FireRadar for Media & Researchers
Use FireRadar to find and compare current Canadian wildfire information. Keep provincial and territorial source context with every count, and use the responsible authority for safety reporting.
Counts exclude NASA hotspots and CWFIS national fallback records. A direct source that is unavailable or cannot be confirmed is excluded rather than treated as zero. A source using the latest confirmed data is labelled that way below.
Successful source checks below belong to the displayed snapshot. Snapshot generation and publication are separate from source acquisition. Incident updates, perimeter mapping dates and first reports describe individual records, not feed freshness. Latest included source-reported incident update: .
Why the denominator is 11: Eleven provinces and territories currently publish dependable, machine-readable active-wildfire feeds that FireRadar can use directly. Prince Edward Island and Nunavut do not currently publish dependable, up-to-date provincial or territorial active-wildfire feeds. They are outside the direct-source denominator rather than being counted as failed or zero-fire sources. Their FireRadar map pages may show separately labelled national CWFIS context if available. If either jurisdiction begins publishing a dependable direct incident feed, FireRadar will include it.
Citation-ready comparisons and recorded observations
These resources use official provincial and territorial wildfire observations saved by FireRadar. For reporting or research, cite the original source and keep the stated dates and coverage limits with the numbers.
Day-over-day new active fires, status changes, recent-out transitions, and reported-hectare movement.
Daily FireRadar activity observations with jurisdiction timelines and rankings.
Machine-readable comparison with dates, metric definitions, provenance, limitations, and jurisdiction rows.
Using FireRadar smoke maps in media
FireRadar smoke maps may be used in news and broadcast coverage. The underlying smoke forecast is Environment and Climate Change Canada's FireWork model; identify it as a forecast rather than an observation. FireRadar.ca credit is appreciated, and a link to the exact shared forecast view helps audiences inspect the source time and forecast-valid time for themselves.
Direct-source counts with source state
Largest active fires in available direct sources
This ranking uses the latest usable source-reported size attached to active records from direct sources whose current or latest-confirmed state can be shown. Missing sizes are omitted, and the result is not a ranking of cumulative national annual area burned.
Attribution
For a FireRadar-derived count or comparison, a useful attribution is: “According to FireRadar.ca, using direct provincial and territorial wildfire sources…” Then link the relevant FireRadar page and, for safety-critical reporting, the responsible official authority.
When reporting on FireRadar data-update reliability itself, use the source-check history rather than inferring uptime from a single update time.
Press, data corrections and research contact
Questions about methodology, source discrepancies, data reuse, or media citation can be sent to hello@fireradar.ca. Include the fire identifier, province or territory, source URL, and timestamp when reporting a data discrepancy.
What FireRadar should not be cited for
FireRadar does not issue official emergency notices, road closures, or predictive spread guidance. It also does not treat satellite hotspots as confirmed fires. Use responsible emergency authorities for decisions affecting life, property, travel, or personal safety.
