Smoke from active forest fires in northwestern Ontario is affecting the air quality in parts of southern Ontario.
Environment Canada issued a special air quality statement Sunday afternoon.
The statement is currently in effect for Sauble Beach, Bruce Peninsula, Saugeen Shores, southern Bruce County, southern Grey County, Listowel, Perth County, Stratford, Wingham, Blyth, and northern Huron County.
The national weather agency said there may be high levels of air pollution throughout the day due to the combination of smoke and ground-level ozone.
Poor air quality may continue into Monday. Smoke may also cause reduced visibility in some areas.
During this time, residents may experience symptoms of coughing, throat irritation, headaches, or shortness of breath. Children, seniors, and individuals with heart or lung disease are especially at risk.
