Silvester studied organ with C. Spencer Heap in England and, after moving in 1921 to Canada, with Lynnwood Farnam in Saskatoon.

He moved to Toronto in 1929, studied at the TCM with MacMillan (organ) and Willan (theory and composition), and was organist 1931-1938 at the Church of the Messiah and 1938-1966 at Bloor Street United Church, where he led the choir in many large works.

He gave organ recitals in many parts of Canada and on the CBC and was president 1945-1947 of the CCO.

Of his work with the choir, George Kidd wrote, 'The overall effect is one of good discipline, a clear understanding, and a sincerity that spreads itself over all sections'.

[2] Silvester is credited with being the organ teacher of Glenn Gould.
