The Toronto Mendelssohn Choir is a Canadian large vocal ensemble based in Toronto. It was co-founded in 1894 by Augustus S. Vogt and W. H. Hewlett to celebrate the opening of the Massey Hall. The ensemble was originally an extension of the choir of Jarvis St. Baptist Church in Toronto which Vogt directed and Hewlett accompanied. It is named after the German composer, Felix Mendelssohn.
