Canadian Prime Minister Mark Carney’s Liberal government has moved closer to securing a parliamentary majority after another opposition lawmaker crossed the floor to join the ruling party.
Lori Idlout, a Member of Parliament from the northern territory of Nunavut representing the New Democratic Party (NDP), announced she was joining the Liberal Party of Canada after what she described as “much personal reflection.”
“At this turning point in our history, I am ready to work with Mark Carney to build a strong future for Nunavut and for all of Canada,” Idlout said in a statement released by the Liberals.
Floor crossing is permitted under Canada’s parliamentary system, which is based on the Westminster system. Such defections have occurred more than 300 times since Canadian Confederation in 1867.
Carney currently leads a minority government, but recent defections have strengthened his position in the House of Commons of Canada. Idlout’s move follows three earlier defections from members of the Conservative Party of Canada.
In February, Matt Jeneroux, a Conservative MP from Edmonton, joined the Liberal caucus. Late last year, Chris d’Entremont of Nova Scotia and Michael Ma of Ontario also crossed the floor to support Carney’s government.
Idlout, who was first elected in 2021, said she believes Canada needs “a strong and ambitious government” to address issues such as climate change, rising living costs and national sovereignty.
The move was sharply criticized by the NDP. Interim party leader Don Davies said he was “very disappointed” by the decision, arguing that MPs who switch parties should seek a renewed mandate from voters.
Opposition leader Pierre Poilievre of the Conservatives also attacked the Liberals, accusing Carney of using “backroom deals” to assemble what he called a costly majority government that voters did not approve in the last election.
Political analysts say the series of defections is unusual and reflects the shifting political landscape in Canada.
Researcher Semra Sevi from the University of Toronto said having four MPs from different parties join the governing Liberals within months is rare, calling it “extremely fortunate timing” for Carney.
Another expert, Laura Stephenson of Western University, said the Liberals’ centrist approach under Carney has broadened the party’s appeal to politicians across the political spectrum.
The government could soon reach a majority depending on the outcome of three by-elections scheduled for April 13. Two of those contests will take place in Toronto, widely considered Liberal strongholds, while the third will be held in Montreal following a razor-thin previous result that was later overturned by the Supreme Court of Canada.
If the Liberals win all three seats, they would hold 173 seats in the House of Commons, enough to secure a majority government and potentially avoid a federal election for up to three years.
