Environment Canada is prompted to issue a special air quality alert as the wildfires in British Columbia have caused a thick layer of smoke to descend on the city of Calgary and other parts of Alberta.
The environment agency says smoke from the fires is causing poor air quality as it pushes across Alberta.
Environment Canada warns that certain people may notice increased coughing, throat irritation, headaches or shortness of breath during the smokiest hours.
The agency advises that the best approach during poor air quality days is to limit outdoor activity and stay inside if you have breathing difficulties.
