Ottawa Wildfire Smoke Map
Follow forecast wildfire smoke around Ottawa, Gatineau, and the Ottawa Valley with FireRadar's hourly FireWork model guidance.
How to read smoke around Ottawa
Ottawa can receive smoke from northern and eastern Ontario, western Quebec, or long-range Canadian and U.S. fires. The Ottawa Valley and changing synoptic winds can channel or disperse smoke differently from the broad regional plume, and conditions can vary across the National Capital Region. FireWork is therefore forecast guidance rather than a direct ground-level measurement.
Forecast, not a measurement
FireWork estimates near-surface PM2.5 attributable to wildfire smoke. It can differ from actual conditions around Ottawa 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 Ottawa. 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.

Smoke and air quality can change even when no confirmed wildfire is close to Ottawa. 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.
