The TanenbaumCHAT (Community Hebrew Academy of Toronto) Alumni Association encourages all TanenbaumCHAT Alumni to maintain a life-long association with their high school and provides opportunities for alumni to support the school and its students.

TanenbaumCHAT Alumni return to the school as mentors and mentees for the Alumni Mentorship Network and as speakers for Career Day. They reunite with their class at regular reunions and to play basketball for The Alumni Basketball Tournament, Settle the Score.  Alumni also support the school by giving to the Annual Fund and participating in special campaigns and fundraising efforts.
