One of Canada's prairie provinces. It became a province on 1905-09-01. Alberta is located in western Canada, bounded by the provinces of British Columbia to the west and Saskatchewan to the east, Northwest Territories to the north, and by the State of Montana to the south. Statistics Canada divides the province of Alberta into nineteen census divisions, each with one or more municipal governments overseeing county municipalities, improvement districts, special areas, specialized municipalities, municipal districts, regional municipalities, cities, towns, villages, summer villages, Indian settlements, and Indian reserves. Census divisions are not a unit of local government in Alberta.
