Canada is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west, and northward into the Arctic Ocean. Spanning over 9.9 million square kilometres, Canada is the world's second-largest country by total area, and its common border with the United States is the longest land border in the world.
The land that is now Canada has been inhabited for millennia by various groups of Aboriginal peoples. Beginning in the late 15th century, British and French expeditions explored, and later settled, along the region's 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 federal dominion 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 Balfour Declaration of 1926 and reaffirmed by the Statute of Westminster of 1931, which declared self-governing dominions within the British Empire to be equal. The Canada Act of 1982 finally severed the vestiges of legal dependence on the British Parliament.
Canada is a federal state that is governed as a parliamentary democracy and a constitutional monarchy with Queen Elizabeth II as its head of state. It is a bilingual nation with both English and French as official languages at the federal level. One of the world's most 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 G7, G8, G20, NATO, OECD, WTO, Commonwealth of Nations, Francophonie, OAS, APEC, and UN. With the sixth-highest Human Development Index globally, Canada has one of the highest standards of living in the world. For more information visit Wikipedia.
