Therese-De Blainville is a suburban riding in the lower Laurentians, immediately north of Laval on the north shore of the Riviere des Mille-Iles. The riding encompasses the cities of Blainville, Sainte-Therese, Boisbriand, and Rosemere, with a combined population of approximately 164,000 as of the 2021 census. The district has a predominantly francophone character, though a growing immigrant population has added diversity in recent years.

About the Riding

Therese-De Blainville is a prosperous suburban corridor that has experienced steady population growth as families seek more space and lower housing costs while maintaining access to Montreal's employment market. Sainte-Therese has a vibrant commercial core and is home to the Cegep Lionel-Groulx, one of the region's major post-secondary institutions. Blainville, the riding's largest city, has grown into a significant employment centre in its own right, with a mix of retail, professional services, and light industry. Boisbriand hosts a cluster of pharmaceutical and high-tech employers, while Rosemere is known for its wooded residential streets and access to the Riviere des Mille-Iles.

In 2025, the riding's federal debates centred on housing affordability in a suburban market where prices have risen sharply over the past five years, the cost of living for middle-class families, and healthcare access. The threat of US tariffs on Quebec's manufacturing and pharmaceutical exports was a tangible concern for workers in Boisbriand's industrial parks. Immigration levels and the adequacy of integration services also featured in the campaign, as the riding's demographics have shifted with newcomer settlement expanding beyond the Island of Montreal into the lower Laurentians.
