There have been various groups in Canada that have nominated candidates under the label Labour Party or Independent Labour Party, or other variations from the 1870s until the 1960s. These were usually local or provincial groups using the Labour Party or Independent Labour Party name, backed by local labour councils made up of many union locals in a particular city, or individual trade unions. There was an attempt to create a national Canadian Labour Party in the late 1910s and in the 1920s, but these were only partly successful.
The Communist Party of Canada (CPC), formed in 1921, fulfilled some of labour's political yearnings from coast to coast, and then the Co-operative Commonwealth Federation (CCF) – Worker Farmer Socialist was formed in 1932. With organic ties to the organized labour movement, this was a labour party by definition. Prior to the CCFs formation in 1932, the Socialist Party of Canada was strong in British Columbia and in Alberta before World War I, while the Dominion Labour Party and the Canadian Labour Party were strong in Alberta through the 1920s and 1930s, and the Independent Labour Party led by J. S. Woodsworth was strong in Manitoba in the 1920s and 1930s.
An Edmonton-based Independent Labour Party ran candidates in the 1921 Alberta general election. It was independent in the sense that it was separate from the Edmonton Labour Council, which was dominated by international craft unions. Later, many of its proponents joined the CPC. A number of local Labour parties and clubs participated in the formation of the CPC in 1921. The Independent Labour Party (Manitoba), the Canadian Labour Party, the Dominion Labour Party, and other labour groups helped found the CCF in 1932.
The first Labour Member of Parliament (MP) was Arthur Puttee who founded the Winnipeg Labour Party, and was elected to the House of Commons from Winnipeg, Manitoba in a 1900 by-election and kept his seat at the 1900 federal election held later the same year. Other MPs elected under the Labour or Independent Labour label include:
MacInnis, Heaps and Woodsworth joined the Ginger Group of left wing MPs prior to forming the CCF. Alberta Labour MPs Irvine and Shaw, and its UFA MPs, also were in the Ginger Group.
Four Independent Labour Party (ILP) MLAs and one Farmer-Labour MLA (all but one from Cape Breton) were elected to the Nova Scotia House of Assembly in the 1920 general election. They joined with six United Farmer MLAs to form the official opposition in the legislature with United Farmer MLA Daniel G. MacKenzie as leader. All the United Farmer and ILP MLAs were defeated in the 1925 general election. A single Labour MLA, Archibald Terris was elected in 1928 representing Cumberland County; he did not run for re-election in 1933.
The Nova Scotia Co-operative Commonwealth Federation began running candidates with the 1933 general election and became the New Democratic Party in 1961. In 1982 the Cape Breton Labour Party was formed by MLA Paul MacEwan after he was expelled from the NDP. It ran 14 candidates in the 1984 general election but MacEwan was the only candidate to win the seat. The party soon dissolved and MacEwan was re-elected in 1988 as an independent before joining the Nova Scotia Liberal Party in 1990.
A number of members of the Legislative Assembly of Quebec were labelled Parti ouvrier (Labour Party) from the 1890 election until the 1931 election. They represented predominantly labour-class neighbourhoods in Montreal and Quebec City and consisted of:
A number of Labour MLAs were elected in the 1919 provincial election which led to the formation of a United Farmers of Ontario-Labour coalition government. Labour MLAs included:
The last Labour MLA elected to the legislature was Earl Hutchinson who was elected in Kenora in 1929 and re-elected in 1934. He agreed to resign shortly after his re-election to allow former Labour MLA Peter Heenan to seek the Kenora seat in a by-election so that he could be appointed to the provincial cabinet by the newly elected Liberal government of Mitchell Hepburn. Hutchinson accepted an appointment by Hepburn to the post of vice-chairman of the Workmen's Compensation Board shortly after leaving politics.
The Ontario Co-operative Commonwealth Federation was formed in 1932 with the support of a number of Independent Labour Party clubs and won its first seat in the 1934 provincial election, Samuel Lawrence in Hamilton East.
As well, Alberta Labour candidates ran with some success at the civic level in Edmonton, Calgary, Medicine Hat, and Lethbridge and coal-mining towns, such as Drumheller and Blairmore (which even elected a Communist Party-dominated town council in the 1930s).
In 1917, the Trades and Labour Congress (TLC) national convention in Toronto passed a resolution calling on provincial labour federations to establish a political party which would unite socialist and labour parties in the province and eventually form a national party. A Canadian Labour Party was formed, and endorsed several candidates in the 1917 federal election. The leadership of the TLC changed in 1918, however, and the new leaders favoured the "non-partisan" approach of American Federation of Labor leader Samuel Gompers. The CLP was abandoned, as such.
Between 1920 and 1926, provincial parties (or provincial wings of national bodies) were founded in British Columbia, Manitoba, Alberta, Ontario and Quebec.
The Federated Labour Party was created by the British Columbia Federation of Labour in 1920, absorbing the Social Democratic Party and part of the Socialist Party of Canada.
