Progressive Conservative Party of Canada

The Progressive Conservative Party of Canada (PC) (Parti progressiste-conservateur du Canada) (1867–2003) was a Canadian political party with a centre-right stance on economic issues and a centrist stance on social issues. The party was formed in 1867 and became Canada's first governing party under Sir John A. Macdonald, and for years was either the governing party or the largest opposition party. In 2003, the party membership voted to dissolve the party and join the new Conservative Party of Canada being formed with the members of the Canadian Alliance.

After 2003, several members of the Senate of Canada who opposed the merger continued to sit as members of a "Progressive Conservative" caucus, and the conservative parties in most Canadian provinces still use the Progressive Conservative name. Some PC Party members formed the new Progressive Canadian Party, which has attracted only marginal support.

Canada's first prime minister, Sir John A. Macdonald, was originally a member of the Conservative or "Blue" Party. But in advance of confederation in 1867, the Conservative Party took in a large number of right-wing leaning members who defected from the Liberal or "Red" Party. Thereafter, the Conservative Party was the "Liberal-Conservative" (in French, "Libéral-Conservateur") Party until the turn of the twentieth century.

The party suffered a decade-long decline following the 1993 federal election, and was formally dissolved on December 7, 2003, when it merged with the Canadian Alliance to form the new Conservative Party. The Progressive Conservative caucus last officially met in early 2004.
