Sacred Music

St. Michael’s Choir School strives to serve God, the Universal Church, the Archdiocese of Toronto, and the community with commitment and joy through sacred music. It also works to safeguard and develop the living tradition of music specific to the Roman Rite, with a focus on Gregorian chant and polyphony.

The Choir School is a resource for knowledge in sacred music and liturgy. If you are a researcher, scholar or composer looking for information or resources specific to sacred music, please contact us at
