Workers' Communist Party of Canada, 1972–1980 Pre-confederation political parties Reform Party (pre-Confederation) Name changes Communist Party The Communist Party of Canada changed its name multiple times in its history. It was founded as the Communist Party of Canada in 1921. It was underground until 1924, and founded a public face, Workers' Party of Canada, from 1922 until 1924 when the Communist Party was legalized. From 1938 until 1943 its candidates ran under the banner Unity or United Progressive, and won one seat. The Communist Party was again banned in 1940, but from 1943 operated under the name Labor-Progressive Party. It won one seat under this name in a 1943 by-election, which it retained in 1945. In 1959 it reverted to the name Communist Party of Canada and has kept that name to the present. The Marxist–Leninist Party of Canada unofficially uses the name "Communist Party of Canada (Marxist–Leninist)", but Elections Canada does not allow it to be registered by that name because of potential confusion with the Communist Party of Canada.

New Democratic Party The Co-operative Commonwealth Federation used the name New Party from 1958 to 1961 while it was transitioning to become the New Democratic Party. In French, the party used a literal translation of its name, Fédération du Commonwealth Coopératif, from until 1955. Conservative Party The first Conservative Party used several different names during its existence: Liberal-Conservative Party (some MPs until 1911), Unionist Party (1917–1921), National Liberal and Conservative Party (1920–1921), National Government (1940), Progressive Conservative Party (1942–2003) The second (and current) Conservative Party of Canada was a merger of the Canadian Alliance and the Progressive Conservative Party.
