Overview

Canada was created as a self-governing dominion by Confederation on 1 July 1867, when the British North America Act (British statute) united three colonies — the Province of Canada (split into Ontario and Quebec), Nova Scotia, and New Brunswick — into a single federal Dominion within the British Empire. Its first prime minister was Sir John A. Macdonald, a chief architect of Confederation who pursued a "National Policy" of protective tariffs, western settlement, and the transcontinental Canadian Pacific Railway (completed 1885), which bound the country together. The federation expanded to a continental nation of ten provinces and three territories, absorbing Rupert's Land, Manitoba (1870), British Columbia (1871), and eventually Newfoundland (1949).

History

Canada evolved gradually from colony to fully sovereign state. Its contributions in the First World War — especially the Battle of Vimy Ridge (1917) — fostered national identity and won it a distinct seat at the peace table. The Statute of Westminster (1931) granted legislative independence from Britain, and full constitutional autonomy came with the patriation of the Constitution in 1982 under Prime Minister Pierre Trudeau, which added the Canadian Charter of Rights and Freedoms. Enduring national themes include the accommodation of French-speaking Quebec (and two referenda on Quebec independence, 1980 and 1995, both narrowly defeated), official bilingualism and multiculturalism, and, increasingly, reconciliation with Indigenous peoples.

Later history and present status

Canada is a federal parliamentary constitutional monarchy under King Charles III (represented by a governor general), with its capital at Ottawa. Notable prime ministers include Macdonald, Wilfrid Laurier, William Lyon Mackenzie King, Lester Pearson (who introduced universal health care and the maple-leaf flag), and the two Trudeaus. Following the resignation of Justin Trudeau, the economist and former central banker Mark Carney became Liberal leader and prime minister in March 2025, and led the Liberals to victory in the April 2025 federal election, strengthening his hold to a majority government by April 2026 — a surge widely attributed to a wave of Canadian nationalism amid a trade conflict and annexation rhetoric from U.S. President Donald Trump.
