How FireRadar handles Canadian wildfire data

Current wildfire tracking across Canada

FireRadar shows the latest available Canadian wildfire information on one map. Official incidents, CWFIS national data, satellite detections and smoke forecasts stay clearly separated so visitors can tell what each layer means.

Canada-wide sources on one map

FireRadar combines provincial, territorial, national, satellite, and smoke information on one map so you do not have to search through separate government viewers.

Local authorities first

Where available, wildfire status, size, cause and update details come from the province or territory responsible for the incident.

Clear update information

FireRadar checks connected wildfire sources regularly and shows when the source last reported an update. New information still depends on when the responsible agency publishes it.

How sources are chosen

Local wildfire authorities come first

Canadian wildfire information is published by many agencies. FireRadar gives priority to the authority responsible for each province or territory. Broader national data can fill a gap, but it is labelled and does not silently replace newer local information.

Main wildfire map

Provincial and territorial sources

The main map prioritizes current records from provincial and territorial wildfire authorities. These records support FireRadar's active-fire counts and provincial summaries where they are available.

Canada-wide information

CWFIS national data

Natural Resources Canada's CWFIS data can fill gaps when local information is unavailable. It is clearly labelled because it may be older or differ from a provincial or territorial source.

Satellite observation

NASA FIRMS hotspots

Satellite hotspots show recent thermal detections. They can help reveal possible fire activity, but they are not confirmed wildfire incidents and are never added to official fire totals.

Smoke forecast

ECCC FireWork

The smoke layer displays Environment and Climate Change Canada's FireWork forecast for the selected hour. It is model guidance, not a live air-quality reading or a wildfire incident layer.

Update times stay distinct

The time an agency updated a fire is different from the time FireRadar checked it. FireRadar shows those times separately so a recent check is not mistaken for a new agency update.

A source problem is not zero fires

If an update fails or appears incomplete, FireRadar does not clear the map or report zero fires. It may keep showing the last confirmed information with a clear notice, or mark the information unavailable.

No invented values

Missing size, cause, date, or status fields remain unavailable. FireRadar does not turn missing data into zero, guess an incident status, or combine nearby markers simply because they may represent the same event.

Current does not mean instantaneous

FireRadar cannot show a change before the responsible agency publishes it. Check the source time on the map, and always confirm urgent local information with the responsible authority.

What FireRadar cannot tell you

Source information can be delayed, incomplete, corrected later or temporarily unavailable. FireRadar is not an emergency authority and does not issue evacuation instructions or predict where a fire will spread. For safety decisions, follow the responsible provincial, territorial, Indigenous, municipal or emergency authority.

We built FireRadar to make official Canadian wildfire information easier to understand without hiding where the data came from or what it cannot prove.
