Rideau High School was an Ottawa-Carleton District School Board high school in Ottawa, Ontario, Canada . It was located at 815 St. Laurent Boulevard in the east end of the city on the edge of Vanier. It was located next to the Queen Elizabeth Public School. History The school opened in 1957 under Principal E. D. Hendry. It was the second of a series of ten high schools built by the local school board to cope with rapidly rising attendance and the baby boom. The project generated some controversy as the Collegiate Board presented a plan that included an auditorium, double gym, and a cafeteria. The Ottawa Property Owners association objected to these as expensive and unneeded luxuries, and the mayor Charlotte Whitton agreed. The dispute delayed the construction of the school for some time. In 1971-72, Rideau High School concert and stage bands produced an album. In an October 6, 2009 report by the OCDSB, closure of the school was recommended, with its current students to be redirected to Gloucester High School. and incoming students to be re-directed to Lisgar Collegiate Institute (English) or Glebe Collegiate Institute (French Immersion). However, due to a vote on December 7, 2009 (wherein the OCDSB board members voted to reject the recommendation), the school remained open. Rideau was designed to hold 800 students. The enrolment fell to about 550 students by 2013, with the rest of the building populated by the children of two day-care programs and an adult English program. In March 2017, the Ottawa-Carleton District Board of Trustees voted to close Rideau High School, effective June 2017, and redirect all of its students and programs to Gloucester High School. The reasons for closure were cited as declining enrollment (student population for 2016-2017 was 413) and the consequent reduction in programming opportunities for students. Architecture Rideau was built at the same time as Laurentian High School and Ridgemont High School and has the same base design by architects Hazelgrove, Lithwick and Lambert with well-lit efficient circulation, and a large auditoria. The double gymnasium block projected into a large sports field and oval track. For adults, commercial and business classes were offered in the evenings. There are tennis courts, a large parking lot, well equipped science labs, technical shops and a library. There are two storey t-shaped wings for classrooms, with the gym, auditorium and cafeteria in bumped out blocks. The building was
