The school was opened by the Commission scolaire Jérôme-Le Royer for the 1972-73 school year in a rented building at the corner of Aimé-Renaud Street and Metropolitan Boulevard.

Since the school was located in what was supposed to be a temporary rented facility, conditions were less than ideal.

When Doran closed in 1980, the Commission scolaire Jérôme-Le Royer saw an opportunity to get some proper facilities and leased the building from the PSBGM.

The Dunton building was a great improvement for Aime Renaud, as it had been built as a proper high school facility, with an auditorium, a real gymnasium, science labs, a music room, a library and a football field.

It was close to Honoré-Beaugrand station on the Montreal metro and was across the expressway from a shopping centre, Place Versailles.
