Southern Ontario is expected to see poor air quality and reduced visibility tonight due to smoke drifting in from wildfires burning across the Prairies.
A special air quality statement is in effect for Chatham-Kent.
According to Environment Canada, air quality and visibility caused by wildfire smoke can fluctuate quickly, varying considerably over short distances and time periods. Conditions are expected to improve gradually from north to south on Thursday.
As smoke levels rise, so do health risks. Residents are encouraged to limit time outdoors and consider rescheduling outdoor sports, activities and events.
Common symptoms of smoke exposure include eye, nose and throat irritation, headaches and mild coughing. More serious symptoms, such as wheezing, chest pain or a severe cough, are less common. Anyone experiencing a medical emergency should seek help immediately.
Those more vulnerable to air pollution — including older adults, pregnant people, infants, young children, those with chronic health conditions, and outdoor workers — should take extra precautions and reduce strenuous outdoor activities.
When indoors, residents should keep windows and doors closed. During periods of both heat and poor air quality, prioritize staying cool. Using a high-quality air filter or a certified portable air cleaner can help protect indoor air from wildfire smoke.
If going outdoors is unavoidable, a well-fitting respirator-type mask such as a NIOSH-certified N95 can help reduce exposure to fine particles, though health risks may still remain.
Officials also recommend checking in on those more susceptible to air pollution, such as neighbours, family or others in your care.
