In-year Fire Perimeters

Fire perimeters for this year's forest fires in Ontario.

Fire perimeters are illustrations only and may not be exact in relation to actual physical locations. The Ontario Ministry of Natural Resources does not capture perimeters for every fire. Fire perimeters are not captured in real time; each capture depends on available resources and weather conditions and may be several days old. During fire season, perimeter data is updated every 24 hours as improved information becomes available; therefore, reported fire size may fluctuate from day to day. The Ontario Ministry of Natural Resources shall not be liable in any way for the use of, or reliance upon this information.

The Forest Fire Info Map shows active fires, current fire danger and restricted fire zones in place due to high fire danger.
