LONDON, Ontario - April 10, 2026 - Platinum Air Care, a family-owned indoor air and water quality company serving over 30,000 homeowners across Southwestern Ontario since 1999, today published its 2026 Ontario Indoor Air Quality Report.
The report compiles data from Health Canada, Environment and Climate Change Canada, Statistics Canada, Public Health Ontario, and peer-reviewed studies published in Nature and the Canadian Medical Association Journal. It is the only publicly available Ontario-specific reference document that brings this data together in one place.
Five headline findings from the report:
- Canadians spend approximately 90% of their time indoors, yet fewer than half of Ontario homeowners have taken steps to assess their indoor air quality.
- Environment and Climate Change Canada issued approximately 5,000 air quality alerts in 2023 — nearly four times the annual average — driven almost entirely by wildfire smoke.
- During the June 2023 wildfire smoke episodes, daily average PM2.5 across Ontario surged from 7.4 μg/m³ to as high as 65.3 μg/m³. Asthma-related emergency department visits rose measurably during these episodes.
- Approximately 1 in 5 Canadian homes (17.8%) have radon levels at or above Health Canada's guideline of 200 Bq/m³. In Ontario, 13 of 36 health regions had more than 10% of homes above the guideline. Radon accounts for an estimated 850 lung cancer deaths in Ontario annually.
- As of January 1, 2025, Ontario's updated Building Code mandates HRV or ERV mechanical ventilation in every new home — yet the vast majority of Ontario's 5.6 million existing homes have no such system.
The report also identifies five areas where no Ontario-specific data currently exists in the public record, including aggregated radon results by Southwestern Ontario municipality, indoor PM2.5 readings during wildfire events, and duct contamination levels pre- and post-cleaning.
