The majority of active wildfires, 91 to be exact, are in the provinces of British Columbia and Alberta.

In the United States, smoke from wildfires has reached states from Montana to Wisconsin, but it is especially intense in Minnesota on Sunday.

By mid-century, the effects of wildfire smoke could pose alarming health risks to 125 million Americans, according to the First Street Foundation.

In June 2023, smoke from Canadian wildfires covered parts of the Northeast and Midwest in a thick orange haze.

Eighteen states, from Montana to New York and as far south as Georgia, were under air quality alerts, according to AirNow at the time. New York City topped the list of the world’s worst air quality rankings by an overwhelming majority, according to IQ Air.
