Ville-Marie—Le Sud-Ouest—Île-des-Soeurs

This Montreal riding weaves together three contrasting urban environments: the downtown core of Ville-Marie with its office towers, university campuses, and Old Montreal; the historically working-class neighbourhoods of Le Sud-Ouest lining the Lachine Canal; and the quieter residential island community of Île-des-Soeurs (Nuns' Island) in the St. Lawrence River.

Candidates

Marc Miller (Liberal) — A corporate lawyer who practised mergers and acquisitions at Stikeman Elliott in Montreal, Stockholm, and New York before entering politics. Miller held both common and civil law degrees from McGill University, as well as bachelor's and master's degrees in political science from the Université de Montréal. A former soldier in the Canadian Armed Forces, he was first elected in 2015 and made history in 2017 by delivering a statement in the House of Commons entirely in the Mohawk language.

Sophie Thiébaut (NDP) — A municipal councillor in the Saint-Henri–Est—Petite-Bourgogne—Pointe-Saint-Charles—Griffintown district since 2009. Thiébaut founded Mobilisation Turcot in 2007, a citizens' movement that pushed for sustainable redevelopment of the Turcot Interchange with improved public transit connections for the Sud-Ouest.

Nadia Bourque (Bloc Québécois) — An orthopedagogue working in a school setting who made the environment and affordable housing the centrepieces of her campaign. She called for better access to federal funds for community organizations in the riding and measures to combat homelessness.

Michael Forian (Conservative) — A political operative with extensive experience in both federal and provincial campaigns who worked the riding for months ahead of the election. Forian participated actively in riding-level debates on reconciliation and environmental policy.

Liana Canton Cusmano (Green Party) — A writer, spoken-word artist, and filmmaker who highlighted local pollution concerns during the campaign, including sewage discharge into the St. Lawrence and air quality issues near Highway 720.

Jean Langlais (People's Party), Tommy Gaudet (Parti Rhinoceros Party), Louise B. O'Sullivan (Independent), Marc Patenaude (No Affiliation), and Linda Sullivan (ML) also appeared on the ballot.

About the Riding

Few federal constituencies in Canada contained as sharp a contrast between affluence and precarity. The Ville-Marie borough encompassed the financial district, the Quartier des spectacles, and the campuses of both Concordia and McGill universities, while just across the Lachine Canal, neighbourhoods like Pointe-Saint-Charles and Little Burgundy had long been among Montreal's lowest-income communities. Griffintown, largely derelict for decades following deindustrialization, had undergone an intense condo building boom since the early 2000s that was rapidly reshaping the area's social fabric. Rising rents in Saint-Henri and surrounding streets were displacing long-standing tenants, making gentrification and affordable housing among the most heated campaign issues. French was the most common home language at roughly 43 percent, but English, Arabic, Mandarin, and Spanish were also widely spoken in a riding where approximately one-third of residents were born outside Canada. The riding's large student population added a transient but politically engaged demographic layer to every contest.
