Currently, Canada is combating over 200 active wildfires, causing smoke to drift southwards, affecting several U.S. states.
Environment and Climate Change Canada has issued air quality alerts spanning from Alberta to northern Ontario, while states like Minnesota and Michigan are experiencing “hazardous” and “very unhealthy” air quality levels.
According to alerts from Environment Canada, certain communities in Ontario may face poor air quality and diminished visibility due to lingering wildfire smoke for several days.
Warnings have been issued for northwest Alberta as well as central Saskatchewan and Manitoba. Additionally, air quality statements are active for northeast B.C., east central Alberta, Saskatchewan, and minor areas in Manitoba.
Northern U.S. states affected by smoke
Most of the impact from wildfire smoke is being felt in the upper Midwest U.S., with Minnesota warning that air quality in the east central, southeast, and northeast areas will fall into the unhealthy range, with alerts in place until Wednesday.
