The Toronto District School Board (TDSB; known as English-language Public District School Board No. 12 prior to 1999) is the English-language public-secular school board for Toronto, Ontario, Canada. The minority public-secular francophone (Conseil scolaire Viamonde), public-separate anglophone (Toronto Catholic District School Board), and public-separate francophone (Conseil scolaire de district catholique Centre-Sud) communities of Toronto also have their own publicly funded school boards and schools that operate in the same area, but which are independent of the TDSB. Its headquarters are in North York. The TDSB is Canada's largest school board and the fourth largest school board in North America.
