Wildfires burning across the Prairies have caused widespread poor air quality and reduced visibility across a large part of Canada, affecting British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, and Newfoundland and Labrador. Environment Canada expects the situation to improve over the weekend due to a low-pressure system bringing precipitation to some affected areas, though northern Alberta may see little relief.

Trending- 1 Thursday and Friday: Southern Ontario was under an air quality statement.
- 2 Saturday: A large swath of Canada experienced poor air quality and reduced visibility due to Prairie wildfires.
- 3 Saturday: Environment Canada meteorologist Jean-Philippe Bégin provided an update on the situation.
- 4 Over the weekend: The air quality situation is expected to improve in most affected areas.
- 5 By Monday: A low-pressure system is expected to move into Manitoba and northwestern Ontario, bringing precipitation.
- Poor air quality and reduced visibility across multiple provinces
- Health risks, especially for vulnerable populations (children, pregnant women, elderly, those with heart/respiratory issues)
- Public health advisories (e.g., keep windows closed, reduce outdoor activities, limit non-essential travel)
- Significant impact on daily life and outdoor activities
What: Wildfires burning in the Prairies are causing widespread poor air quality and reduced visibility across a large portion of Canada.
When: Saturday (current situation), Thursday and Friday (Southern Ontario under air quality statement), over the weekend (expected improvement), by Monday (low-pressure system movement).
Where: Prairies (source of fires), British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, Newfoundland and Labrador (affected areas). Specifically mentioned: Toronto, Montreal, northern Saskatchewan, northwestern Ontario, northern Manitoba, northern Alberta, eastern Quebec, Quebec's North Shore, southern Quebec.
Why: Forest fires are releasing high concentrations of fine particulate matter into the atmosphere, which is then carried by weather systems across the country.
How: Smoke plumes from active wildfires are impacting air quality far from the fire sources. A low-pressure system is expected to bring precipitation, which should help clear the air in some regions.
