Given the significant increase observed in recent years in terms of the number of travellers passing through Montréal–Trudeau International Airport, Aéroports de Montréal (ADM) wanted to revise its planning study related to airport parking supply and demand. This exercise was also justified by some major projects, including the Réseau express métropolitain (REM), the redevelopment of infrastructures by the City and the optimization of alternative transportation services. ADM retained the services of CIMA+ to carry out this revision over a 48-year project horizon (2018-2065).
