Saint-Grégoire, Administrative sector in Bécancour, Canada.

Saint-Grégoire is the westernmost sector of Bécancour, Quebec, crossed by Autoroutes 55 and 30 and Route 132. Its centre is the church of Saint-Grégoire-le-Grand, built from 1803 to 1806, a gathering place for weddings and funerals that many residents consider the heart of the community.

Acadians deported from Beaubassin in 1755 settled in the Bécancour area from 1758 and founded the village of Sainte-Marguerite, today Saint-Grégoire. The parish was canonically erected in 1802 and the church built from 1803 to 1806. The municipality of Saint-Grégoire-le-Grand was created in 1855; the village of Larochelle split off in 1863, and both merged into Bécancour in 1965.

The Roman Catholic church of Saint-Grégoire serves the French-speaking population through religious ceremonies, masses, and community gatherings throughout the year.

The sector connects to major transportation routes including Autoroute 55, Autoroute 30, and Route 132, providing convenient access for residents and visitors. The good road connections make it straightforward to reach from different directions in the region.

The church of Saint-Grégoire-le-Grand was recognized as a heritage building in 1957 and is considered by many residents to be the heart of the community. It hosts weddings and funerals, and the hockey player Zachary Bolduc, who went on to the Montreal Canadiens, comes from the sector.
