Toronto Wildfire Smoke Map
Track modelled wildfire smoke around Toronto and the Greater Toronto Area with FireRadar's hourly FireWork forecast.
How to read smoke around Toronto
Toronto is far from most Canadian forest-fire zones but can still experience major smoke episodes when large fires in Ontario, Quebec, western Canada, or the United States align with regional transport. Urban heat, lake breezes, and changing winds can create large local differences between the broad forecast plume and conditions at ground level.
Forecast, not a measurement
FireWork estimates near-surface PM2.5 attributable to wildfire smoke. It can differ from actual conditions around Toronto because emissions, wind, terrain, mixing, precipitation, and model timing change. Use current AQHI observations and local health advisories when conditions matter to health.
A focused starting view, not a clipped dataset
This page starts the national FireRadar layer around Toronto. The underlying FireWork smoke field 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.
