St. Mary’s High School has undergone many changes throughout its history. From its beginnings as a convent school, St. Mary’s has transformed itself many times. Not only has the focus and purpose of the school evolved over time, so has its physical shape changed.
The evolution of the school has been traced below. But this in no way is a complete history. The full history of the school lives on in the memories and legacies of former students. The spirit and traditions of the alumni continues in the students of St. Mary’s today. We honour the sacrifices and the dedication of the School Sisters of Notre Dame, the founders of St. Mary’s High School.
