The Conservative Party of Canada is a federal political party in Canada. It was formed in 2003 by the merger of the two main right-leaning parties, the Progressive Conservative Party and the Canadian Alliance, the latter being the successor of the Western Canadian–based Reform Party. The party sits at the centre-right to the right of the Canadian political spectrum, with their federal rival, the centre to centre-left Liberal Party of Canada, positioned to their left. The Conservatives are defined as a "big tent" party, practicing "brokerage politics" and welcoming a broad variety of members, including "Red Tories" and "Blue Tories".
