In April 1970, the official design for complexe Desjardins was unveiled at the Montreal City Hall. The entire development, owned jointly by the Corporation immobilière Place Desjardins (51%) and the Société immobilière du Québec (49%), would consist of a basic structure including several floors surrounded by three office towers and a prestigious hotel. The heart of the structure would house a public plaza where socio-cultural and education activities would be held on a daily basis. The building would ... include underground parking that could hold up to 1000 vehicles, movie theatres, and a shopping mall with about 100 shops, cafés and several restaurants.
