The Greater Toronto Airports Authority (GTAA) is apologizing for last week’s disruptions at Toronto’s Pearson International Airport.

On Wednesday, GTAA board chairman Vijay Kanwar said the agency, which manages Pearson, would like to “sincerely apologize” for the inconvenience passengers experienced during a ground stop due to the extreme cold.

The ground stop at Pearson was implemented on Jan. 7 after wind chill readings hovered around the -40 C mark, preventing North American flights from landing at Pearson for around 11 hours.

Kanwar said the ground stop was implemented for the safety of employees, passengers and the public, and that it was carefully considered and reviewed with the GTAA’s partners.

He said a special committee will be conducting a review of the incident, which is expected to be completed in 90 days. The findings will be shared with the public.

Kanwar also said the board is committed to reviewing airport operations and to take action based on the review’s findings.
