A special air quality statement was in effect for the City of Calgary Saturday morning.
Environment Canada issued the statement just after 7 a.m., before lifting the advisory just before 11 a.m.
The government agency had said elevated pollution levels were occurring and conditions would improve later in the morning.
Pollutants can build up in areas during cold weather when there is little wind to disperse the particles.
Calgary’s temperature at the airport ranged from -1 C to -3 C Saturday morning, with calm winds.
Those calm winds, along with a temperature inversion and stagnant air caused the smog, as pollution was trapped close to the ground under a layer of warm air.
