Faulty equipment in an “incredibly old” telecommunication system may have caused an air traffic control issue, U.S. Transportation Secretary Sean Duffy says.
In a press briefing on Saturday, he said a contractor was doing routine maintenance to upgrade copper wire to fibre optic cable when something went wrong.
Officials are now investigating whether the error was due to “incompetence” or a “faulty router,” he added.
Bryan Bedford, administrator of the U.S. Federal Aviation Administration added that U.S. air travel should be back to normal by the end of Sunday.
This is just the second nationwide ground stop in the United States since the Sept. 11, 2001, attacks.

‘We had to wait for news’
Isabelle Rochefort said she had been standing in line at Montreal’s Trudeau International Airport to board her Air Canada flight to Cancun, Mexico, around 5 p.m. Friday when she received word that it was cancelled.
She said the situation was initially confusing because her plane wasn’t touching down in the United States.
“We didn’t know what to do, of course,” she said in a series of Facebook messages.
“The Air Canada staff had no information on what was next except that we had to wait for news.”
She’s since been rebooked on a new flight leaving Sunday, though she’ll have to pay for yet another expensive ride to the airport.

Sports teams’ travel impacted by stop
Major sporting events slowly returned to normal Saturday after the U.S. Federal Aviation Administration grounded all flights nationwide for several hours a day earlier, disrupting travel plans for professional and college teams across the country.
Most college football teams playing Saturday travel the day before kickoff, and a number of games were delayed by hours to give visiting programs more time to arrive and prepare.
There were 14 scheduled NHL games on Saturday, and the majority made it to their destinations before the flight stoppage began. The San Jose Sharks, who were left waiting to see whether they would be able to travel, arrived late Friday in Utah.
In the NBA, most teams were, at worst, mildly affected by Friday’s events. Cleveland was the outlier. The Cavaliers started their Saturday much earlier than usual, leaving Miami at 8:54 a.m. on a plane taking them to Cleveland -- where they were set to play the Dallas Mavericks on Saturday night.
The NFL benefitted from its Sunday slate, as teams typically travel the day before their games.

‘It’s crazy’: Traveller
Traveller Edward Langer, who is in New York with his 15-year-old daughter, said his Saturday flight back home to Edmonton was postponed by about four days due to the freeze.
He said he and his daughter are facing several missed days of school and work, as well as thousands of dollars in extra hotel costs.
He had not been able to reach Porter Airlines as of Saturday afternoon despite spending hours on hold.
“When you go on some of the travel sites to book hotels, (the price) is just doubling and tripling,” he said.
“It’s crazy.”
Canadian travellers miss start of cruise
Nancy Jackson and Janet Bell are not happy after their flight to Los Angeles was cancelled, resulting in them missing their cruise.
“We’re very unhappy. We understand that things happened in the States yesterday with the airspace, but we are booked to go on a cruise today, leaving L.A. at 3 p.m., but of course we’re not going to make it,” Jackson told CP24 during an interview at Toronto Pearson International Airport.
She said Air Canada cancelled their 8 a.m. flight and rebooked them with American Airlines, which was eventually also cancelled.
They have now booked a flight to Los Cabos via Dallas to catch up with the cruise.
“We’re just out hundreds, if not a couple of thousands extra, to try and get five days on a seven-day cruise,” Bell said.
Both have expressed their frustration with the customer service they’ve received from the airlines.
“It’s a nightmare,” Bell said.
“Do better. When something like this happens, have more customer service representatives available so the wait times on hold are not that long.”
Nancy Jackson and Janet Bell say their flights to the U.S. were cancelled today as airlines continue to grapple with the impact of the ground stop order. CP24
Airports, airlines issue travel notices
Some Canadian airports and airlines spent Saturday issuing travel notices and catching up on a backlog left behind by a freeze on U.S. air traffic.
One of Canada’s largest airports, Toronto Pearson International Airport, said it called in more staff to help out with the day.
“A busy day of travel is underway at Toronto Pearson,” it said in a social media post early Saturday.
Calgary-based WestJet said in a separate post that it was responding to a significant travel disruption, while Porter Airlines said it would likely take the whole weekend for its flights to return to normal schedules.
A Porter Airlines spokesperson said in an email that it would refund its customers who can’t accommodate rescheduled flights.
Airports in Vancouver, Edmonton, Calgary and Halifax issued travel notices and asked travellers to double-check their flight statuses before leaving their homes.
N.L. local airport was ready to receive diverted passengers
Reg White, chief executive of the airport authority in Gander, N.L., said he called the local hotels for vacancy numbers and made sure the restaurant could stay open if planes were diverted to the town.
White said there was some relief when the so-called ground stop was lifted Friday night without any diversions to Gander.
The people of Gander famously cared for thousands of passengers stranded in the town when planes were grounded after the Sept. 11, 2001, terrorist attacks in the U.S.
White said he didn’t brace for an onslaught of planes on Friday because there were no flights between Gander and the United States, nor was it a peak time for flights between the U.S. and Europe.
The systems were ‘overwhelmed’
In the Q&A following the press meet, U.S. Transportation Secretary Sean P. Duffy told reporters that the FAA had deployed their smart system to better navigate weather and trajectories for flights. But the system that was to blame for the disruptions was not connected to it.
“Smart had zero impact on the occurrences yesterday,” he said.
U.S. FAA Administrator Bryan Bedford told reporters that “nothing went down.”
“What we saw was instability. We couldn’t explain the instability. We saw the instability start to propagate into facilities we couldn’t identify,” he said. “That’s when we made the decision to ground stop out of our abundance. No facilities went dark. Nothing was fully boxed.”
Bedford added that the pressure “overwhelmed one set of routers in an in-facility, which then went through the backups at other facilities, and it propagated from there.”

