Ontario Wildfire Risk Map
Ontario's fire region spans the vast boreal northwest — Kenora, Red Lake, Sioux Lookout — where lightning drives most large fires. In big seasons like 2021, Ontario's largest area burned on record, northern fires send smoke across the province and beyond.

How the 0–100 Ontario risk score works
Model ca-v1.0 (2026-08)A transparent weighted blend of four openly-licensed federal datasets, pulled live for your exact coordinates — the same 0–100 scale and tier bands as our U.S. reports, so a High here means the same thing everywhere. Government danger maps are labeled inputs, never re-badged as our score.
NFDB large-fire records + NBAC mapped burns (NRCan) — distance-decayed, since 2000
CWFIS official danger class at the point (SCRIBE forecast, updated daily)
CWFIF national active fires within 40 km — distance, stage of control, size
Copernicus DEM elevation — fire spreads up to 8× faster uphill
Ontario wildfire risk FAQ
How risky is Ontario for wildfire?
Ontario's fire region spans the vast boreal northwest — Kenora, Red Lake, Sioux Lookout — where lightning drives most large fires. In big seasons like 2021, Ontario's largest area burned on record, northern fires send smoke across the province and beyond. Risk varies enormously street to street — the free report scores your exact address on a 0–100 scale from federal Canadian data.
How is the 0–100 Canadian score calculated?
It blends four openly-licensed federal datasets, pulled live for your coordinates: burn history near the address (NFDB + NBAC, 35%), today's official fire-danger class (CWFIS, 30%), live fire activity within 40 km (CWFIF, 20%), and slope (15%). A source with no data for your point is dropped and the weights renormalize — never guessed. The full formula is published on the methodology page.
Is this the same as the government fire danger rating?
No — government danger maps are labeled inputs, never re-badged as our score. The official CWFIS danger class near your address appears inside the report as its own factor, shown with its official class name.
How do I check a Ontario address?
Use the score checker above — type any street address, and the free report returns the 0–100 score, the factor breakdown, fire history within 40 km, live fires, and a satellite view of the property. No signup required.
