Environment Canada issued a special air quality statement for Calgary on Saturday morning as smoke from U.S. wildfires drifts north.
Conditions are expected to worsen through the day, causing poor air quality and reduced visibility.
“Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk,” reads a statement released by Environment Canada.
People are advised to take precautions to reduce exposure to the smoke.
Despite the Environment Canada alert, Alberta Health Services has not issued an air quality advisory.
As of 12:30 p.m. Saturday, Calgary’s air quality health index was at Level 5, indicating moderate risk. According to AHS, those at risk should consider rescheduling strenuous outdoor activities if they are experiencing symptoms, but members of the general population do not need to modify their activities.
