Air quality warnings are in effect across central and northern Manitoba, with Environment Canada warning that wildfire smoke will spread into Winnipeg and much of the south by Saturday.
The alert for much of northern and central Manitoba cautions residents about deteriorating air quality and visibility caused by smoke, conditions expected to persist into the weekend.
"Smoke is causing or expected to cause very poor air quality and reduced visibility in some areas through the weekend," said Environment Canada in a joint statement with Manitoba Health.
The warning currently affects areas including Grand Rapids, Swan River, Poplar River, Berens River, The Pas, Norway House, Lynn Lake, Thompson, Flin Flon and Island Lake.
The public is advised to limit time outdoors, especially vulnerable populations such as older adults, young children, pregnant people, and those with pre-existing health conditions or respiratory illnesses. People who work outside are also considered at higher risk.
"During heavy smoke conditions, everyone’s health is at risk regardless of their age or health status," the statement noted.
Common symptoms from smoke exposure include throat irritation, headaches, and mild coughing. More serious symptoms like wheezing and chest pain may occur. Anyone experiencing severe symptoms should seek immediate medical attention.
Environment Canada recommends keeping windows and doors closed, using air purifiers where possible, and wearing N95 masks if time outdoors is unavoidable.
The agency also urges residents to check on neighbours or those in their care who may be more vulnerable to air pollution.
