The government of Quebec has implemented a curfew between 8:00 p.m. and 5:00 a.m. until February 8, 2021. During the curfew, it is forbidden to leave your homes except in cases that justify travel such as taking a plane or to go, following your trip, to your destination.
For passengers, travel to or from airports is therefore authorized during curfew hours. Please have your travel documents such as your plane ticket on hand to justify your travel during a police check.
For more information, see the Québec government web site or the Québec government decree.
