Questions about FireRadar, answered
Start here for the practical differences between official wildfire incidents, national and satellite context, smoke forecasts, AQHI, retained FireRadar history, accounts, and sharing.
Understanding the wildfire map
What FireRadar shows, where it comes from, and why different wildfire datasets are kept separate.
What is FireRadar?
FireRadar is Canada's wildfire map: an independent Canada-wide interface that prioritizes direct official wildfire incidents where public jurisdiction feeds are available, uses explicitly labelled national continuity when needed, and keeps satellite, smoke, air-quality, and historical context distinct.
Is FireRadar an official emergency service?
No. FireRadar is an independent situational-awareness product and does not issue evacuation orders or emergency instructions. For urgent decisions, follow the responsible provincial, territorial, municipal, Indigenous, or emergency-management authority.
Why can FireRadar counts differ from a government map?
Sources can publish at different times, use different status definitions, or include different record types. FireRadar prioritizes direct jurisdiction incidents, can use explicitly labelled CWFIS national continuity when direct coverage is unavailable or degraded, and keeps NASA satellite hotspots separate so unlike datasets are not silently added together.
How often does wildfire data update?
FireRadar refreshes source data on its own ingestion schedule, but the meaningful freshness also depends on when the responsible source last published an update. Fire cards keep agency/source update time separate from when FireRadar retrieved the record.
What does suspected cause mean on a fire card?
When the responsible source publishes a suspected or reported cause, FireRadar shows it directly on the fire card. Cause information can change as an investigation develops, and FireRadar leaves it unavailable rather than guessing when the source does not publish one.
Are satellite hotspots confirmed wildfires?
No. NASA FIRMS hotspots are satellite thermal detections. They can support wildfire awareness, but they are not confirmed incident records or exact fire perimeters and can include repeated detections or other heat sources.
Forecasts versus observations
FireRadar deliberately distinguishes modelled wildfire smoke from observed air-quality health risk.
Is the smoke layer measured smoke?
No. The smoke layer is based on Environment and Climate Change Canada's FireWork forecast model. It is model guidance about wildfire-smoke PM2.5, not a direct measurement of what a person is breathing at a specific location.
How is AQHI different from the smoke forecast?
AQHI is an observed or forecast health-risk index based on multiple air pollutants. Wildfire smoke can affect AQHI, but AQHI is not a wildfire-smoke-only measurement. FireRadar keeps AQHI and FireWork smoke as separate layers for that reason.
What the archive actually means
FireRadar's growing observation archive is kept distinct from imported official historical datasets.
When does FireRadar observation history begin?
FireRadar's retained daily incident/perimeter observation archive begins July 20, 2026. Older official historical records can be shown or analyzed separately, but FireRadar does not relabel older agency datasets as observations FireRadar made before the service existed.
Does a missing historical day mean there were zero fires?
No. A missing or incomplete FireRadar archive day is treated as unavailable coverage, never as zero wildfire activity. FireRadar retains source-coverage and capture-health context so later analysis can distinguish a successful zero from a missing observation.
What does FireRadar retain for future historical analysis?
The history foundation retains normalized daily incident observations, append-only incident changes, immutable raw-source payload versions, source-run coverage, perimeter versions, satellite hotspot history, and separate air-quality and smoke-model history. That lets future products be derived without rewriting the original observation record.
Can FireRadar reconstruct an old day from today's map?
No. Current live wildfire state must never be written under an older observation date. Historical repairs are only supportable when retained evidence from that period can prove what was observed, and provenance must remain explicit.
Using FireRadar
The core map stays public while accounts add continuity and FireRadar Plus extends capacity.
Do I need an account to use the wildfire map?
No. The core wildfire map and public information remain available without an account. A free account adds cloud-synced Saved items, account-based history access, and limited monitoring features.
What is FireRadar Plus?
FireRadar Plus extends a free account with more Saved capacity, more monitored places, additional alert conditions, retained alert history, and other convenience features. It does not put the core public wildfire map behind a paywall.
What happens when I share an individual fire?
FireRadar creates a fire-specific map link that preserves the selected incident and location. Supported link previews use the fire name so recipients can tell which incident was shared before opening the map.
Still need help?

FireRadar keeps unlike datasets and timestamps separate because clarity about what the data actually represents matters more than making every number look perfectly aligned.
