However, at a certain point in time, a certain number of square meters of Mirabel airport were closed down because the space was not used and therefore it was no longer profitable, and flights were rerouted to Dorval, where it was decided that some 40,000 square meters' worth of facilities hd to be built.
Cependant, à un moment donné, on décide de fermer X mètres carrés de l'aéroport de Mirabel parce que cet espace est inutilisé et que ce n'est plus rentable, et on achemine désormais les vols en direction de l'aéroport de Dorval, où l'on décide de construire des installations de 40 000 mètres carrés.
