In August 1982, the College signed an agreement to acquire the Mother House of the Sisters of the Congrégation de Notre-Dame in order to unify its fourteen separate locations. The campus opened in 1988, but full consolidation only happened in 1997, when the Selby Campus was finally closed. Extensive renovations transformed the century-old building into an attractive, modern and well-equipped college, occupying an entire city block between de Maisonneuve Boulevard, Sherbrooke Street, Wood Avenue in Westmount and Atwater Street in Montreal. A new theatre space was added to the historic site in 2007 and the College was truly under one dome.
