Parts of southern Alberta were placed under an air quality statement on Monday as wildfire smoke from B.C. and the western U.S. settled over the province.
Environment Canada issued special air quality statements for Banff National Park, Kananaskis, Canmore, Crowsnest Pass, Pincher Creek, Waterton Lakes National Park, Cardston, Fort Macleod and Magrath just after 4:30 a.m.
In the advisory, the national weather agency warned smoke was resulting in poor air quality and reduced visibility.
“Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath,” the alert stated.
“Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.”
On Tuesday, Environment Canada warned a cold front moving through southern Alberta that afternoon could briefly worsen conditions “as smoke from aloft will be pushed down to the surface.
