has issued special air quality statements for much of Ontario and parts of western Quebec due to wildfire smoke drifting from western Canada fires. The smoke is causing or is expected to cause poor air quality and reduced visibility, especially overnight into Friday morning, June 6. In Ontario, affected regions include Toronto, the Greater Toronto Area, the Kawarthas, and midwestern counties like Huron, Bruce, and Grey.
Because the smoke is visible or affecting the air in Ottawa, other areas such as Ontario and parts of western Quebec around it are also being warned to be cautious about the air quality, as the smoke is spreading.
The hazy conditions are a result of wildfires in Canada, particularly in Alberta, Saskatchewan, and Manitoba. Due to shifting winds, massive plumes have moved eastward, affecting central and eastern regions. Residents have reported hazy skies and a distinct burning smell in several cities, including Toronto and Ottawa.Health officials warn residents to reduce outdoor activity, especially for vulnerable groups such as seniors, young children, pregnant individuals, and those with existing health issues. Exposure to wildfire smoke may irritate the eyes, nose, and throat, as well as cause headaches and coughing.
The Air Quality Health Index (AQHI) has reached moderate to high-risk levels in multiple regions. Authorities urge the public to monitor air quality, Canada wildfires updates regularly, and use smoke maps to track conditions in their area.
Due to the wildfires and poor air quality in western parts of the country, residents of Manibota's Flin Flon fled the area. The fire originated in Saskatchewan and has merged with the Sherridon fire in Manitoba. The blaze now spans over 307,000 hectares on the Manitoba side alone. Thousands of Canadians have been forced to evacuate their homes.

Though improvement is expected gradually, ground-level wildfire smoke Toronto and in surrounding areas may persist through Friday.
