More than 830 wildfires are burning across Canada, with over 100 classified as out of control, sending thick smoke across parts of Canada and the United States. Air quality alerts remain in effect for millions of people across the Midwest and Northeast through the end of the week, with officials warning that smoke could reach unhealthy levels in several major cities.
Although Canada's 2026 wildfire season has been less severe than the record-breaking seasons of 2023 and 2025, authorities expect fire danger to increase as summer progresses.
