About

Welcome to Markham Secondary School (MSS), a distinguished institution within the Dewey Institute in Toronto, Canada. As an Exam Centre for Cambridge International Education (Centre No. CA104), MSS offers International A-Level courses and a rigorous ESL program designed for talented and ambitious students.

​

At MSS, passion for learning is matched by a commitment to academic excellence. Our students achieve outstanding examination results and progress to world-class universities, supported by dedicated teachers, a vibrant intellectual community, and a culture that values curiosity, innovation, and independent thought.

​

Accessible and inclusive, MSS welcomes both day and boarding students from diverse backgrounds. New pupils join at various stages and are quickly integrated into our friendly community, where peer support, collaborative events, and shared experiences help each student feel at home. Strong pastoral care—delivered by Heads of Year, tutors, counsellors, and our School Nursing Sister—ensures every student is valued, supported, and encouraged to thrive.

​

Beyond academics, MSS offers an exceptional extra- and co-curricular program. Students can explore interests in athletics, creative arts, music, debating, Model United Nations, and numerous inter-school and House activities. This holistic approach helps students grow in confidence, develop leadership skills, and enjoy a rich and fulfilling school life.
