Canadian Air Quality Standards
CAAQS - Canadian Ambient Air Quality Standards
Environment and Climate Change Canada sets national standards for PM2.5, ozone, NO2, and SO2. These standards are designed to protect both human health and the environment, with provinces implementing their own monitoring and enforcement programs.
Provincial Programs
Each province monitors air quality through their environmental agencies. British Columbia, Alberta, and Ontario have extensive monitoring networks, especially important during wildfire season when smoke can blanket entire regions.
Wildfire Smoke Preparedness
Canadian wildfires increasingly affect air quality across the country, particularly in BC, Alberta, and Ontario. In 2023, Canadian wildfire smoke reached as far as New York City. Having a HEPA air purifier ready can protect your family during smoke events.
2023: Record wildfire season
18.5M hectares burned across Canada
Indoor air 2-5x worse without filtration
Smoke particles infiltrate even sealed homes
HEPA removes 99.97% of particles
Effective against PM2.5 smoke particles

| Focus | Combined health risk | Individual pollutant levels |
| Pollutants | Ozone, PM2.5, NO2 combined | 6 criteria pollutants (reported separately) |
| Good range | 1-3 | 0-50 |
