He did his theological training at the Grand Séminaire de Montréal and was ordained a priest by Édouard-Charles Fabre in 1888.[1] In 1913 he was appointed the Bishop of Joliette, and in 1928, he was appointed the Archbishop of Ottawa. He was the Archbishop of Ottawa and the Chancellor of the University of Ottawa until his death on May 22, 1940.[2]
