Canada Satellite Wildfire Hotspot Map
This page isolates recent NASA FIRMS VIIRS thermal detections over Canada. Hotspots can reveal areas of strong heat activity, but they are not the same thing as confirmed wildfire incidents, fire perimeters, official emergency areas, or official fire counts.
What this map shows
Recent thermal detections
Each visible hotspot represents a satellite-detected heat signal included in FireRadar's current Canada feed.
Relative hotspot intensity
Map styling uses available confidence, fire radiative power, and brightness values to provide visual weight where supplied.
No incident mixing
The FireRadar Wildfires and recent out-fire layers start turned off so thermal detections can be interpreted independently.
How to interpret it
A hotspot is not a confirmed wildfire
Industrial heat, repeated satellite passes, cloud conditions, and other factors can create false positives, duplicates, or missing detections.
Clusters need context
Several detections close together may relate to one fire, multiple fires, or repeated observations of the same heat source.
Use Wildfires for incident status
Enable the Wildfires layer or consult the responsible authority when you need a named incident, status, size, cause, or emergency information.
Coverage and limitations
Satellite hotspots are detection points rather than mapped fire boundaries. A location without a visible hotspot is not proof that no wildfire or smoke threat exists, and a visible hotspot is not proof of an uncontrolled wildfire. Satellite timing, orbit coverage, cloud, smoke, and source filtering all affect what appears.
Data source
FireRadar presents this view using NASA FIRMS VIIRS. The interactive map is informational and may not reflect source changes immediately.
