In contrast with the political party systems of many nations, Canadian political parties at the federal level are often only loosely connected with parties at the provincial level, despite having similar names. One exception is the New Democratic Party, which is organizationally integrated with most of its provincial counterparts including a shared membership.
These are all of the political parties registered with Elections Canada as of March 2017.
The Canadian Senate has two additional parliamentary groups, the Senate Liberal Caucus (consisting of senators who are members of the Liberal Party but not affiliated with the Liberal Party of Canada) and the Independent Senators Group (a group which organizes and funds non-partisan senators). Both are unaffiliated with other Canadian political parties, are not registered with Elections Canada, and do not run candidates in Canadian federal elections. Conservative senators remain formally affiliated with the Conservative Party of Canada.

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. From 1938 until 1943 its candidates ran under the banner Unity or United Progressive. In 1943 it adopted the name Labor-Progressive Party. It won one seat under this name 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.
Labour Party
Labour Party candidates ran under numerous different designations:
Conservative-Labour (1872-1875)
Farmer Labour
Farmer-United Labour
Labour-Farmer
Liberal-Labour (1926-1968)
National Labour (1940)
United Farmers-Labour (1920)
United Farmers of Ontario-Labour (1919-1940)
Liberal Party
During Robert Borden's coalition government of 1917-1920, the Liberal Party of Canada split into two groups: the Liberal–Unionist who supported the coalition and the Laurier Liberals who opposed it.
Liberal-Progressive
Some Liberal-Progressive candidates used the designations:
Liberal-Labour-Progressive or
National Liberal Progressive.
New Democratic Party
The Co-operative Commonwealth Federation used the name New Party from 1958-1961 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.
Party for Accountability, Competency and Transparency
The Party for Accountability, Competency and Transparency was founded as the Online Party of Canada.
Progressive 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.
Progressive Party and United Farmers
Some candidates for the Progressive Party of Canada used United Farmer designations:
Farmer (1925 & 1930),
United Farmers of Canada,
United Farmers of Alberta, or
United Farmers of Ontario.
Rhinoceros Party
The first Rhinoceros Party disbanded in 1993. When it was revived in 2006 it used the name "neorhino.ca". The party changed its name to Rhinoceros Party in 2010.
Social Credit Party and Ralliement créditiste
Some Ralliement créditiste used the name Ralliement des créditistes from 1963 to 1967. One candidate used the designation Candidats des électeurs in 1957 and 1958.
In the 1940 election, 17 candidates ran jointly with the Social Credit Party under the name New Democracy.
