Prime Minister Mark Carney's Liberal government secured a parliamentary majority late Monday after victories in two Toronto federal by-elections. The wins in University, Rosedale, and Scarborough Southwest brought the party's seat total to 173 in the 343-seat House of Commons.

CBC News projected Liberal candidate Danielle Martin, a family physician, as the winner in University-Rosedale. With 80 per cent of polls reporting, Martin held about 65 per cent of the vote, or roughly 15,521 ballots, ahead of the New Democrats at 18 per cent and Conservatives at 13 per cent. The riding became vacant after former Liberal MP Chrystia Freeland resigned in January to advise Ukraine's president.

In Scarborough Southwest, Doly Begum claimed 69.9 per cent of the vote with 19,936 ballots out of 28,522 valid votes cast. Conservative Diana Filipova received 18.4 per cent, or 5,249 votes, while the NDP garnered 6 per cent. The seat opened following the resignation of Liberal MP Bill Blair, now Canada's High Commissioner to the United Kingdom.

The results in the two Toronto ridings proved decisive. Carney's Liberals entered the by-elections one seat short of a majority, bolstered by recent floor-crossings from opposition MPs, including former Conservative Marilyn Gladu and the NDP's Lori Idlout. Holding these traditionally safe Liberal seats pushed the party over the threshold.

A third by-election in Terrebonne, Quebec, remained too close to call late Monday, with Liberal incumbent Tatiana Auguste leading Bloc Québécois candidate Nathalie Sinclair-Desgagné 48.6 per cent to 46.7 per cent at 57 per cent reporting. The riding's 2025 general election result had been annulled by the Supreme Court due to an Elections Canada error on mail-in ballots.

Carney assumed the Liberal leadership in March 2025 and became prime minister shortly after, succeeding Justin Trudeau. His party formed a minority government following the April 2025 federal election amid tensions with the U.S. over trade. The minority status required negotiation with other parties to pass legislation.

The new majority frees the government from such dependencies, strengthening its hand on issues like economic policy and U.S. relations. Conservative Leader Pierre Poilievre had hoped for upsets to deny Carney the milestone. Turnout figures were not immediately available for the by-elections.
