The Calgary Region Airshed Zone (CRAZ) encompasses an area that approximately follows the boundaries of the Calgary Health Region except for the northern border which is defined by the southern border of the Parkland Airshed Management Zone (PAMZ).

The current proposed airshed boundaries include the cities of Calgary and Airdrie; the Municipal Districts of Rocky View, Bighorn and Foothills; Willow Creek, Vulcan and Wheatland Counties; the Improvement Districts of Kananaskis and Banff; and the Town of Canmore. The Siksika, Eden Valley, Tsuu T’ina, and Stoney First Nations are also located within the CRAZ area.
