Trois-Rivieres

Trois-Rivieres sits at the mouth of the Saint-Maurice River on the north shore of the St. Lawrence, midway between Montreal and Quebec City. One of the oldest cities in North America, founded in 1634, it serves as the regional capital of Quebec's Mauricie region. With a population of roughly 139,000 as of the 2021 census, Trois-Rivieres is a mid-sized city that has reinvented itself from its pulp-and-paper origins into a more diversified economy. Over 93 percent of residents speak French as their mother tongue.

About the Riding

Trois-Rivieres has undergone a significant economic transition over the past two decades. The city's historic pulp-and-paper mills have largely closed, replaced by a more diversified base that includes metal transformation, electronics, thermoplastics, and cabinet making. The Universite du Quebec a Trois-Rivieres and the Cegep de Trois-Rivieres are major institutional employers and research hubs, particularly in hydrogen energy, which has become a signature local initiative. The city's port on the St. Lawrence handles cargo and cruise ships, while the cultural sector -- anchored by institutions like the Amphitheatre Cogeco -- contributes to a growing tourism economy.

In 2025, the riding saw a rare three-way competitive race among the Liberals, Bloc, and Conservatives. High-speed rail connecting Trois-Rivieres to Montreal and Quebec City was a signature local issue, as the city's geographic midpoint position made it a natural beneficiary of such a project. Cost of living, healthcare access, and the impact of US tariffs on the region's manufacturing exports were also central campaign themes. The Liberal breakthrough ended four decades of non-Liberal representation and was seen as one of the most significant seat changes in Quebec during the election.
