Ongoing flight delays in Calgary due to air traffic control outage


Flights are delayed at Calgary International Airport this morning due to a breakdown in the airport’s navigation system.

An airport spokesperson confirmed to CBC News that a system outage with Nav Canada has resulted in ongoing issues.

There is also an ongoing problem with WestJet’s self-service bag drop, although earlier nationwide issues with infrastructure and online payment services have been resolved.

Self-service bag drop does not work properly in Calgary as well as in Ottawa, Saskatoon and Halifax.

“Customers are encouraged to arrive early and check flight status before heading to the airport,” read a statement posted by the airline on its Twitter feed.

Nav Canada, which operates the country’s air navigation system, said the disruption was caused by one of its telecommunications service providers, Zayo. According to Nav Canada, Zayo estimated a recovery time of two to four hours at around 8:30 a.m. MT.

“Ensuring the safe movement of air traffic through Canadian airspace is Nav Canada’s top priority,” Nav Canada spokesperson Brian Boudreau said in an email.

“As such, air traffic control will temporarily reduce the flow of departures and arrivals in certain situations until Zayo has restored service. Procedures are in place to ensure the safety of aircraft in our airspace. “

The airport spokesperson said further updates will be provided as they become available.

A spokesperson for the Greater Toronto Airports Authority said the outage only appears to affect Western Canada, adding that operations at Toronto Pearson Airport are normal.
