Danielle Martin Secures Majority for PM Mark Carney in University-Rosedale

Prime Minister Mark Carney’s Liberal government secured a majority in the Canadian House of Commons following a sweep of three federal byelections on April 13, 2026. The wins in Ontario and Quebec brought the Liberal seat count to 174, surpassing the 172-seat threshold required for a majority government.

The Liberal party had been one seat shy of a majority prior to the byelections, a position reached after five opposition politicians joined the ruling party in the months leading up to the votes. The victory in the three contested ridings provided the government with a more stable legislative foundation to advance its policy agenda.

Byelection Results and Seat Distribution

The Liberals won all three available seats. In Toronto, Danielle Martin won the riding of University—Rosedale, while Doly Begum secured the seat in Scarborough Southwest. In Quebec, Tatiana Auguste won the riding of Terrebonne.

The race in Terrebonne was the most contested of the three. According to Elections Canada, Tatiana Auguste defeated Nathalie Sinclair-Desgagné of the Bloc Québécois by 731 votes after 100 per cent of the polls reported.

The win in University—Rosedale was the first to be called on April 13, 2026, and served as the mathematical trigger for the majority government. While the win in that riding alone reached the 172-seat requirement, the additional victories in Scarborough Southwest and Terrebonne increased the total to 174 seats.

Profile of Danielle Martin

Danielle Martin, the new Member of Parliament for University—Rosedale, is a family physician with an extensive background in healthcare administration and academia. She previously served as the executive vice-president of Women’s College Hospital and led the department of family and community medicine at the University of Toronto.

Martin has prior experience in international policy discussions regarding healthcare. In 2014, she appeared before a United States Senate subcommittee to provide testimony on Canada’s public health care system.

In the University—Rosedale byelection, Martin defeated three opponents: Conservative candidate Don Hodgson, New Democrat Serena Purdy, and Green Party candidate Andrew Massey.

Vacancy in University—Rosedale

The University—Rosedale seat became vacant in January 2026 following the resignation of former Liberal MP and deputy prime minister Chrystia Freeland. Freeland resigned to take on two roles: serving as an economic adviser to Ukrainian President Volodymyr Zelenskyy and becoming the CEO of the Rhodes Trust at Oxford University.

Government Mandate and Priorities

Following her victory, Danielle Martin stated that the results provided the Liberal team with a more powerful mandate to continue their work. During a speech to supporters at El Mocambo in central Toronto on April 13, 2026, Martin emphasized that the majority was a directive for immediate action.

Now, this is not a mandate to be quiet. It is not a mandate to take our time. It is a mandate to get to work on housing, on affordability, on healthcare, and climate change, and infrastructure, on the future of our economy and the public services that are more important to this country than ever.

Martin noted that her professional experience as a physician—specifically the skills of listening and building relationships—would be central to her approach in Ottawa and within her community. She described her career as being focused on building the services and institutions that support people during the most difficult moments of their lives.