‘Zero evidence’ of nefarious or AI-related issues
In the same press conference, U.S. FAA Administrator Bryan Bedford told reporters that the system had started displaying “instability” which they were unable to access, at which point they implemented the ground stop.
“We did that because we felt it was helpful to remove pressure from the system… holding airplanes on the ground while we continue to work through the root cause analysis of the instability in the system, and ultimately to relieve stress and complexity in the airspace,” he said.
Bedford added that at the time of the ground stop, nearly 30,000 flights were either on the ground or in air, and 20,000 remained. The FAA was ultimately able to recover only around 8,000 of those flights.
Based on word from airline partners, they believe they will be back to “full schedule integrity” by Sunday, he said.
“I do think the worst is behind us, but we still do have a significant amount of recovery work to do with our airline stakeholder group,” the FAA administrator said, adding that they have identified the fault and had “zero evidence” of any nefarious or AI-related activities.

A few days to destination: Expert
Speaking to CP24, aviation management expert John Gradek said the disruption would take several days to unwind and reach back to normal.
While some flights might resume normal operations today, passengers whose trips were cancelled could wait until Monday, Tuesday, or Wednesday for available seats, he said.
He estimated around a million passengers were affected and explained that airlines must use “optimization and re-optimization” to get the right crews and aircraft to the right places in the right order.
“It does require a lot of calculations and a lot of mathematics to make sure that you get the right crews on the right airplanes at the right time at the right place,” he said.

Not a cyberattack: Duffy
U.S. Transportation Secretary Sean P. Duffy told reporters that they don’t believe it was a cyberattack from any foreign nation or otherwise.
“Once we were able to isolate the work that was being done at this remote location, all of our systems came back online,” he said. “So, we don’t believe this was cyber at all, this was an FAA system that didn’t meet the moment.
“Our contractor didn’t meet the moment, or the equipment didn’t meet the moment and caused the outages,” Duffy added.
The U.S. FAA is working toward “modernizing air traffic control,” the U.S. transportation secretary said, adding that the resources provided are not enough.

Work to replace old copper wiring to blame?
U.S. Transportation Secretary Sean P. Duffy told reporters Saturday that there was an issue with an old copper wire in “an incredibly old telecommunication system,” which was being replaced, that caused the disruption in the flight radar feeds.
“In at least one of our remote FAA locations, a contractor was doing routine maintenance to switch telecommunication lines from old copper wire, and they were bringing it over to fiber,” Duffy said.
“The work happening was due to the age of the copper wire that we were replacing. It was such an old wire that it was being discontinued, meaning that line was going to get shut down,” he continued.
The U.S. transportation secretary added that the U.S. FAA may have been the last one to be making this switch from copper to fibre due to lack of investments.
“What we’re working to determine was whether we had incompetence: meaning was it user error or installation error from L3 Harris (the contractor), or did they install a faulty router? We haven’t determined what the fault was,” Duffy said.
“Either through contractor error or a faulty piece of equipment, the router that was being replaced as we switched from copper to fiber… it started flooding other routers in our air traffic control system.”

