Canada (pronounced /ˈkænədə/) is a country occupying most of northern North America, extending from the Atlantic Ocean in the east to thePacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area and its common borderwith the United States to the south and northwest is the longest in the world.
The land occupied by Canada was inhabited for millennia by various groups of Aboriginal people. Beginning in the late 15th century, British andFrench expeditions explored, and later settled along, the Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federaldominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament.A federation comprising ten provinces and three territories, Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II as its head of state. It is a bilingual and multicultural country, with both English and French as official languages both at the federal level and in the province of New Brunswick. One of the world's highly developed countries, Canada has a diversified economy that is reliant upon its abundant natural resources and upon trade—particularly with the United States, with which Canada has had a long and complex relationship. It is a member of the G8, G-20, NATO, OECD, WTO, Commonwealth, Francophonie, OAS, APEC, and UN.
