Therese-De Blainville

A newly created riding born from the 2012 redistribution, Therese-De Blainville sits in the densely populated suburban belt north of Montreal. The district draws together the municipalities of Blainville, Sainte-Therese, Bois-des-Filion, and Lorraine -- communities that had previously been split between the old ridings of Terrebonne--Blainville and Marc-Aurele-Fortin. The riding is among the most densely populated in Quebec outside the island of Montreal.

Candidates

Ramez Ayoub (Liberal) -- Born in Syria, Ayoub studied economics at the Universite de Montreal and built a career as a real estate broker before entering municipal politics. He served on Lorraine's city council for a decade, then was elected mayor of Lorraine in 2009, a position he held heading into the federal campaign. He also served as deputy prefect of the Therese-De Blainville regional county municipality.

Alain Marginean (Bloc Quebecois) -- A veteran of more than thirty years at College Lionel-Groulx, where he had served as director of continuing education, Marginean was also working as interim coordinator of ABL-Immigration at the time of the campaign. He had previously run provincially for Option Nationale in the 2012 and 2014 Quebec elections and placed Quebec independence at the centre of his federal campaign.

Alain Giguere (NDP) -- A tax lawyer by profession who held a bachelor's degree in political science, a bachelor's degree in legal science, and a certificate in social justice, Giguere had run unsuccessfully in seven federal elections between 1984 and 2008 before finally winning the neighbouring riding of Marc-Aurele-Fortin in the 2011 NDP wave. He ran in the new Therese-De Blainville district after redistribution redrew his constituency's boundaries.

Manuel Puga (Conservative) -- Puga stood as the Conservative candidate in a riding where the party drew its support primarily from the more affluent suburban pockets.

Andrew Carkner (Green Party) and Daniel Guindon (Libertarian) also ran.

About the Riding

The municipalities that compose Therese-De Blainville are classic north-shore commuter suburbs, with residents travelling into Montreal via Autoroute 15 or the Exo commuter rail network. Sainte-Therese, the oldest settlement, hosts College Lionel-Groulx and serves as a commercial centre, while Blainville has experienced rapid residential growth. Lorraine is among Quebec's wealthiest municipalities, and Bois-des-Filion sits along the Riviere des Mille Iles. As a brand-new riding, there was no incumbent, making this an open contest. Transportation infrastructure -- particularly highway congestion and commuter rail service -- was a persistent concern for residents who depended on efficient links to Montreal. The three-way race between the Liberals, the Bloc, and the NDP reflected the broader uncertainty about Quebec's political loyalties in the 2015 campaign.
