Canada Reports More Active Wildfires Than in Past Two Years

Canada currently has more active wildfires than it did at the same stage in either of the past two years, while the area burned so far this year exceeds the 10-year average. Smoke from fires in northwestern Ontario reached Toronto on July 15, 2026, combining with a heat wave and prompting health warnings for residents to limit outdoor activity.

Calls have been made for a federal response to address the fires and smoke impacts across parts of North America.
