Smoke from wildfires in the Canadian Prairies will cause poor air quality and reduced visibilities on Saturday. Conditions will gradually improve on Sunday. People most likely to suffer health effects from air pollution, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition and people who work outdoors, should avoid strenuous activities outdoors and seek medical attention if experiencing symptoms. ### As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events. 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. If you think you are having a medical emergency, seek immediate medical assistance. People more likely to be impacted by outdoor air pollution, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms.
