CANADIAN MUNICIPALITY FORECAST
This live 48-hour ECCC RAQDPS surface-PM2.5 forecast with wildfire contributions is sampled at the Statistics Canada representative point for Laval. The field can also include anthropogenic and biogenic PM2.5, and conditions can differ across the municipality.

Open the live 48-hour forecastSeventeen ECCC RAQDPS surface-PM2.5 point samples with wildfire contributions spanning forecast hours 0–48. This official field can also include anthropogenic and biogenic PM2.5. The result remains provisional until every three-hour sample is verified.
The nearest recent ECCC AQHI observation, shown on the official 1–10+ scale and kept separate from the modeled RAQDPS field.
Current NRCan CWFIS agency-reported active-fire points. Proximity does not prove smoke origin, and Canadian v1 does not imply incident perimeters.
Smoke Window calls this modeled PM2.5 field below 4 µg/m³ “low.” Its planning window requires two consecutive three-hour samples below that site-created threshold. This is not AQHI, health guidance, or a guarantee of clean air.
NEARBY INDEXED PLACES
Smoke Window uses the ECCC RAQDPS deterministic surface-PM2.5 field with wildfire contributions for Canada. The field can also include anthropogenic and biogenic PM2.5. Model output is not a measurement, AQHI, official health recommendation, or street-level prediction. Emissions, plume rise, wind, terrain, mixing, precipitation, and forecast lead time introduce uncertainty.
