Montcalm

Montcalm is a federal electoral district in the Lanaudière region north of Montreal, a sprawling riding that mixes rapidly expanding suburbs with quieter rural communities in the foothills of the Laurentians. Bloc Québécois veteran Luc Thériault has represented the riding since 2015 and entered the 2025 campaign seeking a fourth consecutive mandate.

About the Riding

Montcalm encompasses the Montcalm Regional County Municipality, the city of Mascouche, and the districts of La Plaine and Lachenaie in the city of Terrebonne. The southern portion of the riding, particularly Mascouche and Terrebonne, has experienced explosive suburban growth as young families priced out of Montreal have moved northward along the Highway 25 corridor. The northern areas, including municipalities like Sainte-Julienne and Saint-Lin--Laurentides, retain a more rural and agricultural character.

The Lanaudière region sits between the Saint Lawrence River lowlands and the Laurentian highlands, and the riding reflects that geographic transition. The flat farmland in the south gives way to rolling hills and forests as one moves north toward the Laurentians. This mix of suburban and rural communities creates a diverse electorate with concerns ranging from commuter transit and housing development to agricultural policy and rural broadband access.

Thériault's consistent re-elections in Montcalm reflect the Bloc's enduring appeal in francophone communities north of Montreal, where concerns about Quebec's autonomy, language protection, and cultural identity remain potent political forces. The 2025 campaign tested whether the Liberal resurgence under Mark Carney could penetrate this Bloc heartland, but Thériault's deep roots in the riding and his reputation as a hardworking constituency MP proved decisive once again.
