Rosemont—La Petite-Patrie

Rosemont—La Petite-Patrie is an urban riding in the heart of Montreal, covering the borough of the same name on the central-east portion of the island. With a population of roughly 141,800, it is one of the most densely populated ridings in Quebec and the third most populous borough in Montreal. Originally a working-class district, the neighbourhood has gentrified considerably since the early 2000s, attracting younger professionals, artists, and families while retaining significant Italian, Vietnamese, and Latin American communities. More than half of the borough's families have children living at home, and the proportion of single-person households—particularly among seniors—is notably higher than the Montreal average.

About the Riding

The riding is centred on two distinct but interconnected neighbourhoods. Rosemont is a residential area with tree-lined streets, community parks, and a strong neighbourhood identity, while La Petite-Patrie—once defined by its proximity to the Jean-Talon Market and the Italian community along Saint-Hubert Street—has become a hub for young professionals and creative industries. The borough hosts a lively commercial scene along Beaubien, Masson, and Saint-Hubert streets.

In 2025, the riding's federal campaign was shaped by housing affordability in a rapidly gentrifying neighbourhood where rental prices have climbed sharply, the cost of living for middle-class and working-class residents, and the adequacy of federal investments in public transit and urban infrastructure. As the last NDP-held seat in Quebec—and one of the few NDP seats east of Winnipeg—Rosemont—La Petite-Patrie carried outsized symbolic importance for the party's national relevance in the province.
