Special air quality statement in effect for:
  • Barrie - Collingwood - Hillsdale

Smoke is causing poor air quality and reducing visibility. Smoke is expected or occurring.

High levels of air pollution due to the combination of smoke and ground level ozone are possible this afternoon.

Smoke plumes from active forest fires in northwestern Ontario might affect portions of southern Ontario this afternoon. Particulate matter combining with ground level ozone may deteriorate the air quality.

Conditions may persist into Monday.

If you or those in your care are exposed to wildfire smoke, consider taking extra precautions to reduce your exposure. Wildfire smoke is a constantly-changing mixture of particles and gases which includes many chemicals that can be harmful to your health.
