Terrebonne (federal electoral district)

This article is about the federal electoral district. For the provincial electoral district, see Terrebonne (provincial electoral district). For the pre-Confederation electoral district, see Terrebonne (Province of Canada electoral district).

Terrebonne (French pronunciation: [tɛʁbɔn]) is a federal electoral district in the Canadian province of Quebec. It was represented in the House of Commons of Canada from 1867 to 1997, when it was dissolved in an electoral redistribution. It was reconstituted as an electoral district again beginning with the 2015 election.

History

The riding was originally created by the British North America Act 1867 which preserved existing electoral districts in Lower Canada. It was abolished in 1996 into Repentigny and Terrebonne—Blainville.

It was recreated during the 2012 federal electoral redistribution from parts of Terrebonne—Blainville (51%) and Montcalm (49%), and consisted solely of the city of Terrebonne. After the 2022 Canadian federal electoral redistribution, the southwestern corner of the city was transferred to Thérèse-De Blainville.^[2]

2025 federal election

Main article: Terrebonne in the 2025 Canadian federal election

The riding drew headlines in the 2025 federal election, as it was initially called for the Bloc Québécois, but its recount led to Liberal candidate Tatiana Auguste winning by a margin of one vote, the narrowest result in the country.^[3] One voter in the district had her ballot returned as undeliverable due to an incorrect postal code printed on the pre-addressed ballot return envelope from Elections Canada; had her vote for the Bloc Québécois candidate been counted, the result would have been tied.^[4] After Elections Canada stated that it did not have legal standing to overturn the judicial recount, the Bloc Québécois announced that it would be asking the Superior Court of Quebec for a new by-election to be held.^[5]
