Welcome to St. Mary’s Parish!

Our parish was founded in 1964 to serve the English speaking population of the Roman Catholic Diocese of St. Jean-Longueuil. Located in the center of Greenfield Park, Catholics from surrounding municipalities have made St. Mary’s their spiritual home.

Our parishioners are local residents, refugees from oppression, and immigrants from the four corners of the world. Many languages are spoken by our parishioners but there is one unifying language, the word of our Lord.

We invite you to visit our Catholic community, participate in our event and celebrate mass with us.
