On July 1, 1867, the British North Americas Act created the Dominion of Canada as a federation of four provinces. This event is known as the Confederation of Canada. The four original provinces were created from the former British colonies of Nova Scotia, New Brunswick and the Province of Canada, which was divided into the provinces of Quebec and Ontario. Canada's boundaries have been extended since 1867. The country now consists of 10 provinces and three territories.
On June 20, 1868, Canada's Governor General proclaimed that Canadians should celebrate the anniversary of the confederation. July 1 became a statutory holiday, known as Dominion Day, in 1879. However, no official celebrations were held until the 50th anniversary in 1917 and the 60th anniversary in 1927. After World War II, Dominion Day was celebrated more frequently and more events were organized by the national government. After the centenary of the confederation in 1967, Dominion Day events became more widespread. July 1 became popularly known as Canada Day. The date was also officially known as Canada Day from 1983 onwards.
