42nd Canadian federal election

Background

Bob Rae was chosen as interim leader of the Liberal Party. In July 2011 Jack Layton, suffering from cancer, temporarily stepped down as leader of the NDP because of illness, indicating his intention to return for the reconvening of Parliament in September. Weeks later Layton died of cancer and was given a state funeral. In March 2012 Tom Mulcair was elected leader of the New Democratic Party. In April 2013 Justin Trudeau was elected leader of the Liberal Party. Bloc Québécois leader Daniel Paillé stepped down in December 2013 and was eventually replaced in June 2014 by Mario Beaulieu, who in turn was replaced by Duceppe in June 2015. In late 2014, MPs Jean-François Larose of the NDP and Jean-François Fortin of the Bloc formed the new political party Strength in Democracy. As set forth in the Fair Representation Act, the number of seats in the House of Commons to be contested in the 42nd Canadian federal election was 338, an increase of 30 seats from the 308 seats comprising the House of Commons of Canada of the 41st Parliament of Canada, at its dissolution.
