A special air quality statement was issued tonight (Sunday, September 17) by Environment and Climate Change Canada (ECCC) due to wildfire smoke.

Airdrie, Cochrane, Olds and Sundre are all under the air quality statement.

"Wildfire smoke concentrations can fluctuate over short distances and vary considerably from hour to hour. Wildfire smoke can be harmful to everyone’s health even at low concentrations. Continue to take action to protect your health and reduce exposure to smoke," ECCC stated.

People with lung disease (such as asthma) or heart disease, older adults, children, pregnant people, and people who work outdoors are at higher risk of experiencing health effects caused by wildfire smoke.

"You should stay inside if you are feeling unwell and experiencing symptoms."
