Ontario Wildfire Map
Ontario covers an enormous area, and most wildfire activity occurs well north of the province's largest population centres. This page makes the official active-fire markers easier to scan while retaining source and freshness context.

What FireRadar has observed in Ontario
These are derived FireRadar archive statistics for direct-official Ontario incident observations only. The coverage window is shown explicitly because the FireRadar archive is not a complete 2026 wildfire-season record.
Migration baseline fires can count toward the unique-fire archive universe but are never relabelled as first observed by FireRadar. Reported-size changes reflect source-reported incident values and are not cumulative area burned or a FireRadar fire-growth estimate.
Explore wildfire regions in Ontario
Regional pages bridge the province-wide view and individual community maps with curated geographic extents, current official incidents, smoke and AQHI context, and links into local pages.
Data trust & freshness
- Source last updated
- FireRadar retrieved
- Page generated
These timestamps are intentionally separate: the responsible agency owns the source update, FireRadar records when it retrieved the data, and page generation does not replace either timestamp.
Ontario wildfire map and current Ontario fires
The Ontario wildfire map uses direct Ontario AFFES/LIO incident records for the official fire view, with source status and timestamps preserved where available. This is the canonical FireRadar page for Ontario wildfire-map searches rather than creating separate year-based map pages.
CWFIS remains a separately labelled national reference layer and is not added to Ontario official totals. Wildfire smoke is also a separate ECCC FireWork forecast layer, so a smoke plume should not be interpreted as a new Ontario wildfire incident.
The current counts are intentionally shown once in the snapshot above. This section adds interpretation rather than repeating the same totals.
Ontario source methodology
Ontario AFFES/LIO records are filtered as direct official incidents. CWFIS national records remain a separately labelled reference layer and are excluded from Ontario official totals.
Status terminology
FireRadar preserves raw source meaning and normalizes display labels only where a documented source mapping exists.
Coverage limitations
Ontario totals can differ from CWFIS because the products use different publication timing, inclusion rules, identifiers, and update workflows.

Ontario wildfire FAQ
How many active wildfires are in Ontario?
FireRadar currently counts 104 active direct-official records for Ontario. The number can differ from other maps because datasets use different update times and inclusion rules.
Why can FireRadar and the official Ontario map show different totals?
Source publication timing, status interpretation, duplicate handling, retained out-fire windows, and national fallback records can differ. FireRadar links back to the owning authority so users can verify the current official record.
Does a FireRadar marker show the exact edge of a Ontario wildfire?
Not necessarily. A marker may be a source-provided incident point or a matched reference location. Use an official perimeter when one is available and follow emergency authorities for decisions.
What this map shows
- Active official fires: direct Ontario incident records where the source supplies them.
- Recent out or extinguished fires: direct official records updated within FireRadar’s 48-hour recent-out window.
- Reported hectares: summed only for active official records that contain a usable fire size.
- Satellite hotspots: optional NASA FIRMS thermal detections, kept separate from official incidents.
Official source coverage
Integration coverage is separate from current source health. The live source summary above shows whether the direct feed is current, delayed, or unavailable right now.
Official active and new fire markers come from Ontario AFFES/LIO data. Marker data is informational and may not represent an exact perimeter.
Visit Ontario Aviation, Forest Fire and Emergency Services →How to use the Ontario wildfire map
Start with direct official active-fire markers. Select a marker to inspect its status, reported size, source dates, and cause when those fields are available.
Enable recent out fires, satellite hotspots, or the CWFIS national view separately. These layers have different meanings and should not be added together as one incident total.
Search a community or address to open a nearby-activity preview with approximate straight-line distances to official fires and satellite detections.
Important safety note
FireRadar is an informational map, not an emergency notification or evacuation service. Data can be delayed, incomplete, or revised by the source. Follow Ontario Aviation, Forest Fire and Emergency Services, local emergency services, and official evacuation instructions for decisions affecting life or property.
