Hours after conceding defeat on election night, incumbent Prime Minister Stephen Harper resigned as leader of the
Conservative Party, though he announced his intention to remain in the new parliament as a backbencher after being elected in the riding of
Calgary Heritage. The Conservative caucus met on November 5, 2015, and elected former health minister and Alberta MP
Rona Ambrose as interim leader of the party, and hence, interim
Leader of the Official Opposition. The next
Conservative Party of Canada leadership election was held on May 27, 2017. Following his swearing in on November 4, 2015, Prime Minister Justin Trudeau announced that parliament would reconvene on December 3, 2015, with the
Speech from the Throne to follow on December 4.
Commentary In the aftermath of the 2011 election, many pundits had characterized it as a
realigning election.
Lawrence Martin, commentator for
The Globe and Mail said, "Harper has completed a remarkable reconstruction of a Canadian political landscape that endured for more than a century. The realignment saw both old parties of the moderate middle, the Progressive Conservatives and the Liberals, either eliminated or marginalized."
Andrew Coyne, writing in ''Maclean's'', said the election marked "an unprecedented realignment of Canadian politics" as "the Conservatives are now in a position to replace the Liberals as the
natural governing party in Canada." Despite the grim outlook and poor early poll numbers, when the 2015 election was held, the Liberals under Trudeau made an unprecedented comeback. Gaining 148 seats, they won a majority government for the first time since 2000. Chantal Hébert, writing in the
Toronto Star, claimed the comeback was "headed straight for the history books" and that Harper's name would "forever be joined with that of his Liberal nemesis in Canada's electoral annals". Spencer McKay, writing for the
National Post, suggested that "maybe we've witnessed a revival of Canada's 'natural governing party'".