From 1906 to 1909, there was a Canadian Labour Party of B.C. (CLP(BC)). This party was a split from and rival to a group calling itself the Independent Labour Party.
A later Independent Labour Party was organized in British Columbia in 1926 by the Federated Labour Party and Canadian Labour Party (B.C. section) branches. In 1928, it severed its CLP(BC) connections. In 1931, it reorganized, and was renamed the Independent Labour Party (Socialist). The following year it became the Socialist Party of Canada.
In Manitoba, a Dominion Labour Party (DLP) had been created in 1918. This was a reformist party, although more explicitly socialist than the previous such organizations in the province (see Winnipeg Labour Party, Manitoba Independent Labour Party, Manitoba Labour Party, Labour Representation Committee). The DLP elected several members to the Legislative Assembly of Manitoba in 1920. It was taken over by rightist elements affiliated with the American Federation of Labour later in the year, and most of the MLAs formed a new Independent Labour Party.
The Alberta wing of the Dominion Labour Party was formed in 1920. Unlike the Manitoba DLP, radicals did not lose control of this group. and it was not split by a radical-versus-reformist schism. It remained a viable organization until the 1930s, in an alliance with the Canadian Labour Party (see below). It elected a few MPs in Calgary in the 1921, 1925, 1926 and 1930 federal elections.
In Saskatchewan, the Independent Labour Party was formed in 1931 and led by M.J. Coldwell, It merged with the United Farmers of Canada (Saskatchewan Section) to form the Farmer-Labour Group in 1932. This group became the Saskatchewan CCF in 1934.
The Ontario Labour Party was created in 1922, led by James Simpson of the Independent Labour Party, and the Reverend A. E. Smith, later of the Communist Party of Canada.
In 1921, Simpson also revived the Canadian Labour Party. The CLP was intended to be an umbrella organization for the various labour parties throughout the country. It formed alliances with the Federated Labour Party, Ontario Labour Party, Dominion Labour Party and other groups, including local labour councils, (although not with the Manitoba ILP). The Alberta wing of the CLP was founded in 1922. Between 1922 and 1924, the provincial and city branches of the Workers Party of Canada (the legal face of the Communist Party of Canada) also joined the CLP. It was never a strong central organization, however, and never elected a candidate at the national level. The CLP ceased to exist in most parts of the country after 1929, when the Communists withdrew. In Alberta, the CLP survived until 1942, in arms-length alliance with the Alberta Co-operative Commonwealth Federation after 1932.
At various times in political history of Canada and of Ontario, candidates have sought election as Liberal-Labour candidates. (Please see linked article.)
Conservative Labour was the label used by Conservative Party of Canada politician Henry Buckingham Witton as a candidate in Hamilton, Ontario from 1872 to 1875. Witton may have added "Labour" to the Conservative Party name because Hamilton is a largely industrial city. The first workingman ever to sit in parliament in Canada, Witton was elected largely on the strength of the Hamilton labour movement. Indeed, his candidacy was aided by workers throughout southern Ontario, as can be seen by the very supportive coverage he received in the (Toronto) Ontario Workman.
Witton was employed as a master painter at the Great Western Railway Shops when he was elected in the 1872 federal election, and sat with the Conservative caucus of Sir John A. Macdonald before being defeated in the 1874 election. He ran again in an 1875 by-election but was again defeated.
Across Canada, labour and the farmers movements, particularly the United Farmers, formed alliances, and often ran joint candidates. The Progressive Party of Canada was effectively a coalition of farmer and labour groups.
John Wilfred Kennedy, a farmer, was elected as a United Farmers of Ontario-Labour MP for Glengarry and Stormont in a 1919 by-election. He was re-elected as a Progressive MP in the 1921 federal election and was defeated in 1925.
Agnes Macphail, who was first elected to the House of Commons as a Progressive, was re-elected in 1935 as a UFO-Labour candidate before being defeated in 1940. She was a supporter of the Co-operative Commonwealth Federation, but ran as UFO-Labour because the UFO, of which she was a member, had disaffiliated from the CCF in 1934 after a brief association.
A small number of candidates ran under the "Farmer-Labour" banner in federal elections of the 1930s and 1940s, although there was no organized party. None of these candidates ever won election to the House of Commons. One of these candidates was Beatrice Brigden who was the first Farmer-Labour candidate from Brandon, Manitoba. She ran in 1930, but was defeated by David Wilson Beaubier.  Farmer-Labour co-operation would be enshrined as a guiding principle of the Co-operative Commonwealth Federation, founded in 1932, and of its successor, the NDP.
Labour and Independent Labour Party Members of the Legislative Assembly (MLAs) joined with members of the United Farmers of Ontario to form a Farmer-Labour coalition government from 1919 to 1923 with E. C. Drury as Premier of Ontario.
The Labour MLAs elected in 1921 (six at the most at any one time) worked with the United Farmers of Alberta government during its 14 years in power, and one even sat as a cabinet minister in the UFA cabinet for five years. Alberta's Labour MPs and its UFA MPs were both active in the Ginger Group.
