Premier of Manitoba in the context of Executive Council of Manitoba

The Progressive Conservative Party of Canada (PC; French: Parti progressiste-conservateur du Canada) was a centre to centre-right federal political party in Canada that existed from 1942 to 2003.

From Canadian Confederation in 1867 until 1942, the original Conservative Party of Canada participated in numerous governments and had multiple names. In 1942, its name was changed to the Progressive Conservative Party under the request of newly elected party leader Premier John Bracken of Manitoba, a former member of the Progressive Party of Manitoba. In the 1957 federal election, John Diefenbaker carried the party to their first victory in 27 years and the following year, led the party to the largest federal electoral landslide in history. During his tenure, human rights initiatives were achieved, most notably the Bill of Rights. In the 1963 federal election, the party lost power and would not regain it until 1979, when Joe Clark led the party to a minority government victory. The party lost power just nine months later and in 1983, Clark lost his leadership role to Brian Mulroney, who helped the PC Party gain popularity in Quebec. Mulroney won back-to-back majority governments in 1984 and 1988, and during his tenure, major economic reforms such as the North American Free Trade Agreement and the goods and services tax (GST) were introduced.

John Bracken PC (22 June 1883 – 18 March 1969) was a Canadian agronomist and politician who was the 11th and longest-serving premier of Manitoba (1922–1943) and later the leader of the Progressive Conservative Party of Canada (1942–1948).

Bracken was born in Ontario, and was a professor of animal husbandry at the University of Saskatchewan before moving to Manitoba in 1920. A political outsider, he was named leader of the Progressive Party of Manitoba following its upset victory in the 1922 Manitoba general election. During his tenure as premier of Manitoba, he implemented policies dominated by rural interests and opposed organized labour. He oversaw the creation of a universal pension, the provincial income tax, and reductions in spending on health, education and welfare as well as the replacement of the first past the post voting system with alternative voting. He pursued development by promoting staple industries such as mining, timber and fishing. After leading the Progressive Party to a second consecutive majority in the 1927 election, he merged the Progressive Party with the Liberal Party of Manitoba to form the Liberal-Progressive Party in 1932. He led the Liberal-Progressive Party to consecutive victories in elections in 1932, 1936 and 1941, winning majority governments in all but the 1936 election.
