Special Air Quality Statement
Issued: 1:23 PM May. 13, 2025 – Environment and Climate Change Canada
Smoke is causing or expected to cause poor air quality and reduced visibility. Smoke plumes from forest fires in southeastern Manitoba and northwestern Ontario near the Manitoba border are affecting the area. The worst conditions are expected for locations near to the Ontario-Manitoba border. Smoke may continue to affect the area through Wednesday. ### 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.
