About Us

Founded in 2005, The Duncan Academy (TDA) is a boutique private high school in Ontario, fully accredited and licensed by the provincial Ministry of Education. With an experienced and passionate faculty and well-established programs, TDA serves both local Toronto students and international students. As an officially recognized educational institution, TDA is authorized to grant the credits required for the Ontario Secondary School Diploma (OSSD). Upon completing 30 credits, including 18 compulsory courses prescribed by the Ministry, students are awarded the OSSD. Our five integrated pathways are built around the Duncan Individual Growth Plan, focusing on each student's academic success and long-term personal development. Through our signature arts program and AP/IB curriculum, which provide pathways to leading universities in the United States, as well as our partner online school and after-school support ecosystem, TDA delivers a comprehensive and distinctive educational experience.

Our professional team provides academic and university advising services that help families plan ahead and navigate each stage of the educational journey with confidence. Through Duncan SIS, our modern and user-friendly student information management system, parents can access clear and up-to-date information about every milestone in their child's academic progress. TDA also offers a homestay program to help international students transition smoothly to life in Canada, providing a safe, supportive, and stable environment in which they can focus on their studies.

Five Integrated Pathways

From OSSD credit courses to ESL support and homestay placement, TDA provides everything students need to succeed.

As the core academic platform, The Duncan Academy delivers the main high school curriculum, small-class instruction, academic management, and personalized support. Students build their learning rhythm, complete core credits, and gradually clarify their future university direction.

▶

Toronto Secondary School of Art

TDA's partner art high school, offering a dedicated arts-focused pathway for students passionate about the visual and creative arts, complementing the OSSD academic program.

▶

MayWay AP / IB Advanced Studies

For students aiming at elite universities, competitive majors, and the highest academic challenges, we provide AP / IB enrichment and advanced academic support. Students enter more challenging courses and training tailored to their target direction.

▶

Lumon Online School

A more flexible online course pathway with credit-supplement options. For students who need to adjust their learning pace, make up courses, or expand their course selection, online learning serves as an important complement to in-school study.

▶

After School

Picks up beyond the classroom: homework support, language enhancement, study-habit development, and stage-by-stage academic guidance. It isn't simple tutoring — it makes classroom learning and after-school consolidation a continuous process.

The Meaning of the Educational Ecosystem

The five pathways are not separate, independent programs — together they serve each student's growth journey. Students receive different levels of support at different stages, based on their foundation, learning state, and future goals.

The value of this integrated educational ecosystem is that it does not require all students to follow the same path. Instead, it provides combinations suited to students with different goals.
