St. Mildred’s-Lightbourn School
Where inspired girls become empowered women
As the premier independent girls’ school west of Toronto, St. Mildred’s-Lightbourn School has established a 135-year legacy of academic excellence – in a community designed entirely for how girls learn best. Here, we combine a rigorous educational foundation with thoughtful, human-centred use of technology and a supportive environment that inspires students from JK through Grade 12 to challenge boundaries, express their voices, and lead with absolute confidence.
Nestled on a breathtaking 10-acre campus in the heart of Olde Oakville, SMLS has dedicated itself to a singular, profound mission: understanding exactly how girls learn best, and providing them with an environment where they can thrive. Each girl’s journey is personalized, and she is encouraged to explore her unique passions, develop her full potential, and gain the resilience needed to thrive in an ever-changing global landscape.
At the core of the SMLS experience is small classrooms and an uncompromising focus on academic excellence. The Reggio Emilia-inspired approach in our Junior School lays a foundation for curiosity and self-awareness. As girls move into Middle School, they begin to test their strengths and build resilience through reach-ahead academics, leadership opportunities, and co-curricular experiences. By Senior School, students are encouraged to take on deeper learning – developing critical thinking skills and studying university-level material to earn advanced standing at post-secondary institutions.
The forward-thinking curriculum includes three unique Signature Programs designed to bridge the gap between classroom theory and real-world impact:
• STEM and Robotics: Inspiring future innovators, including SWAT 771 – the first all-girls competitive robotics team in Canada.
• Global Citizenship: Expanding perspectives through local trips, service learning, and international travel and studies.
• Professional Internships: Placing all Grade 11 students directly into corporate and community workplaces.
In this all-girls setting, students occupy every single leadership role, voice their perspectives without fear, and mentor fellow students. Deeply supported by an award-winning faculty of experts in girls’ development and a dedicated Student Success Centre, graduates are fully equipped for higher education. The proof is in the results: the 41 graduates in the Class of 2026 secured over 265 offers of admission from the world’s leading universities.
Yet, ask any alumna – affectionately known as a “Millie” – and she will tell you that the true magic of this prestigious school lies in its warm community. It is a lifelong network that provides mentorship and professional opportunities long after graduation.
Choosing a school is about choosing who your daughter will become. Give her the gift of an education where she is encouraged to take bold risks and discover her true potential.
Inspired Girls. Empowered Women. Since 1891.
