At the invitation of Bishop Michael Power of Toronto, five Loreto Sisters under Mother Teresa Ellen Dease arrived in the city in 1847 and founded their first school. Since the 1920s their motherhouse has been at Loretto Abbey (Hoggs Hollow), which housed a girls' secondary school: Loretto Abbey Catholic Secondary School. In 1987 management of the school was turned over to the Toronto Catholic District School Board. The Sisters also founded Loretto College School on Brunswick Avenue in 1915 and started a college and residence for women at St. Michael's College in the University of Toronto. The sisters also established many other schools across Canada, both at the elementary and secondary levels.
