The Canadian Alliance (French:Alliance canadienne), formally the Canadian Reform Conservative Alliance (French:Alliance réformiste-conservatrice canadienne), was a conservative and right-wing populist federal political party in Canada that existed from 2000 to 2003. The party was the successor to the Reform Party of Canada and inherited its position as the Official Opposition in the House of Commons and held it throughout its existence. The party supported policies that were both fiscally and socially conservative, seeking reduced government spending on social programs and reductions in taxation.
