The original Roden School consisted of four rooms and was formally opened in April 1908. Five additions were made to the building between 1910 and 1922.
At the time of replacement, the old school consisted of twenty-seven classrooms, two kindergartens, boys' and girls' playrooms, staff rooms, library, offices and health and dental rooms.
In 1966, the Metropolitan Toronto School Board established its study of educational facilities ( S E F ). The aims of S E F were to prepare educational specifications for schools which would accommodate the needs of present and future educational requirements and to prepare technical performance specifications which would result in a building systems approach to school construction.
In early 1968, the Toronto Board of Education was requested to designate Roden Public School-Junior as a S E F test school.
Construction commenced on July 22, 1969 and the cornerstone was laid by Trustee Alex C. Thompson, Q.C., B.A. on December 10, 1969. The new building was first occupied by students on September 8, 1970 and formally opened on November 25, 1970.
