List of secondary schools in the Toronto District School Board

This is a list of secondary schools in the Toronto District School Board. The board is Canada's largest school board and governs 110 secondary schools, as well as five adult education schools. The TDSB was created in 1998 following the merger of the Board of Education for the City of York, the East York Board of Education, the North York Board of Education, the Scarborough Board of Education, the Etobicoke Board of Education and the Toronto Board of Education.

In secondary school, students may enter three general streams based on their goals upon graduation: academic for students planning on attending university, applied for students planning on attending college, and locally developed for students with special needs who are planning on entering the workforce.

• A collegiate institute provides secondary education with all types of subjects available (Arts, Tech, French, etc.) from grades 9–12 levels. University, college, and open streams are available at these institutions. In addition to Collegiate Institute, secondary instutitons of this nature may also go by the name Academy, Collegiate and Technical Institute, Secondary School, or Technical School.
• Several secondary institutions may have a stronger academic focus on a subject then most other schools as a specialized component. The school board operates several art-specialized secondary schools, typically called School of the Arts or School for the Arts.
• An alternative school may be for students who are at risk or failing, or may refer to schools that focus on independent study and are structured like a university. In some cases, the EdVance or diploma program is served to 18- to 20-year-olds who are out of or returning to school similar to a collegiate level.
• For adults over 21 who are returning to school or improving their skills, adult learning centres are offered.
• A Safe and Caring School is a special program for suspended or expelled students who are out of school or at-risk for improper behavioural issues at their home school.

Some schools in the TDSB offer specialized programs to provide particular opportunities and to provide a focus on a variety of interests. Each specialized program has specific requirements as well as unique admission criteria.

• Africentric Secondary Program: Students are given an alternative way of learning in some of their courses through an Africentric lens.
• Arts Focused Schools/Arts Program: Special programs offer a focus on the arts.
• Entrepreneurship: A special program that develops the innovation, flexibility and self-reliance required to be successful in a business-driven environment.
• Centre of Innovation for Skills and Technologies (CIST): Customized learning hubs focusing on science, technology, engineering and mathematics (STEM). Students focus on engineering design process through real-world applications with the goal of preparation for university level studies.
