St Maurice was one of a wave of parishes founded in the 1960s as the population of the western suburbs soared. Located in the area known as Cityview, the new parish was in fact created in tandem with St. Monica's in the Merivale area, though the administration of the two new churches was to be kept completely separate as noted in Archbishop Lemieux's decree of February 7, 1964.

The name of St. Maurice was chosen in honour of Archbishop Lemieux's patron saint. The first pastor was Father Orloff Dorion. Mass was at first said in schools until a church could be built on Meadowlands Drive.

Construction began in December 1964 and was completed in time for the first mass

on September 5, 1965. The church was blessed by Archbishop Lemieux the following February 5.

A brown brick structure, the church has a feeling of spaciousness and provides good sight lines with its theatre-like sloping floor. The parish has continued to grow as more new development has occurred in the area and now serves a population of approximately 6,500 (1992 statistics).

In the thirtieth anniversary year of 1994, the parish also celebrated paying off its mortgage. This now permitted the permanent consecration of the church, a ceremony carried out on September 18 by Archbishop Marcel Gervais. A reception and parish picnic completed this memorable day in the life of the parish.
