If that meeting ends at 5 p.m., we will have to fly back to Montreal, stay overnight and, the next morning, make the trip between Montreal and Baie-Comeau.
Si la réunion se termine à 17 heures, il faut reprendre l'avion, coucher à Montréal et, le lendemain matin, faire le trajet Montréal Baie-Comeau.
