No. The fare is only valid on STM bus line 747. It cannot be used on any other bus or other modes of public transit (metro, train, REM, paratransit).
Once aboard the 747 bus, upon presentation of an activated “YUL Aéroport Mtl-Trudeau” digital fare, the driver will visually validate the fare and give you a transfer that will allow you to travel by bus, metro, train and/or REM throughout the Montréal agglomeration (zone A) for the next 24 hours.
