Smoke from wildfires in the northwestern parts of the province is affecting air quality in the local region.
There is a special air quality statement in effect for Grey, Bruce, and Wellington although modelling does show some smoke over Huron and Perth. Environment Canada says high levels of air pollution due to the smoke could redevelop this afternoon in those areas.
The mixture of particles and gases in wildfire smoke contains many chemicals and experts say it can be harmful to your health.
You may experience coughing, throat irritation, headaches, or shortness of breath.
Children, seniors and people with cardiovascular or lung diseases like asthma are especially at risk.
