Much of Central Canada, Manitoba and Saskatchewan were placed under special air quality statements or warnings on Monday due to smoke from wildfires, as Environment Canada advised residents to limit time outdoors and watch for smoke exposure symptoms. The weather agency said air quality was poor across swaths of Ontario and Quebec as westerly winds brought in smoke from forest fires in the Prairies and northern Ontario. The weather agency also issued air quality warnings in central Saskatchewan and a special statement for much of Manitoba, noting that air quality and visibility due to wildfire smoke can fluctuate over short distances and vary from hour to hour.
