NAV Canada says ‘resource constraints’ caused flight delays Saturday at Pearson

By Canadian Press on November 1, 2025.

TORONTO — Canada’s air navigation service provider says flights were delayed Saturday at Toronto’s Pearson International Airport due to what it called “resource constraints.”

A tweet from NAV Canada said that some flights at the airport were delayed, and that its team was “moving aircraft safely, and as quickly as possible.”

Passengers were advised to check the status of their flights with their airline.

NAV Canada did not say in the social media post what the “resource constraints” were, and the Canadian Press has reached out to the company for more information.

Air Canada said on X that the NAV Canada issues were causing delays and cancellations across the airline’s network.

The website for Pearson showed most arrivals at the airport were expected to be delayed until close to midnight on Saturday, and while most departures also appeared delayed earlier in the evening, planes seemed to be taking off on time after 8 p.m. local time.
