St. John's served as the capital city of the Colony of Newfoundland and the Dominion of Newfoundland before Newfoundland became Canada's tenth province in 1949. The city now serves as the capital of Newfoundland and Labrador, therefore the provincial legislature is located in the city. The Confederation Building, located on Confederation Hill, is home to the House of Assembly along with the offices for the Members of the House of Assembly (MHAs) and Ministers. The city is represented by ten MHAs, four who are members of the governing Progressive Conservative Party, three that belong to the New Democratic Party (NDP), and three that belong to the Liberal Party. Lorraine Michael, leader of the NDP since 2006, represents the district of Signal Hill-Quidi Vidi.
