On May 1, 2014, the directors of ADM (Aéroports de Montréal) announced a call for tenders to demolish the Mirabel terminal, putting a definitive end to the passenger transport vocation at this airport inaugurated with great fanfare in October 1975. But what happened? Who is responsible for this mess? Could it have been done differently? Was the best location selected for this airport? Why did we fail to connect Mirabel with a fast train, as originally planned? What about Dorval airport, now Montréal-Trudeau? How much longer will it be able to develop? What happened to the rail shuttle? What does the future hold for both airports? What lessons can we draw from this saga? These are just some of the questions this book seeks to answer.
