Air Quality Crisis: Wildfire Smoke Blankets Canada, Urgent Alerts Issued

UPDATE: Canada is currently grappling with severe air quality issues due to extensive wildfires raging across the Prairies. As of Monday morning, July 15, 2025, Toronto faced the alarming status of having the second-worst air quality in the world, prompting urgent health warnings for residents.

Thick smoke from the wildfires is expected to linger throughout Monday and into Tuesday, particularly affecting areas from Toronto to Halifax. The region is experiencing a hazardous air quality health index (AQHI) value of 7 in Windsor and Toronto, indicating significant health risks, especially for those with chronic conditions.

Authorities are advising individuals to limit outdoor exposure, particularly in southern Ontario, southern Quebec, and the Maritimes, where poor air quality can exacerbate existing health issues. This is not just a local problem; air quality ratings are anticipated to remain poor across much of Eastern Canada as the smoke continues to drift and settle.

In the west, Fort McMurray, Alberta, is facing the most severe conditions today, with a concerning AQHI forecast of 9. Slightly better conditions are reported in Prince Albert and Regina, Saskatchewan, with AQHI values of 6 and 5, respectively, while Winnipeg, Manitoba, is seeing a value of 4.

Despite these alarming conditions, officials project a gradual improvement in air quality starting from the west. Northern Ontario could see some relief today, followed by southern regions on Tuesday, but eastern provinces may not experience significant improvement until midweek.

The lingering smoke not only impacts air quality but also creates striking yet eerie sunrises and sunsets. Health experts emphasize that vulnerable populations, such as the elderly and those with respiratory issues, should take extra precautions.
