Tatiana Auguste


Tatiana Auguste is a Haitian-Canadian politician. She was elected Member of Parliament for Terrebonne in the 2025 federal election, as a member of the Liberal Party of Canada.

Life and career

Auguste was born in Port-au-Prince, Haiti in 2001. Her family immigrated to Canada in 2008, settling in Montreal. She studied economics at Concordia University, afterward working as an E-commerce consultant for the Fédération des chambres de commerce du Québec. Auguste also worked as an assistant to Emmanuel Dubourg, the then-Member of Parliament for Bourassa.
Standing for election for the first time, Auguste was thought to have defeated incumbent Bloc Québécois MP Nathalie Sinclair-Desgagné by 35 votes in the initial vote count. However, subsequent validation of the count by Elections Canada instead showed that Sinclair-Desgagné had retained her seat by a 44-vote margin. Due to the tight margin, an automatic recount was called. On May 10, 2025, the judicial recount in the Superior Court of Quebec flipped the seat back to Auguste by the margin a single vote, the narrowest result in the country. She was one of four people born in the 21st century elected to the House of Commons in the 2025 election. Auguste called the experience "a rollercoaster. From winning to not winning, and then winning again."
On May 13, a Bloc voter disclosed that her mail-in ballot had been returned to her due to a postal code misprint on the envelope provided by Elections Canada. After Elections Canada said that it did not have legal standing to change the result, the Bloc announced on May 15 that it would seek a court order for a new by-election. The same day, Elections Canada stated that five other mail ballots with the incorrect returning address printed had been rejected for having arrived at the Elections Canada office in the riding after the deadline; the statement said that they could not determine if the incorrect address was responsible.
