Wildfire smoke from Western Canada prompts air quality warning across Ontario. Health officials advise limited outdoor exposure overnight.
Environment Canada has issued a special air quality statement covering Toronto, the Greater Toronto Area (GTA), and much of Ontario as smoke from out-of-province wildfires is expected to affect the region overnight into Friday morning.
The agency warns that the smoke may significantly reduce visibility and degrade air quality. As levels of pollution climb, residents are urged to minimize time spent outdoors.
Vulnerable Populations Advised to Take Extra Caution
Those particularly sensitive to air pollution—including seniors, pregnant individuals, young children, and people with pre-existing conditions—are advised to avoid strenuous activities outside. Health Canada also suggests staying indoors and using air purifiers where possible.
Common symptoms of smoke exposure may include eye, throat, or nasal irritation, mild headaches, or coughing.
Smoke From Western Provinces Reaches Ontario
The degraded air quality stems from active wildfires currently burning across Alberta, Saskatchewan, and Manitoba. These fires have displaced thousands and sent smoke plumes far beyond provincial borders—even as far as Europe.
This latest development marks a continuation of Canada’s intensifying wildfire season, exacerbated by prolonged heat and dry conditions.
Meteorologists Warn of a Hotter, More Hazardous Season
CityNews meteorologist Jessie Uppal emphasized that the smoke conditions in Toronto could surpass last year’s levels. “Those hot, dry conditions spell trouble when it comes down to the wildfire threat,” Uppal said, noting that a warmer-than-average summer is forecast for much of Canada.
At the time of reporting, Toronto’s Air Quality Health Index (AQHI) stands at 4—categorized as a moderate health risk.
