By Decree of Erection the Parish of St. Thomas More, Scarborough, was established by the Archdiocese of Toronto on June 15, 1964 and divided from the parish of St. Rose of Lima. The Decree was signed by Coadjutor Archbishop of Toronto, Philip F. Pocock. The official Decree was sent to Reverend E. J. Platt, as the first pastor of Saint Thomas More Parish, on June 25, 1964. The solemn blessing of the Church of Saint Thomas More took place on Sunday, September 10, 1967 with his Grace The Most Rev. Philip F. Pocock officiating.
Over the next 50 years since the establishment of the Parish there were many highlights and memories that enrich the story of our parish and we share a few of these memories in the following pages. We trust that they will trigger many happy reminiscences for our parishioners.
