Thunder Bay Air Quality Map

How to read AQHI around Thunder Bay
Thunder Bay air quality can change as regional wildfire smoke moves around Lake Superior and interacts with local weather. AQHI observations summarize combined pollutant health risk at reporting stations and should not be extrapolated as an exact reading across remote shoreline, rural, or inland areas.
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 Thunder Bay, 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 Thunder Bay. 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.
