Canada AQHI Map — Current Air Quality Health Index
This focused map starts with current ECCC AQHI station observations enabled. Numbered station markers show the latest usable health-risk index reported for each location, while wildfire incidents, satellite hotspots, CWFIS records, and the FireWork smoke forecast start turned off.
What this map shows
Current station observations
Each numbered marker represents the newest usable AQHI observation available from an ECCC reporting location.
Health-risk categories
Marker styling separates low, moderate, high, and very-high AQHI risk ranges while preserving the reported numeric value.
An isolated air-quality view
Official fires, recent out fires, satellite hotspots, CWFIS records, and the wildfire-smoke forecast start turned off.
How to interpret it
AQHI is not smoke-only
Wildfire smoke can increase AQHI, but ozone, nitrogen dioxide, other fine-particle sources, and local atmospheric conditions also affect the index.
Stations describe their area
A station observation is not a measurement at every point around it. Conditions can vary over short distances and between reporting times.
Use official health guidance
AQHI communicates health risk. Follow official ECCC, provincial, territorial, and local health guidance for recommended actions.
Coverage and limitations
AQHI observations are station-based and can be unavailable, delayed, or geographically sparse. The nearest marker may not represent conditions at a specific address, and a low value does not prove that smoke or other pollution is absent everywhere nearby. FireRadar rejects stale or malformed upstream data rather than displaying it as a current zero-risk observation.
Common questions about this map
What does the AQHI map show?
It shows the newest usable Air Quality Health Index observation available from participating ECCC reporting locations across Canada.
Is AQHI a wildfire smoke measurement?
No. Wildfire smoke can raise AQHI, but the index reflects combined health risk from multiple air pollutants and local atmospheric conditions.
Why might there be no AQHI marker near me?
AQHI coverage depends on participating reporting locations and current usable observations. Some remote or rural areas have limited station coverage.
How current are the observations?
FireRadar requests ECCC's latest observations and rejects records older than its configured freshness window rather than presenting stale values as current.
