Smoke from multiple wildfires burning across Manitoba is triggering air quality warnings and special statements across much of the province.
As of Friday morning, 25 wildfires are actively burning in Manitoba, with 14 considered out of control.
The largest, fire EA061 in Nopiming Provincial Park, has grown to 124,238 hectares. A second major blaze near Flin Flon has reached 37,959 hectares.
Warnings and advisories across Manitoba
Air quality warnings from Environment Canada are in effect for northern and southeastern parts of the province, while special air quality statements have been issued for much of the rest of Manitoba. The City of Winnipeg is currently not included in either advisory.
Environment Canada warns that smoke from wildfires is causing poor air quality and reduced visibility. The situation is expected to persist, especially near the source of the fires, as warm and dry conditions continue to fuel wildfire activity this weekend.
Health risks and safety advice
During periods of heavy smoke, health risks increase for everyone, regardless of age or health status.
“Limit time outdoors. Reschedule or cancel outdoor sports, activities and events,” the warning advises.
Environment Canada says that 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—require immediate medical attention.
Those more vulnerable to outdoor air pollution, including older adults, pregnant people, infants, individuals with chronic conditions, and outdoor workers, are urged to avoid strenuous activity outdoors and monitor for symptoms.
When indoors, keep windows and doors closed as much as possible. If extreme heat is also a factor, prioritize staying cool while minimizing smoke exposure. Using a high-quality air filter in your home’s ventilation system or a certified portable air cleaner can help improve indoor air quality.
If you must be outdoors, consider wearing a properly fitted NIOSH-certified N95 respirator to reduce your exposure to fine particles. However, even with a mask, some risk remains.
Officials are also reminding residents to check in on neighbours, especially those who may be more affected by poor air quality.
