ITEM 4.01  Changes in Registrant's Certifying Accountant.

On April 8, 2005, Commercial Bankshares, Inc. (the "Company") engaged Crowe 
Chizek and Company, LLC as its independent registered certified public 
accounting firm for the year ended December 31, 2005 and the interim periods 
prior to such year-end.  The decision to retain Crowe Chizek was approved by 
the Company's Audit Committee.

During the two calendar years ended December 31, 2004 and 2003 and all 
subsequent interim periods, neither the Company nor anyone acting on behalf of 
the Company consulted with Crowe Chizek regarding either (i) the application 
of accounting principles to a specified transaction (either completed or 
proposed), (ii) the type of audit opinion that might be rendered on the 
Company's financial statements, or (iii) any matter that was either the 
subject of a disagreement or reportable event identified in paragraph 
(a)(1)(iv) or (a)(1)(v) of Item 304 of Regulation S-K.


The Company has duly caused this report to be signed on its behalf by the 
undersigned hereunto duly authorized.
