Keystone International Secondary School Toronto

About Us


Differentiated curriculum delivery creates unlimited possibilities.

“Education should not be the filling of a pail, but the lighting of a fire.” 

— W. B. Yeats


Learning happens naturally when it's experienced.

“Tell me and I forget. Teach me and I remember. Involve me and I learn.” 

—Benjamin Franklin


Experience in diverse classrooms lead to an understanding of the world.

“The wise man belongs to all countries, for the home of a great soul is the whole world.” 


WELCOME TO Keystone International Toronto

Keystone International Schools was established in 2012. Keystone follows the Ontario curriculum with a project-based, experiential approach to learning. Keystone serves both international and local high school students in grades 9 through 12 in the heart of Toronto, where students are prepared for post-secondary success. Universities expect students to think about what they learn: understand, analyze, formulate, investigate and propose solutions to non-routine problems. They are expected to be resourceful and connect their learning to real-life issues. They need to organize themselves and manage their time to meet deadlines. At Keystone Toronto, students follow the Ontario curriculum, while learning key self-management skills.  Apart from the core subjects, students pick their electives based on their interest and potential career choices. Selection of electives is a process that involves the students, parents, teachers and guidance counselor. 

Canadian High School Diploma

Upon graduation, students will receive an Ontario Secondary School Diploma (OSSD).
