About the election Short description of the context and results of the election.
The Liberal Party, led by Mr. Justin Trudeau - a son of former Prime Minister Pierre Trudeau - won an outright majority in the enlarged 338-member House of Commons, thereby denying a fourth term to Prime Minister Stephen Harper and his Conservative Party. The Liberal Party - which was only the third largest party in the outgoing legislature - increased its share of seats from 11% to 54%. On the contrary, the New Democratic Party (NDP), led by Mr. Thomas Mulcair, saw its share of seats reduced from 33% to 13% and came in third. A record 10 indigenous people entered the House of Commons, up from seven in the 2011 elections. Mr. Harper conceded defeat and resigned as party leader. The 43-year-old new Prime Minister immediately announced that Canada would withdraw its fighter jets from the US-led mission against Islamic State in Iraq and Syria. His Cabinet, composed equally of men and women, was sworn in on 4 November.
 The 2015 elections saw a record 78-day campaigning period , the longest in Canada since 1872. During the election campaign, the major parties focused on the economy, taxation and the budget. Prime Minister Harper promised low taxes, balanced budgets and more austerity. Liberal leader Trudeau said he would run a budget deficit to invest more in the country's economy.