40 flights cancelled at Montreal-Trudeau International Airport
The Montreal-Trudeau International Airport said 40 flights were cancelled Saturday as operations resumed after a Federal Aviation Administration (FAA) ground stop temporarily suspended flights on Friday.
Airport authorities said airlines resumed flights to the U.S. after the FAA lifted the temporary suspension of flights after 9 p.m.
“Aircraft that were unable to land in Montreal yesterday cannot depart today, which explains these cancellations,” a Montreal airport spokesperson told CTV News Saturday.
“We encourage travelers to check the status of their flight with their airline before heading to the airport.”
On Friday, 61 flights were cancelled, including 32 arrivals and 29 departures, as a result of the ground stop.

‘Additional cancellations’ Saturday, Air Canada says
Air Canada cancelled around 250 flights on Friday, affecting approximately 27,000 passengers, an airline spokesperson says.
In a statement on Saturday morning to CTV News, Yasmine Medhi said there have been “additional cancellations” and that it will take time to return to “normal operations.”
“To help alleviate the situation, we have added extra flights where possible to increase capacity and accommodate affected passengers,” the statement reads.

Operations ‘slowly’ returning: Duffy
U.S. Transportation Secretary Sean Duffy says flight operations are “slowly returning to normal” as of Saturday morning.
In an X post, he added that there will still be some delays and cancellations as carriers “reschedule flights and reposition” aircraft and crews.
“Our top priority right now is making sure travelers get home safely to their families as quickly as possible,” the post reads.
He added that officials will share more updates at 10:30 am ET this morning.
Airlines not required to offer additional compensation
An FAA computer problem is considered outside the control of the airlines — much like the weather.
The only thing the airlines are obligated to do is to offer free rebooking on another flight for travellers that want to continue to their destinations or a refund if their flight was canceled and they decide not to take the trip.

Pearson will be in ‘recovery mode’ Saturday: spokesperson
It is going to take some time for airport operations to resume as normal, Pearson spokesperson Erica Vella says.
She notes that it is still unclear if U.S. flights are going to resume this evening as the situation remains fluid.
“But we are working very, very closely with our airlines, and we will be moving into a bit of a recovery mode today and tomorrow to make sure that airlines can get their schedules back on schedule and make sure that passengers can get to their destinations,” Vella told CTV News Toronto.
She added that the airport’s emergency operations centres will remain activated while the airport moves into recovery mode.

Mexican singer stranded after Latin Grammys
Singer-songwriter Vivir Quintana was stuck in Las Vegas the day after performing at the Latin Grammys, upending plans to return to Mexico City for a performance Friday evening.
She was supposed to join Majo Aguilar as a guest artist for their performance at the country’s national auditorium.
“We’re waiting for our suitcases — hopefully this can get resolved — but right now, all we can really do is breathe and be patient,” she said. “She’s performing there for the first time tonight — her very first time at the auditorium. My family will be there, so I’m sad about that.”
Flight disruptions to continue: Pearson
Toronto Pearson International Airport says U.S. flights will continue “to experience disruptions and cancellations as airlines work to restore normal flight schedules,” despite the ground stop order being lifted.
The airport is advising passengers to keep checking the status of their flight directly with their airline before travelling to the airport.
No guarantee scenario won’t repeat itself: Duffy
“Is this exact thing going to happen again?” U.S. Transportation Secretary Sean Duffy told reporters. “I don't—I don’t know that this exact scenario will happen.”
Duffy also repeatedly called on Congress to authorize billions of dollars in spending to modernize federal aviation safety.
“And so I would say, America, Congress, let’s make this system more safe,” Duffy said.
Delays may continue: NAV Canada
NAV Canada says it will continue working to keep air traffic moving in Canadian airspace after the FAA lifted the ground stop order.
“Some delays may continue while operations return to normal and backlogs are cleared,” NAV Canada said in a post on social media.
It reiterated that passengers should check their flight status with their airline.
Getting planes back in air will take time: official
At the time of the ground stoppage, there were 3,500 airplanes in the sky.
“And last time I looked, we had less than, 400 in the airspace,” said U.S. Transportation Secretary Sean Duffy.
“It’s going to be slow” getting air traffic back to normal, he added.
Ground stop strands Toronto couple
Toronto-area couple Lyle Jakobsen and his wife were supposed to fly back from Sint Maarten this afternoon when their Air Canada flight got cancelled.
“We boarded. Everything was fine. In probably 10 minutes after boarding, we got a notification that we would be delayed. There was the FAA issue, so we sat on the tarmac for, I would say, probably the better part of an hour and 15 minutes,” Jakobsen told CP24 on Friday night.
“The pilot kept us up to date while we were on the tarmac.”
Passengers were then deboarded, and Jakobsen said he was able to find a hotel where they could stay.
Air Canada has said that flights from the Caribbean and South America that have to pass through U.S. airspace would be impacted by the ground stop.
“Air Canada has been very communicative with us, and we’re happy with that for sure. So, what one more night in Saint Martin is probably not the worst scenario,” Jakobsen said, adding that he hopes that they get to fly back to Toronto tomorrow.

