Founded in 1957 as the Foundation Day School at the Beth Tzedec Synagogue, it was renamed United Synagogue Day School in 1961. One of the largest Conservative Judaism schools in the Solomon Schechter Day School Association, USDS has an enrollment of about 900 students. It is the second largest Jewish elementary day school affiliated with Toronto's UJA Federation Board of Jewish Education and is one of the largest feeder schools for the Community Hebrew Academy of Toronto. In 2010, after an endowment, the school changed its name to Robbins Hebrew Academy, as a condition to accepting the endowment, by Larry Robbins. It is the only Jewish Day School in Toronto to be CAIS (www.cais.ca) accredited.
