Provinces of Canada in the context of "British Columbia Interior"

A province is an administrative division within a country or state. The term derives from the ancient Roman provincia, which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term province has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city".

While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of central or federal authority, especially in Canada and Pakistan. In other countries, like China or France, provinces are the creation of central government, with very little autonomy.

The Trans-Canada Highway (French: Route Transcanadienne; abbreviated as the TCH or T-Can, or simply the Trans-Canada) is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476 kilometres (4,645 mi) across the country, one of the longest routes of its type in the world. The highway system is recognizable by its distinctive white-on-green maple leaf route markers, although there are small variations in the markers in some provinces.

While by definition the Trans-Canada Highway is a highway system that has several parallel routes throughout most of the country, the term "Trans-Canada Highway" often refers to the main route that consists of Highway 1 (British Columbia, Alberta, Saskatchewan, and Manitoba), Highways 11, 17, and 417 (Ontario), Autoroutes 40, 25, 20, and 85 and Route 185 (Quebec), Highway 2 (New Brunswick), Highways 104 and 105 (Nova Scotia), and Highway 1 (Newfoundland and Labrador). This main route starts in Victoria, British Columbia and ends in St. John's, Newfoundland and Labrador, passes through nine of the ten provinces, and connects most of the country's major cities, including Vancouver, British Columbia; Calgary, Alberta; Regina, Saskatchewan; Winnipeg, Manitoba; Ottawa, Ontario; Montreal and Quebec City, Quebec; and Fredericton, New Brunswick. One of the main route's eight other parallel routes connects to the tenth province, Prince Edward Island.

Legislative assembly is the name given in some countries to either a legislature, or to one of its houses.

The name is used by a number of countries, including member-states of the Commonwealth of Nations and other countries. It is also used by their sub-national divisions, such as the Indian states and union territories, Australian states and Canadian provinces.

Maritime Union (French: Union des Maritimes) is a proposed political union of the three Maritime provinces of Canada – New Brunswick, Nova Scotia, and Prince Edward Island – to form a single new province.

The idea has been proposed at various times throughout Canadian history, most recently in November 2012 by Stephen Greene, John D. Wallace and Mike Duffy, three Conservative Senators from the region. As of 2024, a union of the three Maritime provinces would have a population of approximately 2.1 million, becoming the fifth largest by population, out of eight remaining Canadian provinces.

The premier of Quebec (French: premier ministre du Québec [pʁəmje ministʁ dy kebɛk] (masculine) or première ministre du Québec [pʁəmjɛʁ-] [feminine]) is the first minister and head of government of the Canadian province of Quebec. The current premier of Quebec is François Legault of the Coalition Avenir Québec, sworn in on October 18, 2018, following that year's election.

The Canadian Aspen Forests and Parklands is one of 844 terrestrial ecoregions defined by One Earth. This ecoregion includes parts of the Canadian provinces of Alberta, Saskatchewan, and Manitoba, north-central and eastern (except extreme eastern) North Dakota, most of east South Dakota, and north-central Nebraska in the American Great Plains. The United States Environmental Protection Agency (EPA) defines this ecoregion as the Northern Glaciated Plains.
