This is a list of Canada's 308 electoral districts (also known as ridings in Canadian English) as defined by the 2003 Representation Order, which came into effect on May 23, 2004.
Four ridings established by the British North America Act in 1867 are still in existence: Beauce, Halifax, Shefford, and Simcoe North.
Canadians elected members for each electoral district in the 2006 federal election. On November 14, 2007, the government of Canada announced a bill that would see the creation of 22 new ridings - ten in Ontario, seven in British Columbia and five in Alberta.[1] The new districts would take effect in 2014, and apply to all subsequent elections.
