The Palestrina Choir , established in 1946, ensured the continued existence of choral singing on campus. This mixed-voice group of about eighty people performed secular as well as sacred music. Its work was continued by the Collegium Musicum , founded in 1965. Under Mr. Bernier's leadership, the Choir took on works of increasing scope. Over the past twenty-five years, the Choir has performed many major classical works dating from the Renaissance to the twentieth century.
Canadian works are also an important part of the ensemble's repertoire.
It also has performed with professional orchestras, including Thirteen Strings , the Hungarian State Symphony Orchestra and the Ottawa Symphony Orchestra . In June 1993, the Choir completed a very successful tour in the south of France, under the direction of Laurence Ewashko. In July 1996, again under Laurence Ewashko's direction, the Choir won the first place in the mixed choir category at the International Choral Kathaumixw held in Powell River, British Columbia.
