The Church of St. Peter the Apostle is a Canadian Roman Catholic parish church. Construction of a church for the community and the local people was begun in 1850. The architect was Victor Bourgeau, who was a noted ecclesiastical architect in the city, building the Basilica of Notre-Dame and St. James Cathedral in Montreal, as well as Saint-Joachim de Pointe-Claire Church in Pointe-Claire, Quebec.
The complex to which the church belongs consists also of the rectory and sacristy, as well as a clock tower and the former choir school and elementary school. The church has three naves, which terminate under a polygonal apse. The rectory, built 1854-1856, is of the same height as the church, built in the neoclassical style. The choir school was established in a small wooden house on the property of the Oblate community in 1859 as a private school for boys, which was replaced by the current structure in 1868. The church also boasts of an organ made by Casavant Frères in 1908. The stained glass windows, crafted 1853-1883, were created by the House of Champigneulle, in Bar-le-Duc, France.
Today the church holds the Chapel of Hope, dedicated to the victims of AIDS, perhaps the only one of its kind in the world.
