Officials warns of poor air as Alberta fire smoke spreads to Saskatchewan

REGINA — Health officials in Saskatchewan are telling people to take precautions as smoke from forest fires in Alberta spreads across Saskatchewan.

Chief medical health officer Dr. Saqib Shahab says smoke can cause increased coughing, throat irritation, headaches and shortness of breath.

People with lung and heart conditions, older adults and seniors are particularly at risk.

Shahab says healthy people typically don't experience symptoms, but should also reduce or reschedule strenuous outdoor activities if smoke levels are high.

Environment Canada has issued a special air quality statement as winds spread smoke from the wildfires in northeastern Alberta into portions of western Saskatchewan.

It says high levels of particulate may persist until the fire is put out or controlled.
