The dashed outline is FireRadar's curated regional counting extent. Incident points, smoke forecasts, and AQHI observations are separate datasets and should not be interpreted as evacuation boundaries or fire-spread predictions. FireRadar regional extents may overlap near transition areas. Regional totals are useful local summaries and must not be added together to produce a province total.

Stations can be far from rural or remote parts of a region. The nearest observation may not represent conditions everywhere inside the regional boundary.

Regional context

Wildfire context across Northwestern Ontario

Northwestern Ontario covers an immense boreal landscape with remote and road-access communities, lakes, forests, resource activity, aviation-dependent areas, and long highway links. Fires can be far from major population centres while still producing significant smoke or affecting travel and regional operations, so a regional view helps connect official incidents with local community pages without implying identical conditions across the entire northwest.

Northwestern Ontario smoke forecast

Use FireRadar's ECCC FireWork smoke forecast to see modelled smoke movement across and beyond Northwestern Ontario. Forecast smoke is not proof that a nearby wildfire is the source of local smoke.

Measured conditions

Air quality and AQHI

AQHI and observed PM2.5 provide measured air-quality context and remain distinct from FireWork forecast smoke. Station coverage varies across a region, especially in rural and remote areas.
