St. Michael's Choir School is a unique institution in Toronto, a Catholic' boys school combining a regular academic curriculum with intense focus on choral practice.

The school is marking its 75th anniversary this year and boasts some of Canada’s best male singers among its graduates, people like Kevin Hearn of the Barenaked Ladies and CBC radio host Andrew Craig.
