 When Scarborough became a part of Toronto in 1998, the Scarborough Board of Education became part of the new, but one of the largest boards on the continent, the Toronto District School Board.Changes in the new funding structure caused the creation of a short-list of 138 schools in Toronto proposed to be closed.The list was a reaction to a creation of a funding formula based on students per square footage of the school, which prompted debate over the issue rather than the actual closure of the schools.
