Trafalgar Castle School helps girls build an education and a sense of self-confidence that will serve them for years to come.

Trafalgar Castle is a place like no other—one that cultivates skills, ignites curiosity and brings your daughter into her own, whether she is an artist, an athlete, an intellectual, or a little of each. Capable and confident, our graduates are exceptional young women who know without question that their possibilities are endless.

Located in Whitby, Ontario, a suburban setting with a close proximity to Toronto, a city that is one of the world’s most internationally diverse, Trafalgar Castle School is a small close-knit all-girls day and boarding school for grades 5 through 12.

Small schools have a way of producing big results; small girls’ schools compound that advantage and then some. We are passionate about knowing each and every student and from this bedrock premise build a foundation that opens up every possible university option.

With over 140 years of education expertise, Trafalgar Castle School excels in educating young women for success at the university level and beyond. Selected from the best curricula from around the world, our internationally acclaimed programs provide an enriching learning environment for our students. Our “world-best curriculum” includes Little Red Schoolhouse—University of Chicago Writing Program, Latin, Robotics, London, Music, and Singapore Math and Science. In addition, the I3 (I-Cubed) Initiative is transforming the way that Trafalgar students learn by creating a context for the application and exploration of knowledge in real-world settings. Building on the rigor and diversity of the School’s world-best curricula, students are guided to ask “wicked questions” and attempt to answer them through experiences beyond the Castle walls. The program strives to help students make meaningful connections between their courses and the wider world and increase their confidence, capacity and adaptability.


Our classrooms are just the beginning. At Trafalgar, we offer a full life outside of the classroom, knowing that, for girls, taking risks and trying new things builds resilience and self-esteem—those key characteristics that will carry them through the toughest times. Whether it’s athletics, the arts, community outreach or peer support, we have something to offer you at the Castle. At our school, these programs are the fundamentals: the outcome is extraordinary.

Boarding at Trafalgar Castle School is available for girls in grades 7 through 12. Trafalgar Castle residence is a home away from home that provides an essentially different experience, because students and teachers interact in significant ways both in and out of the classroom. Learning is not limited to academics; learning takes place after class, in the residence, in the gym, and during play and leisure.

Our boarders at Trafalgar Castle School come from many different countries. There are also many Canadian boarders who reside in other parts of Ontario. This vast diversity in the boarding population creates an opportunity for all the students to learn about other cultures and beliefs.

Trafalgar alumnae are leaders in business, science, technology, the arts, and philanthropy. Our alumnae play a vital role in your daughter’s Trafalgar experience.

Education has never been more prized than it is today and we invite you to learn more about our school and a singular 140 year old tradition that has contributed so much to generations of young women.
