The 2025 results are left out because elections.ca’s terms forbid commercial reproduction; the open catalogue’s latest is 2021. Provincially the last general election was on 5 October 2026, for the National Assembly of Québec; federally, on 28 April 2025. Trois-Rivières votes next on 4 November 2029: the Act respecting elections and referendums in municipalities sets municipal elections on the first Sunday in November every four years.
