Terrebonne

The federal riding of Terrebonne consists entirely of the city of the same name — a large off-island suburb of Montreal located in the Lanaudiere region, on the north shore of the Riviere des Mille-Iles directly across from Laval. The city is divided into three sectors — the old seigneurial town of Terrebonne, Lachenaie to the east, and La Plaine to the north — that were merged into a single municipality in 2001. With a population approaching 120,000 in the 2021 census, Terrebonne is Montreal's third-largest suburb and the largest city on the North Shore. The population is overwhelmingly francophone and has grown rapidly since the 1980s, driven by families seeking affordable housing within commuting distance of Montreal.

About the Riding

Terrebonne's heritage dates to the early eighteenth century, when the seigneurial mill complex on the Ile-des-Moulins — now a classified historic site — anchored the local economy. The island's restored flour mill, sawmill, and bakery recall the era when Terrebonne was a hub of the fur trade and timber industry. The old town, known as Vieux-Terrebonne, remains a popular cultural destination with its narrow streets, heritage buildings, and summer theatre festivals.

Modern Terrebonne, however, is defined by rapid suburban expansion. The Lachenaie and La Plaine sectors are dominated by single-family housing developments, big-box retail, and highway infrastructure connecting residents to Montreal via Autoroute 25 and Autoroute 640. The city's explosive growth — from under 25,000 residents in 1986 to nearly 120,000 by 2021 — has strained municipal services and fuelled demand for better public transit links.

The riding was reconstituted during the 2012 federal redistribution from portions of the former Terrebonne—Blainville and Montcalm ridings. In 2021, the Bloc Quebecois won the seat convincingly, reflecting the party's strength in the francophone suburban belt north of Montreal. Local issues centred on transportation, the environment — including the future of a former military firing range — and the cost of living for young families.
