Admitted to the Law Society of Upper Canada in 1993, Silvester holds a Bachelor of Arts in North American history from McGill University (1987) and a law degree from the University of Toronto (1990), and articled with the Constitutional Law and Policy branch of Ontario's Ministry of the Attorney General.
