Flag of the Alberta province, Canada

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 (255,541 square miles), 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. Alberta's economy is advanced, open, market-based, and chraacterised by a highly educated workforce, strong institutions and property rights, and sophisticated financial markets. The service sector employs 80% of Albertans, in fields like healthcare, education, professional services, retail, tourism and financial services. The industrial base includes manufacturing, construction, and agriculture (10%, 5%, and 2% of employment respectively), while the knowledge economy includes about 3000 tech companies employing an estimated 60,000 people, mainly in Calgary and Edmonton. The energy sector employs 5% of Albertans but significantly impacts exports and GDP. Alberta's exports, primarily US-bound, consist of 70% oil and gas, 13% food products, and 12% industrial products. Oil and gas are culturally influential, having shaped politics, generated "striking it rich" narratives, and created boom-and-bust cycles. In 2023, Alberta's output was $350 billion, 15% of Canada's GDP. Until the 1930s, Alberta's political landscape consisted of two major parties: the centre-left Liberals and the agrarian United Farmers of Alberta. Today, Alberta is generally perceived as a conservative province. The right-wing Social Credit Party held office continually from 1935 to 1971 before the centre-right Progressive Conservatives held office continually from 1971 to 2015, the latter being the longest unbroken run in government at the provincial or federal level in Canadian history. Since before it became part of Canada, Alberta has been home to several First Nations, such as Plains Indians and Woodland Cree. It was historically also a territory used by fur traders of the rival companies Hudson's Bay Company and North West Company. The Dominion of Canada bought the lands that would become Alberta as part of the NWT in 1870. From the late 1800s to the early 1900s, many immigrants arrived in an effort to prevent the prairies from being annexed by the United States. Growing wheat and cattle ranching became very profitable during this period. In 1905, the Alberta Act was passed, creating the province of Alberta. Massive oil reserves were discovered in 1947. The exploitation of oil sands began in 1967. Alberta is renowned for its natural beauty and is home to important nature reserves. It is also well known as a rich source of fossils. It is home to six UNESCO-designated World Heritage Sites: the Canadian Rocky Mountain Parks, Dinosaur Provincial Park, Head-Smashed-In Buffalo Jump, Waterton-Glacier International Peace Park, Wood Buffalo National Park and Writing-on-Stone Provincial Park. Other popular sites include Banff National Park, Elk Island National Park, Jasper National Park, Waterton Lakes National Park, and Drumheller.
