A major disruption to North American air travel brought flights between Canada and the United States to a standstill on Friday, November 13, 2026, after the U.S. Federal Aviation Administration ordered an extraordinary nationwide ground stop.

Toronto Pearson International Airport and Montréal-Trudeau International Airport suspended flights to and from U.S. destinations as American authorities investigated a widespread air traffic control communications failure.

The unprecedented disruption left thousands of travellers facing cancellations, uncertain departure times and missed connections. Although Canadian air traffic control systems continued operating normally, the interconnected nature of the two countries’ aviation networks meant Canadian airports could not escape the consequences.

With U.S. officials unable to immediately provide a firm timeline for restoring normal operations, the shutdown raised fresh questions about the reliability of America’s aging aviation infrastructure.

What Triggered the FAA’s Nationwide Ground Stop

The crisis began Friday afternoon when the FAA reported serious communications problems affecting air traffic control facilities across the United States. At approximately 3:54 p.m. Eastern Time, the agency issued a nationwide ground stop, instructing departing aircraft to remain on the ground. The emergency notice cited extraordinary circumstances and safety concerns. The problems reportedly affected communications at the country’s 22 regional air traffic control centres, which coordinate aircraft travelling between major airports.

Importantly, the order did not mean every aircraft already flying over the United States was forced to land immediately. Thousands of flights already airborne were permitted to continue toward their destinations under controlled conditions, while new departures were halted to prevent additional pressure on the system. International flights were being assessed individually. The distinction mattered for Canadian travellers, particularly those connecting through American airports. A flight already approaching its destination could potentially land, while another aircraft scheduled to depart minutes later might be unable to leave its gate.

Toronto Pearson Suspends Flights to and From U.S. Airports

Toronto Pearson International Airport, Canada’s busiest aviation hub, was among the major Canadian airports affected by the American shutdown. The airport reported the suspension of flights to and from U.S. destinations, disrupting travel plans for passengers heading to American cities or returning to Canada. The restrictions were particularly significant for travellers with connecting itineraries, where even a relatively short interruption could make an entire journey impossible to complete as scheduled.

The scale of the disruption becomes clearer when considering Pearson’s normal passenger volumes. According to the Greater Toronto Airports Authority, approximately 47.3 million passengers travelled through Pearson in 2025, including 10.4 million connecting passengers. The airport functions as a major transfer point for travellers moving between Canada, the United States and overseas destinations. For someone flying from Toronto to Europe through an American hub, a grounded first flight could jeopardize the entire itinerary. Meanwhile, arriving aircraft, airport gates and airline crews could become increasingly difficult to coordinate as schedules deteriorated throughout the evening.

Montreal-Trudeau Airport Confirms U.S. Flight Suspensions

Montréal-Trudeau International Airport also confirmed that flights between Montreal and American destinations had been suspended until further notice. In a public statement Friday afternoon, the airport authority warned passengers to expect cancellations and delays and encouraged travellers to check directly with their airlines before heading to the airport. The announcement came as the U.S. shutdown spread beyond American borders, affecting airlines that rely on American airports and airspace to maintain their regular international schedules.

Montreal’s connection to the American aviation network is substantial. Aéroports de Montréal reported that 22.4 million passengers travelled through Montréal-Trudeau in 2025, with approximately 4.7 million passengers using transborder services. Even though U.S. passenger traffic declined compared with the previous year, American destinations remain a significant part of the airport’s operations. A Friday afternoon suspension also creates complications for travellers planning weekend departures, particularly those with prepaid accommodations, onward connections or events scheduled shortly after arrival. For airlines, restoring service involves more than simply receiving permission to depart, as aircraft and flight crews must also be available.

Canada’s Air Traffic Control System Remains Operational

Despite the widespread disruption, Canada’s air navigation service provider, NAV CANADA, confirmed that its systems were operating normally. The organization said it was continuing to manage Canadian airspace safely and remained capable of handling aircraft that might need to divert from the United States. This distinction is important because the American ground stop did not represent a nationwide closure of Canadian airports or a technical failure within Canada’s aviation infrastructure.

Nevertheless, Canadian airports depend heavily on coordination with American air traffic controllers, particularly for cross-border flights and international routes that enter U.S. airspace. Even a fully functioning Canadian system cannot independently authorize aircraft to operate through restricted American airspace. Ottawa International Airport also reported impacts on U.S. arrivals and departures, while officials anticipated that some aircraft might need to divert. The situation demonstrated how aviation disruptions can cross international borders without the original technical problem occurring in both countries. Domestic Canadian flights were not automatically subject to the FAA’s nationwide order, although airline schedules could still experience secondary delays if aircraft or crews became unavailable.

