The Community Hebrew Academy of Toronto was founded in 1960 by the
Associated Hebrew Schools of Toronto, in whose building CHAT was initially housed, to meet a long-standing need for a comprehensive Jewish high school for students graduating from Toronto's junior Jewish day schools. The founding of the Academy was fraught with controversy, as community leaders struggled to develop a guiding philosophy that would respect various ideologies within the Jewish community. The first Grade Nine class had only three pupils, but subsequent classes grew to full enrolment. CHAT moved to the former Wilmington Public School facility owned by the
Toronto District School Board in 1979. In September 2000, a second campus, called CHAT Richmond Hill, was opened on Wright Street in
Richmond Hill to serve students living north of
Steeles Avenue. In June 2006, it was announced that the school would be renamed the Anne & Max Tanenbaum Community Hebrew Academy of Toronto (TanenbaumCHAT), in honour of a large gift from the estate of Dr.
Anne Tanenbaum. TanenbaumCHAT's north campus moved in September 2007 to the Lebovic Jewish Community Campus on
Bathurst Street in
Vaughan. The Wilmington Avenue location was renamed the TanenbaumCHAT Wallenberg Campus after
Raoul Wallenberg in May 2008, after a school-wide vote, but that name was dropped after the amalgamation of the two campuses in September 2017. On March 6, 2017, it was announced that the northern campus would close and consolidate with the Wallenberg Campus at the beginning of the September 2017 school year. In 2023, amid the
Gaza war, the school received two bomb threats, and three people were arrested outside the school after threatening students. ==Feeder patterns==
