and Paul, Weiss,
Rifkind, Wharton & Garrison LLP as a group beneficially own, directly or
indirectly, less than 1% of any class of our securities.

INDEMNIFICATION


         Under the CANADA BUSINESS CORPORATIONS ACT (the "CBCA"), EnCana
Corporation (the "Registrant") may indemnify a present or former director or
officer of the Registrant or another individual who acts or acted at the
Registrant's request as a director or officer, or an individual acting in a
similar capacity, of another entity, against all costs, charges and expenses,
including an amount paid to settle an action or satisfy a judgment, reasonably
incurred by the individual in respect of any civil, criminal, administrative,
investigative or other proceeding in which the individual is involved because of
that association with the Registrant or other entity. The Registrant may not
indemnify an individual unless the individual acted honestly and in good faith
with a view to the best interests of the Registrant, or, as the case may be, to
the best interests of the other entity for which the individual acted as a
director or officer or in a similar capacity at the Registrant's request and in
the case of a criminal or administrative action or proceeding that is enforced
by a monetary penalty, the individual had reasonable grounds for believing that
the conduct was lawful. The indemnification may be made in connection with a
derivative action only with court approval. The aforementioned individuals are
entitled to indemnification from the Registrant as a matter of right if they
were not judged by the court or other competent authority to have committed any
fault or omitted to do anything that the individual ought to have done. The
Registrant may advance moneys to the individual for the costs, charges and
expenses of a proceeding; however, the individual shall repay the moneys if the
individual does not fulfill the conditions set out above.

         The by-laws of the Registrant provide that, subject to the limitations
contained in the CBCA, the Registrant shall indemnify a director or officer, a
former director or officer, or a person who acts or acted at the Registrant's
request as a director or officer of a body corporate of which the Registrant is
or was a shareholder or creditor, and his heirs and legal representatives
against all costs, charges and expenses, including an amount paid to settle an
action or satisfy a judgment, reasonably incurred by him in respect of any
civil, criminal or administrative action or proceeding to which he was made a
party by reason of being or having been a director or officer of the corporation
or such body corporate, if he acted honestly and in good faith with a view to
the best interests of the corporation, and in the case of a criminal or
administrative action or proceeding that is enforced by a monetary penalty, he
had reasonable grounds for believing that his conduct was lawful.

         The by-laws of the Registrant provide that the Registrant may, subject
to the limitations contained in the CBCA, purchase, maintain, or participate in
insurance for the benefit of any director, officer, or certain other persons, as
such against any liability incurred by him in his capacity as a director or
officer of the Registrant or as a director or officer of any body corporate
where he acts or acted in that capacity at the Registrant's request. The
Registrant has purchased third party director and officer liability insurance.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.
