Don Bosco Catholic Secondary School

Don Bosco Catholic Secondary School (also called Don Bosco, Don Bosco CSS, DBCSS, Don Bosco Toronto, or simply Bosco), is a Toronto Catholic District School Board secondary school facility in the city of Toronto, Ontario, Canada. It is located in the former suburb of Etobicoke, north of the intersection of Islington Avenue and Dixon Road in the Kingsview Village neighbourhood.

The school opened in 1978 by the Salesians of Don Bosco religious orders as Central Etobicoke's first Catholic high school and moved into the former Keiller Mackay Collegiate Institute building, constructed and opened in 1971 by the Etobicoke Board of Education, in 1983. Don Bosco became fully publicly funded by the Metropolitan Separate School Board in 1987. Many years later, the board closed Don Bosco due to dwindling enrollment in 2017 and the building became the temporary home for the Toronto Argonauts practice facility, with a short-term lease of the facility from the TCDSB. After its vacancy, the school building is used to house Dante Alighieri Academy starting in 2021–22 school year as their school is being reconstructed.

In the school's later years, Don Bosco became famous for then-Mayor Rob Ford's football program.
