St. Michael’s Choir School was founded in 1937 by Monsignor John Edward Ronan to facilitate the training of a boys’ choir for St. Michael’s Cathedral. A vital part of the Toronto Catholic community, the school was honoured by the Vatican on May 17, 1955.

In 2013, St. Michael’s Choir School celebrated its 75th Anniversary with a performance tour of Rome and Florence. St. Michael’s Choir School has toured internationally since 1967, Canada’s centennial year. This once-in-a-lifetime opportunity saw the students of St. Michael’s Choir School perform at some of the world’s most important sacred music venues, including a prestigious performance at the Solemn Mass at St. Peter’s Basilica with His Eminence Thomas Cardinal Collins, Archbishop of Toronto.
