How to read AQHI around Ottawa
Ottawa air quality can be influenced by wildfire smoke, traffic, ozone, regional transport, and local weather, while conditions can also differ across the river in Gatineau. AQHI reports combined pollutant health risk at participating stations and does not, by itself, identify the source of pollution or provide a parcel-level reading.
Observation, not a city-wide constant
AQHI values come from participating reporting locations and communicate combined health risk from multiple air pollutants. The nearest observation may not match every neighbourhood around Ottawa, and a missing marker is not evidence of clean air. Wildfire smoke is one possible contributor rather than the definition of AQHI.
A focused starting view, not a clipped dataset
This page starts the national FireRadar layer around Ottawa. The underlying AQHI station layer is not clipped to municipal boundaries, so nearby conditions remain visible as you pan or zoom. FireRadar does not infer a uniform value inside a city boundary.
Health and safety limitation
FireRadar is an informational environmental map. Follow Environment and Climate Change Canada, provincial health agencies, local public-health guidance, and emergency authorities for health or safety decisions. This page does not diagnose exposure, determine whether outdoor activity is safe, or predict individual health effects.
