Right now the modelled US Air Quality Index for Villeray–Saint-Michel–Parc-Extension, Quebec, Canada is 61, which falls in the "Moderate" band (up to 100). Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors.

The index is driven mainly by PM2.5, whose own sub-index is 61. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.

Also this hour: UV index 1.4, carbon monoxide 233 µg/m³.

NASA FIRMS shows 10 fire hotspots within 300 km in the last day (nearest about 64 km), but particle levels are not elevated enough to point to smoke right now.
