Registering at St. Mary’s

Students currently attending WCDSB elementary schools will register online using CareerCruising during January. Grade eight teachers will assist you through this process. WRDSB elementary students please request the necessary forms from your teacher or guidance counsellor.

Students currently attending another high school within Waterloo Region and wishing to transfer to St. Mary’s should contact their guidance counsellor for a Principal to Principal Transfer request. Transfer for students living outside of the St. Mary’s boundary will be considered only under very rare extenuating circumstances and must be approved by the principals of both schools.

Students who have moved into St. Mary’s boundary from outside of Waterloo Region, please contact the guidance department at 519-745-6892 – extension 5632 – to arrange an appointment to register.
