The smoke generated by the fires raging in the forests of western Canada worsened air quality on Friday in the Prairies, Ontario and Quebec, where warnings of smog and poor air quality were issued by Environment Canada.

Early this morning, Toronto and Montreal were among the most heavily polluted cities in the world, according to the website of the Swiss company IQAIR, which operates a global air quality monitoring network.

According to the measurements posted on the company’s website, at around 8.30 am, Montreal and Toronto were respectively the second and third most polluted cities in the world, behind Tashkent in Uzbekistan.

In Canada, the worst air quality was measured in Winnipeg and Ottawa on Friday morning.

Air quality warnings have been issued for a large swath of Manitoba, though rain could bring some much-needed relief.

Environment and Climate Change Canada (ECCC) upgraded a number of air quality statements to warnings Monday morning in a large portion of southern Manitoba, including Winnipeg, Steinbach, and Lac du Bonnet.

These areas join much of northern Manitoba, which have been under air quality warnings for days due to wildfires burning in the region and in northern Saskatchewan.

However, the weather agency notes smoke will improve with rain forecast through southern Manitoba on Monday, while northern communities under wildfire threat will likely have to wait until the weekend for precipitation.

Wildfires in western Canada will likely bring smoke into Ottawa and eastern Ontario starting on Monday and into Tuesday morning.

CTV’s Your Morning chief meteorologist Kelsey McEwen says smoke could travel as far as Quebec City by Tuesday morning with air quality advisories being issued in five provinces.

“You can see the Jetstream pulling that smoke down south of the border through the Dakotas and back up through the Great Lakes,” McEwen said.

“By tomorrow, this begins to slide toward the Ottawa-Gatineau area, tomorrow morning and out toward Quebec City.”