The United Farmers and the Independent Labour Party merged to form the Farmer-Labour Group in 1932. In the 1934 provincial election, the Farmer-Labour Group won almost 24% of the popular vote and 5 seats in the Legislative Assembly of Saskatchewan, where it became the official opposition to the Liberal government. After the election, it became the Saskatchewan section of the CCF.
Eleven United Farmers and Labour candidates were elected to the Nova Scotia Legislative Assembly in the 1920 general election forming the official opposition in the province.
In the 1920 provincial election nine United Farmers candidates and two Farmer-Labour candidates  were elected to the Legislature. They sat together and allowed the incumbent Liberals to maintain confidence in a minority government situation. None of the MLAs were re-elected in the 1925 election.
The Progressive Party of Canada, formally the National Progressive Party, was a federal-level political party in Canada in the 1920s until 1930. It was linked with the provincial United Farmers parties in several provinces, and it spawned the Progressive Party of Saskatchewan, and the Progressive Party of Manitoba, which formed the government of that province. The Progressive Party was part of the farmers' political movement that included federal and provincial Progressive and United Farmers' parties.
The United Farmers of Ontario (UFO) was an agrarian and populist provincial political party in Ontario, Canada. It was the Ontario provincial branch of the United Farmers movement of the early part of the 20th century.
Liberal-Progressive was a label used by a number of candidates in Canadian elections between 1925 and 1953. In federal and Ontario politics, there was no Liberal-Progressive party: it was an alliance between two parties. In Manitoba, a party existed with this name.
The United Farmers of Alberta (UFA) is an association of Alberta farmers that has served different roles in its 100-year history – as a lobby group, a successful political party, and as a farm-supply retail chain. As a political party, it formed the government of Alberta from 1921 to 1935.
Frederick John Dixon was a Manitoba politician, and was for several years the dominant figure in the province's mainstream labour and Henry George Single Tax Georgist movements. Also a proponent of proportional representation, he served as MLA in the Manitoba Legislature from 1914 to 1923.
The Independent Labour Party was the leading social-democratic party in the Canadian province of Manitoba prior to the emergence of the Co-operative Commonwealth Federation. Several of its candidates were elected to the Legislative Assembly of Manitoba and it counted federal Members of Parliament J. S. Woodsworth and A. A. Heaps among its members.
Seymour James Farmer was a politician in Manitoba, Canada. He served as Winnipeg MLA from 1922 to 1949. During this time he also served as mayor of Winnipeg 1923-1924 and later as city councillor in the late 1920s and in the 1930s. He was the leader of the Manitoba Co-operative Commonwealth Federation from 1935 to 1947. He served as a cabinet minister in Manitoba's World War I coalition government.
The Co-operative Commonwealth Federation (Manitoba) (CCF), known informally as the Manitoba CCF, was a provincial branch of the national Canadian party by the same name. The national CCF was the dominant social-democratic party in Canada from the 1930s to the early 1960s, when it merged with the labour movement to become the New Democratic Party. The Manitoba CCF, created in 1932, played the same role at the provincial level.
The Canadian Labour Party (CLP) was an early, unsuccessful attempt at creating a national labour party in Canada. Although it ran candidates in the federal elections of 1917, 1921, 1925, and 1926, it never succeeded in its goal of providing a national forum for the Canadian labour movement. In most provinces, the CLP ceased to exist after 1928–1929.
The 1926 Alberta general election was held on June 28, 1926, to elect members of the Legislative Assembly of Alberta. The United Farmers of Alberta government that had first been elected in 1921 was re-elected, taking a majority of the seats in the Alberta Legislature. Herbert Greenfield had resigned as United Farmers leader and premier, and John E. Brownlee led the UFA to this second election victory, increasing the UFA's number of seats.
The 1936 Manitoba general election was held July 27, 1936 to elect Members of the Legislative Assembly of the Province of Manitoba, Canada. The Liberal-Progressives won minority government in this election, taking 23 seats out of 53 and 35 percent of the vote.
Joseph Tweed Shaw was a Canadian politician. He served in the House of Commons of Canada from 1921 to 1925 as an independent Labour Member of Parliament (MP), and later became an MLA and leader of the Alberta Liberal Party.
The Progressive Party of Saskatchewan was a provincial section of the Progressive Party of Canada and was active from the 1920s to the mid-1930s. The Progressives were an agrarian, social democratic political movement. It was originally dedicated to political and economic reform; it also challenged economic policies that favoured the financial and industrial interests in Central Canada over agrarian interests. Like its federal counterpart it favoured free trade over protectionism.
Frederic James White was a provincial level politician and labour activist in Canada. He was a Labour Party MLA from 1921 to 1935 representing Calgary.
The Dominion Labor Party (Alberta) was a minor political party. It was founded on June 11, 1918 when Edmonton's Labour Representation League renamed itself the Alberta wing of the DLP. Its executive included Mr. Marshall, Mr. Mercer, Mr. Dan Knott, later mayor of the city, White, Findlay and Farmilo, and Elmer Roper, later mayor Edmonton.
