Worst air pollution Canadian Tire Centre - Ottawa, today and tomorrow

On 9 August 2026, overall air quality in Canadian Tire Centre is fair. AQI is the main air quality indicator at 37.4/100. Pollution peaks around 10:00 AM (O3: 37.4/100).

On 10 August 2026, air quality conditions in Canadian Tire Centre will be similar to today, with AQI forecast at fair at 34.1/100. Pollution peaks around 11:00 AM (O3: 34.1/100).

Air quality in Canadian Tire Centre shifts noticeably across the seasons, shaped by its suburban setting in Kanata, west of downtown Ottawa. The warmest months typically see the poorest air quality, with heat and heavy traffic driving up smog levels on windless days, whereas fall and winter tend to bring cleaner, more variable conditions. Its distance from the downtown core usually means slightly calmer conditions than central Ottawa.

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
