Canada’s fire season erupts, sending harmful smoke into United States

Wildfires in Canada have roared back to life, sending harmful smoke into the northern United States — an unwelcome reminder of last summer’s historic fire season that also repeatedly sent plumes of noxious haze southward.

Almost a year to the date from the explosive start to the 2023 fire season, hundreds of fires have erupted in Canada, including a dozen major and out-of-control blazes. At least 500,000 acres (200,000 hectares) of land have burned so far, much of it in recent days.

Smoke from the blazes has led to air quality alerts for much of Alberta and its surrounding provinces, as well as Minnesota and Wisconsin. Edmonton was subjected to red-tinged skies and hazardous air quality over the weekend because of wildfires to its north.
