What stands out about 2025
The 2025 area burned was more than six times the 2024 total.
Ontario's legislated fire season runs April 1 through October 31, while fire activity can continue outside that window.
Annual season history is distinct from the live active-fire map.

This is not a reconstructed live map of every moment in 2025, not proof of a fire’s status on a particular day, and not a substitute for agency incident archives. FireRadar’s interactive retained-history product begins with its own observation window and remains clearly separate.
