With the Government of Alberta's establishment of the Calgary Metropolitan Region Board (CMRB) in 2017, the CMR's boundaries were legislated to include the City of Calgary, Foothills County to the south, Rocky View County to the west, north, and east, and a western portion of Wheatland County further to the east. Also within these boundaries are the cities of Airdrie and Chestermere, eight towns (Black Diamond, Cochrane, Crossfield, High River, Irricana, Okotoks, Strathmore, and Turner Valley), two villages (Beiseker and Longview), and two First Nations communities (Tsuu T'ina 145 and Eden Valley 216), though not all are participating members of the CMRB.
