‘High risk’ air quality from wildfire smoke to linger over Ontario until Friday evening

Wildfire smoke from Western Canada has drifted into Toronto and most of Ontario, causing poor air quality and prompting health advisories. Jazan Grewal reports.

Environment Canada’s special air quality statement for Toronto, the GTA and most of Ontario remains in effect Friday due to wildfire smoke that has blanketed the region.

“High risk air quality due to wildfire smoke is expected over the area into this evening,” the statement reads. “Northerly winds this evening should improve air quality.”

As of 8 p.m. on Friday, the air quality index in Toronto is sitting at 9, which is high risk. It is forecast to fall to 4 on Saturday, which is considered a moderate risk.

The national weather agency recommends limiting your time outdoors due to poor air quality and reduced visibility.

People most impacted by air pollution, including those 65 years of age and older, pregnant women, and those with existing illnesses, should also reschedule any strenuous activities outdoors, according to the national weather service.

Mild and common symptoms of increased smoke levels include eye, nose and throat irritation, headaches or a mild cough.

Wildfires burning in Alberta, Saskatchewan, and Manitoba have forced thousands of Canadians to flee their homes and sent smoke as far as Europe.

CityNews’ meteorologist Jessie Uppal said Toronto could see conditions that could be worse than last summer, as experts are predicting a hotter-than-normal season for much of the country.

“Those hot, dry conditions spell trouble when it comes down to the wildfire threat,” said Uppal.
