William Lyon Mackenzie King in the context of "Lester B. Pearson"

The Balfour Declaration of 1926 was issued by the 1926 Imperial Conference of British Empire leaders in London. It was named after Arthur Balfour, who was Lord President of the Council. It declared the United Kingdom and the Dominions to be:

The Inter-Imperial Relations Committee, chaired by Balfour, drew up the document preparatory to its unanimous approval by the imperial prime ministers on 15 November 1926. It was first proposed by South African Prime Minister J. B. M. Hertzog and Canadian Prime Minister William Lyon Mackenzie King.

Imperial Conferences (Colonial Conferences before 1907) were periodic gatherings of government leaders from the self-governing colonies and dominions of the British Empire between 1887 and 1937, before the establishment of regular Meetings of Commonwealth Prime Ministers in 1944. They were held in 1887, 1894, 1897, 1902, 1907, 1911, 1921, 1923, 1926, 1930, 1932 and 1937.

All the conferences were held in London, the seat of the Empire, except for the 1894 and 1932 conferences which were held in Ottawa, the capital of the senior Dominion of the Crown. The 1907 conference changed the name of the meetings to Imperial Conferences and agreed that the meetings should henceforth be regular rather than taking place while overseas statesmen were visiting London for royal occasions (e.g. jubilees and coronations).

The premierships of Pierre Trudeau occurred from April 20, 1968, to June 4, 1979, and from March 3, 1980, to June 30, 1984. Pierre Trudeau was sworn in as Prime Minister of Canada two weeks after he succeeded Prime Minister Lester B. Pearson as leader of the Liberal Party in the 1968 leadership election.

Trudeau led his Liberals to win a comfortable majority government in the subsequent 1968 federal election. In the 1972 federal election, Trudeau's Liberals were reduced to a minority government, though won a second majority in 1974. In the 1979 federal election, Trudeau's Liberals lost power to a Progressive Conservative led by Joe Clark, who formed a minority government. The PC government collapsed in a vote of non-confidence, triggering the 1980 federal election in which Trudeau's Liberals won a third majority. Trudeau is the most recent prime minister to win four elections and to serve two non-consecutive terms. His tenure of 15 years and 164 days makes him Canada's third-longest-serving prime minister, behind John A. Macdonald and William Lyon Mackenzie King.

Banknotes of the Canadian dollar are the banknotes or bills (in common lexicon) of Canada, denominated in Canadian dollars (CAD, C$, or $ locally). Currently, they are issued in $5, $10, $20, $50, and $100 denominations. All current notes are issued by the Bank of Canada, which released its first series of notes in 1935. The Bank of Canada has contracted the Canadian Bank Note Company to produce the Canadian notes since then. The current series of polymer banknotes were introduced into circulation between November 2011 and November 2013. Banknotes issued in Canada can be viewed at the Bank of Canada Museum in Ottawa.
