She isn’t one-dimensional.
Neither is her education.
Trailblazing educators Maud Edgar and Mary Cramp founded ECS on the belief that girls thrive when their education is built around how they learn, lead, and grow. That vision continues to define an experience of exceptional breadth in a warm community, supporting who she's becoming.

A Tier 1 school, ranked among Québec’s top private schools by the Fraser Institute.
Academic Challenge

With girls in 100% of student leadership roles, from prefects to club heads and beyond, leadership is part of everyday school life.

29 student-led clubs and 16 athletics options offer girls opportunities to lean into their strengths and discover their passions.
Signature Programmes
The Entrepreneurial Platform and Learning to Learn (L2L) are among several innovative programmes unique to ECS.
Future-Readiness