Communications Failure Raises Questions About Aviation Safety

American officials identified a telecommunications failure affecting air traffic control operations as the immediate reason for the shutdown. U.S. Transportation Secretary Sean Duffy said FAA technicians were investigating the problems, while Homeland Security Secretary Markwayne Mullin emphasized that authorities had not found evidence of a deliberate attack. Investigators had not established the precise technical cause. Although questions emerged about the FAA’s recently introduced artificial intelligence technology and a separate Microsoft service outage, neither connection had been established, and the companies involved said they had no indication their systems were responsible.

Air traffic control depends on reliable communications between pilots and controllers to maintain safe separation between aircraft. When essential communications become unreliable, authorities must limit the number of planes entering affected airspace. The FAA’s decision to halt departures was therefore a preventive safety measure rather than evidence that thousands of aircraft were immediately in danger. Aviation specialists explained that established procedures allow pilots and controllers to manage certain communications failures, but widespread problems create challenges that cannot be resolved by individual aircraft crews alone. The shutdown illustrated why redundancy and dependable communications infrastructure are essential to modern commercial aviation.

Thousands of Flights Delayed or Cancelled Across North America

The consequences of the ground stop spread rapidly through the American aviation network. Flight-tracking data cited by Business Insider showed more than 3,220 cancellations and approximately 10,200 delays involving flights to, from or within the United States by about 6:40 p.m. Eastern Time. Earlier, Reuters reported that 4,042 aircraft were already airborne and bound for American airports when the nationwide ground stop was announced. Those aircraft could continue landing, but the inability to launch new departures created an increasingly serious scheduling problem.

For travellers, the disruption meant more than watching departure times change on airport monitors. Passengers already seated aboard aircraft could be returned to terminals, while others faced long waits at customer-service counters. Reuters described congested departure areas and aircraft unable to reach gates because departing planes remained parked. The effects could persist after the original technical problem was resolved. Commercial airlines operate tightly coordinated networks in which aircraft routinely fly several routes each day. If one plane cannot complete an afternoon journey, its scheduled evening service may also be affected, potentially leaving passengers stranded hundreds or even thousands of kilometres from the original disruption.

What Canadian Travellers Can Expect From Airlines

Passengers affected by cancellations or lengthy delays have protections under Canada’s Air Passenger Protection Regulations, although the circumstances surrounding this particular disruption matter. Because an FAA communications failure would ordinarily be considered outside an airline’s control, passengers generally would not qualify for the standard cash compensation awarded for certain airline-caused disruptions. However, airlines still have rebooking obligations. Canadian regulations generally require carriers to offer affected passengers available alternative flights, with additional refund or rebooking rights when suitable transportation cannot be arranged within the prescribed period.

For flights covered by U.S. Department of Transportation regulations, passengers whose flights are cancelled are entitled to refunds if they decline alternative transportation, regardless of the reason for cancellation. Canadian travellers should check their airline’s website or mobile application for updates before leaving for the airport. Those already travelling should retain receipts for unexpected accommodation, meals and transportation expenses, particularly if they have travel insurance. Passengers should also review their complete itinerary before accepting changes because cancelling one segment independently could complicate existing connecting reservations. A delayed flight does not automatically entitle someone to a refund if they ultimately take it.

When Will Flights Resume, and Could Disruptions Continue Into the Weekend?

As of Friday evening, American authorities had not established a firm timeline for restoring normal air traffic operations. The FAA’s nationwide ground stop was expected to remain in effect until at least 11 p.m. Eastern Time, although that did not guarantee departures would resume at that hour. Even after communications systems were restored, airlines would need to reposition aircraft, reorganize flight crews and accommodate passengers whose original flights could no longer operate. Aviation analysts warned that an extended shutdown could create disruptions lasting through the weekend.

The crisis also revived concerns about America’s aging air traffic control infrastructure. The previous nationwide departure halt occurred in January 2023, when a malfunction in the FAA’s Notice to Air Missions system interrupted flights across the country. That ground stop lasted less than two hours, but its consequences continued after departures resumed. Congress approved $12.5 billion in 2025 for air traffic control improvements, and the White House requested another $30.1 billion on November 13, 2026, for aviation modernization and airport infrastructure. For Canadian travellers, the immediate priority remains the restoration of safe and predictable cross-border flights. For policymakers, the larger challenge is preventing a communications breakdown in one country from repeatedly disrupting air travel across an entire continent.
