The capital region saw plenty of wildfire smoke roll through on Sunday (July 16).
According to the Air Quality Health Index, Gibbons and Elk Island National Park got the worst of the smog in the Heartland.
Using the air quality scale, Gibbons and Elk Island reached a 7/10 (high risk), while the Fort and Bruderheim only got to a 5/10.
"We saw spikes into the high range, which for those people who have respiratory conditions it's recommended they stay indoors," said Godfrey Huybregts, communications director at Fort Air Partnership.
The moderate to high readings recorded were caused by smoke from forest fires burning in Banff National Park and in British Columbia.
