Liberals win Terrebonne rematch after previous one-vote victory overturned
TERREBONNE — Liberal candidate Tatiana Auguste won the Terrebonne riding north of Montreal for the second time in a year Monday after her one-vote victory in 2025 was overturned by the courts.
With all ballots counted, she led with 48.4 per cent of the vote compared to 46.8 for Bloc Québécois candidate Nathalie Sinclair-Desgagné, securing a clean sweep in the evening’s three byelections for Prime Minister Mark Carney.
Elections Canada had declared Auguste the winner over Sinclair-Desgagné by a single vote following the April 28 federal election last year.
Sinclair-Desgagné challenged the results after a supporter complained that she had tried to vote by mail using a special ballot that was never counted.
