Toronto Air Quality Map
Check current AQHI observations around Toronto and the GTA while keeping observed health risk separate from the wildfire-smoke model.
How to read AQHI around Toronto
Toronto AQHI can reflect wildfire smoke alongside traffic, ozone, industrial emissions, and other urban pollution. During smoke events fine particles may dominate, but AQHI itself remains a multi-pollutant health-risk index and individual stations do not represent every neighbourhood identically.
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 Toronto, 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 Toronto. 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.

Smoke and air quality can change even when no confirmed wildfire is close to Toronto. Use the local wildfire page for current official incidents, the fire-danger page for broad fire-weather context, and the province view when you need a wider regional picture.
