Environment Canada has issued a Special Air Quality Statement for much of southern Ontario as wildfire smoke from northwestern Ontario moves into the region.
Forecasters say smoke is expected to cause poor air quality and reduced visibility beginning tonight, with conditions potentially lasting through Wednesday.
Residents are being advised to limit time outdoors and consider postponing or reducing outdoor sports, activities and events as smoke concentrations increase.
Common symptoms of smoke exposure include eye, nose and throat irritation, headaches and coughing, while more serious symptoms can include wheezing, chest pain and severe coughing.
Older adults, pregnant people, young children, those with chronic health conditions and people who work outdoors are considered most at risk and should avoid strenuous outdoor activity.
Officials also recommend keeping windows and doors closed when possible, using air filtration systems indoors, and wearing a properly fitted N95 respirator if time outdoors is unavoidable. During periods of extreme heat, residents are reminded to prioritize staying cool while reducing exposure to smoke.