College football teams prioritized ahead of games
The ground stoppage left dozens of U.S. college football and other sports teams stranded or unable to depart for their weekend games.
“I would encourage those football teams to reach out to the FAA, to schedule their flight times and make sure they can move” to make their kickoff, U.S. Transportation Secretary Sean Duffy said.
Barbados flight ‘indefinitely cancelled’: traveller
A traveller who was set to fly out of Barbados to Toronto said she got the news her flight was cancelled when her plane was on the runway ready for take off.
Dominique Franklin spoke to CTV News Channel on Friday, sharing how she is stuck in Barbados as a result of the FAA grounding flights in U.S. airspace.
The flight crew said they were unable to access radar and radio to safely fly the plane, Franklin reported.
“I went straight to the WestJet desk,” she said, after she and her co-passengers left the plane.
“The only update that they were able to give us is to really just keep checking your email and we hope to be out to Toronto tomorrow morning.”
Franklin says she will sleep in half-hour increments tonight so she can check her email.
No evidence of cyberattack: DHS
“There was never any lives at risk,” U.S. Homeland Security Secretary Markwayne Mullin said. “There was no flights at risk. FAA was able to handle it. We did it out of an abundance of caution.”
Mullin sought to downplay conspiracy theories about what caused the outage.
“I do understand the internet traffic, and where all these conspiracies are running towards,” he said.
Ottawa updates U.S. travel advisory
The federal government updated the safety and security section for the United States on its travel advisory website Friday.
It states that the FAA issued a nationwide ground stop for all U.S. airports, and that travellers can “expect air travel disruptions.”
It advises travellers to contract their airline for more information on how the grounding will impact travel plans.
Passengers should check with airlines
Erica Vella, a spokesperson with the Toronto Pearson International Airport, says the situation is “very fluid.” She reiterated what airport officials have been saying all night: that passengers should check directly with their airlines about their flight status.
“At this point, we know that flights from Toronto Pearson to the U.S. are being impacted right now. There’s over 100 U.S. flights that have been cancelled at this point,” Vella told CP24.
“We are telling passengers to make sure that they are checking their flight status and to not come to the airport if they do not have a confirmed booking.”
She noted that 20 other international flights have also been cancelled as a result of the ground stop order.
“We’re monitoring developments as well from the FAA, so we’re able to adapt and be able to address issues should they arise.”

Hundreds of U.S. flights cancelled at Toronto’s two airports
Hundreds of flights have been cancelled at Toronto’s two airports after the FAA issued a ground stop order on Friday, leaving many passengers scrambling.
The Greater Toronto Airports Authority, which operates Toronto Pearson International Airport, said in a statement that there were no scheduled U.S.-bound departures or arrivals at this time
“Passengers are advised to check directly with their airline for the latest flight information before heading to the airport.”
The GTAA noted that international and domestic flights that do not require transit through the U.S. airspace will continue to operate.
Meanwhile, Toronto Billy Bishop Airport said that Air Canada and Porter Airlines have cancelled all remaining Friday U.S.-inbound and outbound flights.
Minnesota flight cancelled: Regina airport
The Regina International Airport says it is monitoring local impacts as the United States grounds all departing flights nationwide.

