Canada wildfire observations in the available snapshot
Older cached snapshot, retrieved .
No matching usable observations for Canada were found in this retained snapshot. The selected sources are incomplete; this is not an all-clear or a count of active fires. Check the responsible fire agency for current incidents and warnings.
Three layers, three different meanings
The Canadian Wildland Fire Information System (CWFIS) map offers satellite hotspots, agency-reported active fires and fire-weather products. A hotspot is a thermal signature observed from space. An active fire is a report collected from a provincial, territorial or Parks Canada fire-management agency. A fire-weather layer describes conditions relevant to potential fire behaviour; it is not a map of fires that have already happened.
The CWFIS FAQ explains the difference between these products and their varying update schedules. Before comparing numbers, choose the same date and decide which category you mean. One large incident can generate many hotspots. A weather-index area can contain no reported fire at all. Neither marker count nor colour alone establishes the area burned.
Use the national view without losing the local authority
Canada covers multiple time zones and fire-management jurisdictions. CWFIS explicitly warns that its maps are approximations and may not show the most current situation. Its national view is useful for finding the region and product you want to investigate, but the responsible province, territory or national park publishes the local operational information. If a national product and a local report differ, inspect their update times and definitions before drawing a conclusion.
NASA FIRMS active-fire data provides another view of thermal detections, with selectable recent time windows and sensor products. Those are observations, not a second list of agency-reported incidents. Satellite revisit, obscuring cloud and resolution can leave gaps. Switching from MODIS to VIIRS can also change how many points you see without a matching change in the number of fires.
Find provincial information for BC, Alberta, Ontario and Quebec
Use the national view to choose an area, then open the responsible provincial service. These starting points help distinguish incident information from restrictions and fire danger:
- British Columbia: the BC Wildfire Service links to the current wildfire map, incident details and statistics. It provides separate resources for fire prohibitions, evacuation information and road closures. Choose the product that answers your question rather than treating an incident marker as a road or evacuation notice.
- Alberta: the provincial wildfire status guide links to active-fire locations and forest-area updates, and explains the control-status terms. An active fire need not be out of control: a fire classified as under control can still emit smoke while crews work on remaining hotspots. Read the reported status before interpreting a point as a newly spreading fire.
- Ontario: the provincial forest-fire page is the starting point for the interactive fire map, current danger and restrictions. Keep these categories separate: an active-fire location describes an incident, while a danger layer or restriction applies a different definition to an area. Retain the selected layer and update time when sharing a view.
- Quebec: SOPFEU separates active fires (feux actifs), fire danger (indice de danger d’incendie) and restrictions. Its situation view also distinguishes the intensive-protection and northern zones. Check the selected zone and product before comparing a displayed total with a national count.
For smoke over a community, follow the Canadian AQHI and smoke-forecast guide. It explains which products describe local air-quality reports and which describe a forecast plume; neither can be reconstructed from a count of fire markers.
How to investigate a Canadian map marker
Begin at the PocketWorld wildfire overview and inspect the source and observation time for the layer you selected. Follow the provider record when available. For a broader Canada-specific comparison, open CWFIS and select hotspots, active fires or fire weather deliberately. If you are looking into smoke, remember that a hotspot map does not show a smoke plume or local air quality. Do not infer exposure at a particular address from the location of a thermal point.
Write down whether you are describing a satellite observation, a jurisdictional report or a weather index. In a shared note, include the date and time zone of the observation and the date you retrieved it. This matters especially when comparing an archived screenshot with today's page or with an agency's later revised fire report.
When the map is not enough
For travel, evacuation or property decisions, use current instructions from the relevant local emergency and fire authority. PocketWorld does not issue warnings and may show delayed or retained data. An apparently clear map is not an all-clear. Our source registry explains provenance; the hotspot guide explains why satellite pixels cannot be read as precise fire boundaries.
Data sources
The regional sample uses retained NASA EONET reports and selected NASA FIRMS thermal detections, with separate observation and retrieval dates. It is not a complete incident register. Official incident, perimeter and fire-weather references are linked beside the guide's explanations.
