In the 1950s, the Archbishop of St. John's, Patrick Skinner decided that the area needed a chapel and school of its own.

The ground floor of the school became a chapel and was also dedicated to Saint Pius X on 15 January 1956.

[3] The St Pius X chapel remained a mission of the basilica until 1962, when Archbishop Skinner invited the Society of Jesus to take over the administration of the parish and set up Gonzaga High School.

The Jesuits, that year, reopened an independent Catholic school, Saint Bonaventure's College in the city.

[3] St. Pius X Church closed in 2022 after being sold as part of the archdiocese liquidating its holdings in an effort to raise money to compensate victims of abuse.
