Canadian prime minister Mark Carney has secured a parliamentary majority for his Liberal government, CBC News reported. The victory will help him push through a legislative agenda he says is needed for an increasingly divided geopolitical world.

Three special elections were held on Monday in Ontario and Quebec, with two in districts – known as ridings – that have long voted Liberal.

The party has secured the riding of University-Rosedale, CBC News said. The results of the other two elections were still being counted. The win takes Carney’s Liberals to 172 seats in the 343-seat House of Commons.

The University-Rosedale seat was previously held by former deputy prime minister Chrystia Freeland, who resigned after being appointed as economic development adviser in Ukraine.

Carney has said a majority would help him deal more effectively with the trade war with the US started by president Donald Trump.

“He will be able to pass legislation without having to go to the opposition to secure enough votes,” said Andrew McDougall, assistant professor in Canadian politics at the University of Toronto.

The Liberals have relied on selective support from the Conservatives to pass economic and trade-related legislation in the last year.

A majority government also allows Carney to decide the timing of the next election. Minority governments are at risk of a snap election if they lose a confidence motion and typically last less than two years.

Carney has solidified his grip on leading Canada until at least 2029, when national elections are due to be held next. The last time a federal government had a majority in parliament was under Justin Trudeau from 2015 to 2019.

Carney’s position strengthened when five opposition legislators in five months defected to the Liberals. Only the governments led by John A Macdonald, Canada’s first prime minister, and Jean Chretien have seen more politicians defect to the ruling party.

On Wednesday, longtime Conservative politician Marilyn Gladu switched parties to join Carney’s government, saying Canada needs “a serious leader who can address the uncertainty that has arrived due to the unjustified American tariffs.“

Of the other two ridings, the Bloc Quebecois is in an extremely tight race with the Liberals in Terrebonne, Quebec. The Liberals won it by just one vote in the last federal election, but the result was overturned by Canada’s supreme court because of a misprint on a voter’s envelope.

The other special election in Ontario is to replace former Liberal lawmaker Bill Blair, who resigned after he was appointed ambassador to the United Kingdom. The Liberals are expected to hold Blair’s seat and were leading early on in counting.

Laura Stephenson, chair of the political science department at the University of Western Ontario, noted that while Trudeau had shifted the party to the left and prioritised issues like reconciliation with Indigenous peoples, rights for minority groups and immigration, there are more pressing matters for Carney, a more centrist leader.

“He is focused on helping Canada survive the economic turmoil, not remaking society,” she said. “When we’re in tough times like this, there are different calculations being made.“

Recent polling from Nanos shows more than half of Canadians prefer Carney as their prime minister, with just 23% picking Conservative leader Pierre Poilievre. Before Carney became leader of the Liberal Party last year, Poilievre had been projected to win the next election by more than 20 points.

“Carney has done a fairly good job showing Canadians he can handle Trump,” said McDougall of the University of Toronto. “He’s shown Canadians he’s a competent manager of the economy and the country,” he said. “And so far Canadians have not been overly impressed by the alternatives.”
