The authorization for the church was given in 1826, and the construction began a year later, finishing in 1853. It served the region’s people by allowing them easy access to religious services instead of travelling an incredibly risky fifty kilometres across the Iroquois river to Montreal.

The magnificent architect Victor Bourgeau was inspired by English neo-classical architecture. The stones with which they built the church came from the quarries of Saint-Blaise. Adding to the entire artistic architecture is a canvas of Saint-Jean-l’Évangéliste above the altarpiece of the high altar painted by Napoléon Bourassa. Numerous stained glass windows offer a beautiful retelling of Christian history.
