Early politics 1910s to 1940s

Early-20th-century Calgary served as a hotbed for political activity. Historically Calgarians supported the provincial and federal conservative parties, the opposite of the Liberal-friendly City of Edmonton. However, Calgarians were sympathetic to the cause of workers and supported the development of labour organizations. In 1909, the United Farmers of Alberta (UFA) formed in Edmonton through the merger of two earlier farm organizations as a non-partisan lobbying organization to represent the interests of farmers. The UFA eventually dropped its non-partisan stance when it contested the 1921 provincial election. It was elected to form the province's first non-Liberal government. By that time Calgary was using single transferable vote (STV), a form of proportional representation, to elect its city councillors. Calgary was the first city in Canada to adopt PR for its city elections. Councillors were elected in one at-large district. Each voter cast just a single vote using a ranked transferable ballot. The UFA government elected in 1921 changed the provincial election law so that Calgary could elect its MLAs through PR as well. Calgary elected its MLAs through PR until 1956 and its councillors through PR until 1971 (although mostly using instant-runoff voting, not STV, in the 1960s).

Calgary endured a six-year recession following the First World War. The high unemployment rate from reduced manufacturing demand, compounded with servicemen returning from Europe needing work, created economic and social unrest. By 1921, over 2,000 men (representing 11 percent of the male workforce) were officially unemployed. Labour organizations began endorsing candidates for Calgary City Council in the late 1910s and were quickly successful in electing sympathetic candidates to office, including Mayor Samuel Hunter Adams in 1920. As well the Industrial Workers of the World and its sequel, the One Big Union, found much support among Calgary workers.

The city's support of labour and agricultural groups made it a natural location for the founding meeting of the Co-operative Commonwealth Federation (precursor to the New Democratic Party). The organizational meeting was held in Calgary on July 31, 1932, with attendance exceeding 1,300 people. Pat Lenihan was elected to the Calgary City Council in 1939, in part due to the use of Proportional Representation in city elections. He is the only Communist Party member elected to Calgary council. (He is the subject of the book Patrick Lenihan from Irish Rebel to Founder of Canadian Public Sector Unionism, edited by Gilbert Levine (Athabasca University Press).)

In 1922, Civic Government Association formed in opposition to the power of labour groups, endorsing its own competing slate of candidates. Labour's influence was short-lived on the City Council, with Labour as a whole failing to receive substantial support after 1924.

Calgary gained further political prominence when R. B. Bennett 's Conservative Party won the 1930 federal election and formed government and became Canada's 11th prime minister. Bennett arrived in Calgary from New Brunswick in 1897, was previously the leader of the provincial Conservative Party, advocated for Calgary as the capital of Alberta, and championed the growing city. Calgary had to wait another decade to have a sitting premier represent the city, when sitting Social Credit Premier William Aberhart moved from his Okotoks-High River to Calgary for the 1940 provincial election after his Okotoks-High River constituents began a recall campaign against him as their local MLA.
