David and Mary Thomson Collegiate Institute

David and Mary Thomson Collegiate Institute is a semestered English-language high school located in the Bendale neighbourhood in the Scarborough district of Toronto, Ontario, Canada, originally sanctioned by the Scarborough Board of Education and since 1998 under its successor board, the Toronto District School Board.

From 1959–60 until the 2018–19 school year, Thomson was housed in the Lawrence Avenue East building constructed in 1958 and the new school building was built in the former Bendale Business and Technical Institute property in 2019. The school was named after David and Mary Thomson, the first European settlers that immigrated to Scarborough in the late 18th century. Its motto is Nil Sine Magno Labore.
