In its latest update, issued at 6:40 am, Environment Canada said smoke from wildfires in northwestern Ontario is expected to move back into the region later today or this evening, bringing very poor air quality and reduced visibility. Poor air quality could continue into the weekend.
As smoke levels increase, Environment Canada is encouraging residents to limit time outdoors and consider reducing or rescheduling outdoor sports, activities and events.
Health officials say smoke can affect everyone, but older adults, pregnant people, infants and young children, people with existing health conditions and those who work outdoors are at greater risk. Those individuals should reduce or reschedule strenuous outdoor activities and seek medical attention if symptoms develop.
Common symptoms of smoke exposure include eye, nose and throat irritation, headaches and a mild cough. More serious symptoms, such as wheezing, chest pain or a severe cough, require immediate medical attention.
