Liberal Party of Canada
The Liberal Party of Canada, or Parti Libéral du Canada is a Canadian federal political party. Other Liberal parties exist in all of the Canadian provinces, but only the ones in New Brunswick, Prince Edward Island, Nova Scotia and Newfoundland and Labrador are directly affiliated with the federal party as its provincial wings, with all others having since split from the federal Liberals at various times (in fact, one of those parties, the British Columbia Liberal Party, broke ties with the federal Liberals in 1987 and, after moving centre-right, succeeded long-governing conservative party the British Columbia Social Credit Party as that province's main conservative political party).
Historically, the Liberal party has been either the ruling party, or the Official Opposition. It is generally to the (far) left of the Conservative Party of Canada, yet to the right of the NDP. It is also the oldest party in Canada. The Liberal Party, and liberals in Canada are known informally as "Grits". They are opposed by the Conservative Party, New Democratic Party, Green Party of Canada and the separatist Bloc Québecois.
In the 2011 elections the Liberals were demolished by the success of the NDP. The Liberals' seat total was reduced from 77 prior to the election to a record low of 34 making them, for the first time ever, the third party in Canadian politics. Their leader at the time, Michael Ignatieff failed to win even his own riding and resigned as party leader. Bob Rae, the former NDP premier of Ontario was named interim leader until Justin Trudeau was elected leader in 2013.
The Liberal party has always supported leftist policies, although not to the levels of the NDP. Historically, the main voting points of the Liberal Party were defined by the theories of Liberal theorists. Recently, however, a plethora of new ideologies are included in the party platform, including "legalizing" marijuana, extending special "rights" to same-sex couples, increasing renewable energy resources, and increasing corporate tax to pre-conservative levels of 18% (Currently at 16.5%).
