A storm passing through Montreal caused power interruptions Wednesday afternoon at Pierre Elliott Trudeau International Airport and the Réseau express métropolitain.
The airport reported around 3:30 p.m. that the outage had been resolved and systems were being progressively restored.
Flights were still taking off and landing at the airport during the outage, which affected “some IT systems” and “various areas of the airport,” though several flights were cancelled or delayed because of the weather.
The airport asked passengers to check the status of their flight with their airline.

In the West Island, the REM was also without power Wednesday afternoon. According to the REM website, there was an outage between Bois-Franc and Anse-à-l’Orme stations at 2:13 p.m., expected to last until 4:30 p.m.
According to Hydro-Québec’s outage tracker, more than 32,000 addresses in Montreal were without power as of 2:30 p.m., but that number had dropped by more than half within the next half hour. At 3:30 p.m., only 8,000 Montreal addresses were still without power.
“Lightning triggered protection devices on the electricity transmission network in the west end of Montreal, leaving nearly 30,000 customers without power, including Montreal Airport and the REM light rail system,” Hydro-Québec said in a statement. “Our teams are working to restore service as quickly as possible. We apologize for the inconvenience and thank you for your cooperation. Thunderstorms still ongoing in southern Quebec could cause further outages, and we have mobilized all necessary teams.”
