The Elora Festival Singers (EFS), a professional chamber choir, was founded in 1980 by Noel Edison as the principal choral ensemble of the Elora Festival. In 1992, the Elora Festival Singers was incorporated as a separate organization to manage its year-round activities. Since 1997, the choir has been the professional core of the Toronto Mendelssohn Choir and the Mendelssohn Singers, and is the choral ensemble-in-residence of the Elora Festival for four weeks each summer.
