The Liberal Party of Canada candidate Tatiana Auguste won the Terrebonne byelection Monday after the Liberals won all three races and secured a majority in parliament.
Auguste won the election with a 731-vote margin over Bloc Québécois candidate Nathalie Sinclair-Desgagné in what was a rematch of the April 2025 election.
Residents of Terrebonne returned to the polls on Monday for a byelection that was called after the Supreme Court of Canada overturned the results of the previous vote. In that general election, Liberal candidate Auguste won by a single vote against the incumbent Bloc Québécois MP Sinclair-Desgagné.
The race remained close throughout the evening as the vote count began soon after polls closed at 8:30 p.m.
In the opening round, with five of 211 polling stations counted, cheers erupted from Bloc Quebecois side as Sinclair-Desgagné held a one-vote lead, with a preliminary result of 138 votes to 137 for Liberal candidate. Both the candidates overtook the other multiple times as results rolled in.
However, by 12:15 a.m. Tuesday with all the 211 polls reported, Auguste had won 48.4 per cent compared to Sinclair-Desgagné had received 46.8 per cent.
Earlier in the day, voters in Terrebonne told CityNews why they showed up to vote.
“I think I’m voting for a change in Terrebonne. Very interesting time right now,” said one Terrebonne resident.
“The race was tight the last time around, so it’s even more important to go out and vote,” said Terrebonne voter Sylvain Hebert. “My vote did change with the whole judicial procedure; my choice is different this time.”
“It’s the campaigning by the candidates that made me change my mind – their presence and actions in the last weeks,” Hebert added.
While Hebert changed his vote, other voters said their choice won’t change in the rematch.
“I’m pretty great with the choice I made last time,” said Maude Bourdage.
Camuel Desir Cote said, “My vote hasn’t changed, it’s the same.”
“Very interesting time right now – it’s a cultural and demographic shift that I would like to be a part of – sometimes change is interesting, and sometimes you have to change even when the leaders are great, you have to change them from time to time to make sure you have fresh and noble ones,” said Ghyslain Cote.
Diane Laurain Dinenna said, “Whether it’s Terrebonne or elsewhere, it’s important to go vote.”
More than 18,000 people – one-fifth of Terrebonne voters – have cast their ballots in advance polling.
