The high school is located on the upper level of the main school building. As a registered and inspected school with the Ministry of Education in Ontario, our students are able to obtain the Ontario Secondary School Diploma (OSSD). The Collegiate offers over sixty courses, mostly at the academic and university or university/college level. Our focus is on the core subjects, but we also offer a wide range of options including three modern languages and classical Greek and Latin. Our graduates have attended and do attend universities across Canada, the United States, Europe, and the Far East. Bi-annually, high school students can participate in a major dramatic production. Students participate in achievement tests and university-sponsored competitions. See Collegiate Handbook for specific details.