Canada to provide ‘full assistance’ to FAA: Minister
Transport Minister Steven MacKinnon says Canada will support the U.S. aviation authority.
“Canada has offered its full assistance to the Federal Aviation Administration (FAA) as it manages the situation, including accommodation of U.S.-bound aircraft as required,” MacKinnon wrote on X.
He added that he remains ready to support U.S. aviation authorities moving forward.
Pearson Airport provides update on non-U.S. flights
Toronto Pearson Airport says international and domestic flights that do not require transit through the U.S. airspace will continue to operate.
“We are increasing staffing across the airport to assist affected passengers. Our support teams are being deployed throughout the terminals, with additional resources available in the U.S. departures area,” Pearson said in a post on social media.
“We are also working closely with airlines and have implemented a parking plan for aircraft.”
More than 100 flights to and from the U.S. have already been cancelled at Pearson tonight.
Communication issues don’t appear linked to new FAA system
The communications problems that led to the nationwide halt to flights don’t appear to be linked to the FAA’s new AI-powered system the agency is rolling out to help predict problems in the sky.
The FAA’s SMART system is based in a single location near Washington, D.C., where a team of experts analyzes flight schedules, weather forecasts and hundreds of other streams of data.
Then that office sends recommendations to the FAA’s command centre that relays them to controllers across the country for consideration.
The company that designed the system, ASI, said “the current ground stop is not based on or a result of the SMART system, any product of ASI or our integration with FAA and ATC.”

U.S. ground stop throws sports world into chaos
The FAA's decision to ground all flights nationwide Friday threw the sports world into chaos, leaving NBA and NHL teams stranded as they tried to reach their destinations, and NFL teams were left to wonder whether the issue would be resolved in time for them to travel to their games this weekend.
The Nets were among five NBA teams scheduled to fly Friday for games on Saturday. They had just boarded the team plane in New Orleans after playing the Pelicans earlier this week when their flight to Memphis was halted in place.
The Pistons flew earlier in the day to Miami. The Cavaliers, Bulls and Grizzlies play Friday night and were due to fly afterward.
There are 14 scheduled games in the NHL on Saturday. And while the Panthers made it to St. Louis for their game before the stoppage began, the Sharks were among those that were left waiting to leave for their game in Utah.
The FAA did not provide a timeline for restarting flights, leaving sporting events taking place beyond Saturday in limbo. That includes most of the Week 10 schedule in the NFL.
Caribbean, South America flights may be affected: Air Canada
Yasmine Mehdi, an Air Canada spokesperson, said the ground stop is affecting flights to and from the United States. She said flights to and from the Caribbean and South America may also be affected.
"Any flights currently airborne have been advised they are permitted to continue," said Mehdi. "We are monitoring the situation very closely and will provide updates as they become available."

‘Traffic management measures’ at Canadian airports
NAV CANADA, the country’s air navigation authority says it is “implementing traffic management measures” at major airports as a result of the FAA grounding U.S. flights.
The measures will help manage traffic at Toronto Pearson International Airport (YYZ), Montréal-Pierre Elliott Trudeau International Airport (YUL), Calgary International Airport (YYC) and Vancouver International Airport (YVR), the agency said in a post on X.
“Travellers should expect delays and check with their airline,” NAV CANADA added.
Pilots trained how to handle losing communications: expert
Aviation professor Skip Bailey said the reason they teach them that is so they will be prepared if the radio on their plane malfunctions. He said no one expects air traffic controllers nationwide to lose the ability to communicate.
Pilots are expected to maintain the headings and vectors that controllers gave them before the problem. And then if the outage continues, they revert to following their filed flight plan. Pilots may also be able to communicate with each other over the radio even if they can’t talk to controllers. And airliners have their own radar systems.
“It’s not mass chaos out there. There’s plenty of ways to try to communicate,” said Bailey, who teaches at the University of Nebraska at Omaha’s aviation institute. “But not letting anybody take off again obviously is extremely important because we don’t want to put more aircraft into a system that’s already having an issue.”

Pearson passengers wait for flight updates
A number of passengers flying to the U.S. at Toronto Pearson Airport are still waiting for updates from their airlines about their flights.
Donna, who is flying to New York City for the weekend, says her flight has been rescheduled for tomorrow.
“I was really hoping to fly out tonight. So, it’s a bit of an unfortunate situation,” she told CP24.
“Definitely very disappointed that my plans for the weekend have been cancelled, or at least very delayed.”
Derek is supposed to fly to Las Vegas and says Air Canada has told him to “stick around.” However, he is not optimistic that he’ll get to his destination.
“It’s most likely going to be cancelled. And even if you’re rebooked till tomorrow, it’s unlikely. So, I think you’re going to have people with a lot of refunds,” Derek said.
Shahab Mirmiran came to Toronto on Monday for work and is hoping to get back to Los Angeles tonight.
"Unfortunately, we don’t know what’s going on. I have to go. I need to do something for work,” he said. “They’re just saying you have to wait.”
Another man who arrived from London, U.K., says he's waiting to hear about his connecting flight to Raleigh, N.C.
“It stinks, but just holding off for a little bit and seeing what happens,” he said.
