Canadian Confederation was the process by which three British North American provinces—the Province of Canada, Nova Scotia, and New Brunswick—were united into one federation called the Dominion of Canada, on July 1, 1867. Upon Confederation, Canada consisted of four provinces: Ontario and Quebec, which had been split out from the Province of Canada, and the provinces of Nova Scotia and New Brunswick. Over the years since Confederation, Canada has seen numerous territorial changes and expansions, resulting in the current number of ten provinces and three territories.

British North America comprised the colonial territories of the British Empire in North America from 1783 onwards. English colonisation of North America began in the 16th century in Newfoundland, then further south at Roanoke and Jamestown, Virginia, and more substantially with the founding of the Thirteen Colonies along the Atlantic coast of North America.
