St. Mary’s High School which had uninterruptedly served the Catholic parishes of Kitchener for 48 years, enlarged its accommodations and added to its curriculum as the need arose and standards of education advanced. But the mounting enrollment figures taxed the second unit beyond capacity, so that an additional building became imperative. Accordingly, the board of Governors, consisting of the pastors of the Twin-City parishes, provided a new building, which, on December 13, 1955, was blessed by his excellency, most Reverend J.F. Ryan, Bishop of the Diocese.
The new building contained 12 regular classrooms, a small library, a principal’s office, 2 teacher’s rooms, and a bright, spacious lower-floor cafeteria able to accommodate 450 persons. The home Economics and Commercial Departments as well as the Science Laboratories were enlarged, equipped and modernized in keeping with the trends in education and business.
No one was happier on this occasion than the principal, Sister M. Loretto, who had served the school for 20 years, first as a teacher, then as a principal. When she was elected Provincial Superior of the school Sisters of Notre Dame in Waterdown, in 1956, Sister M. Stella, the present principal, was named her successor.
