Trois-Rivières

Trois-Rivières was an urban riding centred on one of Quebec's oldest and most historically significant cities, located at the confluence of the Saint-Maurice and St. Lawrence rivers, approximately halfway between Montreal and Quebec City. The riding encompassed most of the city of Trois-Rivières, excluding the former municipalities of Trois-Rivières-Ouest and Pointe-du-Lac. With a census metropolitan area population of roughly 152,000 as of 2011, Trois-Rivières served as the economic and administrative capital of the Mauricie region.

About the Riding

Founded in 1634, Trois-Rivières was the second-oldest city in Canada and had long served as a gateway to the vast Mauricie hinterland. The city's economy had historically been anchored by the pulp and paper industry—by 1930, Trois-Rivières was considered the world capital of paper production, with four large mills operating at the estuary of the Saint-Maurice River. While the paper sector had contracted significantly by 2011, the Kruger mill continued to operate as a major employer, and the city's industrial base had diversified into metal transformation, electronics, thermoplastics, and cabinet making. An industrial park adjoining the Trois-Rivières airport also served the aeronautical sector.

The founding of the Université du Québec à Trois-Rivières in 1969 had been transformative for the local economy, helping to build a significant tertiary sector in education, health care, and professional services. The university's research strengths in pulp and paper science, hydrogen energy, and biomaterials reflected the region's industrial heritage while pointing toward new economic directions. The Centre hospitalier régional de Trois-Rivières served as the region's major health-care facility.

Trois-Rivières was overwhelmingly francophone, with over 96 percent of residents reporting French as their mother tongue. The city's median age was notably older than the provincial average, reflecting the outmigration of younger residents and a mature population base. The riding had been held by the Bloc Québécois since 2004. Federal issues of concern included support for the struggling pulp and paper sector, economic diversification, infrastructure for the aging city centre, and research funding for the university.
