The Federal Aviation Administration lifted a nationwide ground stop shortly after 7 p.m. on Friday, November 14, 2026, ending several hours of halted U.S.-bound flights departing from Canadian airports, including Calgary International Airport (YYC).
Calgary International Airport Experiences Major Flight Interruptions
Calgary International Airport held all U.S.-bound flights for several hours due to the U.S. ground stop caused by an air traffic control telecommunications issue. Passengers waited on board some aircraft before being instructed to disembark, while others remained in the terminal with uncertain travel plans. Naji Zuain, a passenger from Lloydminster, was aboard an Air Canada flight destined for Denver when the delay was announced. After
about an hour on the plane, passengers were told to leave the aircraft. Zuain’s flight was rebooked for 9 a.m. on Saturday, November 15, obligating him to arrange overnight accommodation at his own cost.
Airline and Airport Responses to the Disruption
Air Canada informed affected passengers that it would not cover expenses incurred due to the flight cancellations and delays. Zuain commented that while the situation was unfortunate, he understood the airline’s stance, calling it unfair to hold the carrier responsible for costs related to a disruption beyond their control. Calgary International Airport acknowledged travelers’ patience via a tweet as normal flight operations began to resume following
the FAA’s lifting of the ground stop.
Cause of Ground Stop Linked to U.S. Air Traffic Control System
The cancellations and delays at Calgary International Airport and other Canadian departure points stemmed from a federally mandated nationwide ground stop in the United States. This safety measure was triggered by a telecommunications failure within U.S. air traffic control systems, prompting the FAA to halt all U.S.-bound flights nationwide temporarily. This interruption directly impacted flights originating from Canadian hubs to U.S. destinations, including routes to cities such as Denver.
