In a night that went down as a turning point in Canadian political history, Prime Minister Mark Carney and his Liberal Party achieved what many analysts had thought impossible just a year prior. By sweeping all three federal by-elections held on April 13, 2026, the Liberals not only dismantled a decades-old sovereignist stronghold in Quebec but also officially secured a majority government in the House of Commons.
Newly-elected liberal candidate, Tatiana Auguste.
The centerpiece of this victory took place in the riding of Terrebonne, where the “operation seduction” led by the Prime Minister and his candidate, Tatiana Auguste, finally bore fruit. Despite a relentless counter-offensive by the Bloc Québécois, the Liberals emerged victorious in Terrebonne for the second time in a year—definitively signaling the fall of a sovereignist “château fort.”
The Battle for Terrebonne: A Midnight Verdict
The race in Terrebonne was a grueling, high-stakes rematch. In 2025, Tatiana Auguste had won the seat by a hair-thin margin of just one vote, only to have the result annulled by the Supreme Court of Canada in February 2026 due to mail-in ballot irregularities. When the new vote was called, the mandate became clear.
By a margin of 731 votes, Auguste (48.4%) defeated the Bloc’s Nathalie Sinclair-Desgagné (46.8%). The final result was not confirmed until 12:15 a.m., following a tense night where the lead swapped hands dozens of times as individual boxes were counted.
The atmosphere at the Liberal campaign headquarters was electric. As the final polls came in, a crowd of volunteers, MPs, and high-ranking ministers erupted in cheers. With this win, the Liberals secured a riding that, prior to Auguste’s efforts, had not been Liberal since 1984. For most of the three decades between 1993 and 2025, Terrebonne had been considered safe territory for the Bloc Québécois—until that night.
“I am ready; we are getting to work,” a triumphant Auguste told her supporters during her victory speech. “I will work every day to ensure that the voice of Terrebonne is heard loud and clear in Ottawa.”
A Triple Crown for Mark Carney
While the eyes of the nation were fixed on the drama in Quebec, the Liberal machine proved equally dominant in Ontario. The party successfully defended two key ridings in Toronto, completing a “triple crown” that pushed their seat count to 172—the magic number required for a majority government.
University–Rosedale: In the seat formerly held by Chrystia Freeland, Liberal candidate Danielle Martin, a well-known physician and health-care executive, secured a massive victory with over 63% of the vote. Martin’s win was projected early in the evening, underscoring the deep-rooted Liberal support in the heart of Toronto.
Scarborough–Southwest: This riding saw the successful political transformation of Doly Begum, the former provincial NDP deputy leader who had crossed floors to run for the federal Liberals. Begum won handily, further cementing the Liberal grip on the Greater Toronto Area and dealing a personal blow to the NDP’s new leadership.
The Shift in the Political Landscape
These by-elections were widely viewed as a “Test of Year 1” for Mark Carney’s leadership. Since taking the helm, Carney had positioned himself as a steady hand for “middle powers” in a volatile global economy. The results suggested that his brand of pragmatism resonated with voters who might have otherwise drifted toward the opposition.
Conversely, the night was a “cold shower” for the other federal leaders. Pierre Poilievre’s Conservatives suffered a staggering loss of support in Terrebonne, where their candidate, Adrienne Charles, plummeted to just 3.3% of the vote—a massive 15-point drop from previous showings. Poilievre, who did not visit the riding during the campaign, faced immediate questions about his party’s relevance in suburban Quebec.
For the NDP, the night was equally grim. Under the brand-new leadership of Avi Lewis, who had been elected just weeks prior, the party barely registered on the scoreboard. Their candidate in Terrebonne, Maxime Beaudoin, finished with a meager 0.5%. The loss of Doly Begum to the Liberals in Scarborough added insult to injury, suggesting that the “Carney Liberals” had successfully poached both the NDP’s talent and its base.
Final Results Summary
Riding: Winning Candidate Party: Key Significance:
Terrebonne Tatiana Auguste Liberal Ended 30 years of Bloc dominance.
University–Rosedale Danielle Martin Liberal Maintained core urban Toronto support.
Scarborough–S.W. Doly Begum Liberal Cemented majority through floor-crossing.
The victory gave the Carney government a clear runway to implement its legislative agenda without the need for opposition support. From the proposed TGV Alto high-speed rail project—which the Bloc had fought bitterly—to new national economic measures, the Prime Minister finally held all the cards. As the dust settled, the Liberal Party celebrated a night of historic gains that redrew the Canadian political map.
Auguste Signals New Era to Voters
Auguste’s message to the media post-victory in Terrebonne was not triumph so much as access. The newly-elected liberal candidate said she considers the result as a chance for Terrebonne to finally have a stronger voice where decisions are made.
She thanked voters for their trust and said she was ready to work with them, repeatedly returning to one idea: that Terrebonne now has a place “at the decision table.”
After a year of recounts, court fights and political suspense, Auguste tried to present the result less as a personal comeback than as a mandate to deliver results for the riding. She said the campaign had been about getting projects done in Terrebonne and believed voters backed her because, after nine months in the public eye, they fully knew who she was and what she stood for.
“I just wanted to thank the citizens of Terrebonne for the confidence that they put in me,” she said to the media. “I am ready to work with them.”
Auguste also did not pretend the race was comfortable. As results trickled in through a tight count, she acknowledged she had expected a fight and said her team gave it everything it had. Her caution matched the mood of the evening, with the Liberal candidate holding a lead that remained narrow before winning out against her Bloc Québécois counterpart.
The result returned a Liberal to Terrebonne in a by-election which came about by unusual political baggage. In her first reaction, Auguste’s message was clear: now that voters know her, she says Terrebonne can expect her to get to work.
