Cité des Iles was a study proposed to the City of Montreal by Moshe Safdie following the close of Expo '67. The overall idea behind the study was to transform the temporary Expo exhibition site including structures, parks, and transit lines into permanent amenities for the city. The study was well received by many city officials, but did not proceed because of anticipated review complications between the various levels of provincial, federal, and municipal agencies.
