Environment Canada has issued a Special Air Quality Statement for the Parry Sound region.
Officials say smoke is causing poor air quality and reducing visibility with high levels of air pollution due to smoke from ongoing forest fires.
Smoke from active forest fires in northwestern Ontario has moved over southern Ontario and elevated particulate matter levels and hazy conditions have been reported at several stations. Reduced visibility and deteriorating air quality are possible if the smoke descends to ground level.
Conditions are expected to improve Tuesday with the passage of a cold front.
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 may include many chemicals that can be harmful to your health.
Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.
