The Parliament of Canada passed the Rocky Mountains Park Act, creating Banff National Park (pictured) in Alberta as the country's first national park.

The Parliament of Canada is the federal legislature of Canada. The Crown, along with two chambers: the Senate and the House of Commons, form the bicameral legislature.

The Rocky Mountains Park Act was enacted on June 23, 1887, by the Parliament of Canada, establishing Banff National Park which was then known as "Rocky Mountains Park". The act was modelled on the Yellowstone Park Act passed by the United States Congress in 1881. The Rocky Mountains Park Act outlined the national park concept, balancing conservation and development interests.

Banff National Park is Canada's first national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley.

Alberta is a province in Canada. It is a part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to its west, Saskatchewan to its east, the Northwest Territories to its north, and the U.S. state of Montana to its south. Alberta and Saskatchewan are the only two landlocked Canadian provinces. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate, but seasonal temperatures tend to swing rapidly because it is so arid. Those swings are less pronounced in western Alberta because of its occasional Chinook winds. Alberta is the fourth largest province by area, at 661,848 square kilometres, and the fourth most populous, with 4,262,635 residents. Alberta's capital is Edmonton; its largest city is Calgary. The two cities are Alberta's largest census metropolitan areas. More than half of Albertans live in Edmonton or Calgary, which encourages a continuing rivalry between the two cities. English is the province's official language. In 2016, 76.0% of Albertans were anglophone, 1.8% were francophone and 22.2% were allophone.
