Montreal airport sees continued flight cancellations Saturday after Friday’s U.S. ground stop

Montreal-Trudeau International Airport remained affected by travel disruptions on Saturday, following a nationwide U.S. Federal Aviation Administration ground stop issued on Friday that halted departures to the United States. CityNews Montreal reports that travelers faced ongoing cancellations and delays as operations continued to ramp back up after the FAA’s action was lifted later Friday evening. The disruptions at Montreal-Trudeau were tied directly to the U.S. halt, with the airport noting that flights to and from the United States were temporarily suspended and travelers were urged to check with their airlines for status.

According to CTV News, about 40 flights were canceled at Montreal-Trudeau International Airport on Saturday as operations resumed after the FAA’s temporary ground stop, which had suspended U.S.-bound flights on Friday. The FAA lifted the suspension after 9 p.m. local time, enabling airlines to resume departures to the United States, and airport authorities indicated that aircraft unable to land in Montreal on Friday could not depart on Saturday, contributing to the cancellation tally. Airport guidance urged travelers to verify status with their airlines.

CTV News also noted that the nationwide FAA ground stop was described as immediate and nationwide, affecting all departures across U.S. airports due to reported air traffic control communications issues described as extraordinary circumstances and safety concerns. The suspension was said to affect international arrivals on a case-by-case basis as the FAA continued its investigation, with updates anticipated as root causes were explored. The Montreal disruption is described as the Canadian reflection of that U.S. action.

In its coverage, CityNews Montreal added that the FAA’s action led to a broad pause in U.S.-bound flights, and that airlines were resuming activity gradually after the stop was lifted. An airport spokesperson mentioned that the temporary suspension had delayed or canceled several departures and arrivals, and that passengers should verify status with their airline. The report did not provide specific flight numbers or destinations affected at Montreal.

Winnipeg Sun provided additional context, characterizing the FAA action as a nationwide ground stop caused by congestion in air traffic control routers and switches, contributing to thousands of flight cancellations and delays across the United States, with limited direct impact described for Winnipeg. The piece indicated the action occurred on Friday and described its broader infrastructure-driven basis, noting no detailed breakdown of affected flights or carriers within the supplied material.

CityNews Calgary offered parallel reporting, stating that YYC Calgary International Airport had initially blocked all U.S.-bound departures during the FAA-wide pause, with later updates reflecting changes after the stop was lifted. The Calgary coverage aligned with other outlets in describing the stoppage as temporary and tied to safety-related communications issues within air traffic control centers. Airport advisories urged passengers to monitor status and contact airlines for specific flight information, noting that the disruption affected U.S.-bound travel and was evolving as the FAA investigation continued.
