The short answer
The 2 May 2011 election produced two breakthroughs at once: Stephen Harper’s Conservatives won a majority, while Jack Layton’s NDP became Official Opposition. The Orange Wave describes the NDP’s surge, especially in Quebec. It explains a transformation of the opposition rather than a transfer of the premiership to Layton.
Chronology
A timeline of the turning points
A smaller NDP caucus
The NDP wins 37 seats; Harper forms another Conservative minority.
Confidence defeat and dissolution
The government loses the House’s confidence and Parliament is dissolved for an election.
Campaign surge
Layton and the NDP gain support, particularly in Quebec.
Two parliamentary changes
Conservatives gain a majority and the NDP becomes the largest opposition party.
Layton dies
His death comes only months after the breakthrough.
The election began with a failed confidence test
Harper had governed without a Commons majority after the 2008 election. On 25 March 2011 the House adopted a non-confidence motion connected to its finding of contempt over withheld government information. Dissolution followed on 26 March, and voters went to the polls on 2 May.
The campaign therefore grew out of a parliamentary accountability dispute as well as competing economic and social programmes. It was not a separate national vote for a president. Voters elected constituency MPs, whose combined results determined the strength of the parties in the Commons.
Quebec made the NDP caucus much larger and different
The final official provincial table gives the NDP 59 of Quebec’s 75 seats. Nationally it won 103. Thus Quebec supplied a majority of the NDP caucus, and local victories in that province were central to the party’s new position.
The Bloc Québécois was left with four seats and the Liberals with 34 nationally. The shift changed who would scrutinize the government and which regional voices dominated the main opposition caucus. A party with an enlarged Quebec contingent faced a different representative task from the much smaller NDP caucus elected in 2008.
Leader appeal worked alongside agreement on values and issues
Layton’s public appeal was a prominent explanation for the surge. A published abstract by Patrick Fournier and colleagues, drawing on the Canadian Election Study and news coverage, identifies both the gap between his image and other leaders’ images and the fit between NDP positions and many Quebec voters’ preferences.
That finding supports a more useful explanation than attributing every new vote to a charismatic campaign. Voters could respond to the messenger and to policy. It also cautions against reading the result as proof that every NDP voter had adopted a permanent party identity or resolved all debates about Quebec’s place in Canada.
Popular votes and constituency victories answered different questions
Elections Canada’s rounded official table records 30.6 per cent of valid votes for the NDP nationally and 42.9 per cent in Quebec. Those figures differ from its share of seats: 103 of 308 nationally, and 59 of 75 in Quebec. Seats were won riding by riding, not allocated in direct proportion to a national or provincial vote total.
This explains how the Quebec breakthrough could be so large without the NDP receiving most of the province’s valid votes. It also explains why a strong vote total in one region could yield a different number of MPs from the same percentage spread thinly across many constituencies.
An opposition breakthrough coexisted with a Conservative majority
The final totals were Conservative 166, NDP 103, Liberal 34, Bloc Québécois four and Green one. They account for all 308 seats. With 155 seats needed for a majority in that House, the Conservative result put Harper in a stronger legislative position than before the election.
Layton’s achievement was historic within the NDP’s federal career, but Official Opposition did not confer executive power. His death on 22 August also cut short the first phase of the enlarged caucus. The election is consequently best understood as both a government majority and a reorganization of its opposition.
