Crosbie Brough was Archdeacon of Huron and Isaac Hellmuth of London.^[2] In addition to London, other major communities within the diocese are: Brantford, Cambridge, Chatham, Kitchener, Sarnia, Stratford, Waterloo, and Windsor. The diocese maintains chaplaincies at Canterbury College in Windsor, Renison University College in Waterloo and Huron University College in London, which has an affiliated seminary.
