For a third straight day, wildfire smoke is making it hard to breathe in parts of midwestern Ontario.
Environment Canada has a special air quality statement in effect for southern Bruce County.
Smoke from wildfires burning in northern Ontario has blown into the region which has elevated pollution levels. The national weather agency's air quality health index is expected to reach moderate to high risk levels Wednesday afternoon and evening.
"You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough," Environment Canada said. "If you think you are having a medical emergency, seek immediate medical assistance."
Those most likely to be impacted by the air pollution are seniors, small children, pregnant women, those with chronic health conditions, and outdoor workers.
People in southern Bruce County are advised to limit time outdoors and to keep windows and doors closed as much as possible.
It is hoped a cold front expected to push through the region late Thursday will also force the smoky air out.
