Environment Canada suggests the city’s air quality will stay at “moderate risk” levels until at least Saturday.

Canadian wildfires burning across northern Manitoba and Saskatchewan are sending smoke through central Canada, the Great Lakes region and the northeastern United States, reducing air quality and visibility in major cities. Forecasters said they were “optimistic” that the lingering wildfire smoke would ease later in the day on Tuesday.

On Monday morning, Environment Canada issued a special air quality statement for the vast majority of southern Ontario, predicting "poor air quality" as a result of forest fires.
