Nova Scotia is a parliamentary democracy. Its unicameral legislature, the Nova Scotia House of Assembly, consists of fifty-one members. As Canada's head of state, Queen Elizabeth II is the head of Nova Scotia's chief executive government. Her duties in Nova Scotia are carried out by the Lieutenant-Governor, John James Grant. The government is headed by the Premier, Stephen McNeil, who took office October 22, 2013. Halifax is home to the House of Assembly and Lieutenant-Governor.
Nova Scotia elected minority governments in the 1998, 2003 and 2006 elections. The Progressive Conservative government of John Hamm, and later Rodney MacDonald, required the support of the New Democratic Party or Liberal Party after the election in 2003.
The province's revenue comes mainly from the taxation of personal and corporate income, although taxes on tobacco and alcohol, its stake in the Atlantic Lottery Corporation, and oil and gas royalties are also significant. In 2006/07, the Province passed a budget of $6.9 billion, with a projected $72 million surplus. Federal equalization payments account for $1.385 billion, or 20.07% of the provincial revenue. While Nova Scotians have enjoyed balanced budgets for several years, the accumulated debt exceeds $12 billion (including forecasts of future liability, such as pensions and environmental cleanups), resulting in slightly over $897 million in debt servicing payments, or 12.67% of expenses. The province participates in the HST, a blended sales tax collected by the federal government using the GST tax system.
