A Canadian man and his young son were deboarded from a Orlando-bound flight at Pearson Airport here for allegedly watching a video of the 9/11 terror attacks.
The two were pulled from the Air Canada flight just before takeoff on Tuesday after a fellow passenger alerted the flight crew when he saw the young boy watching the video.
Air Canada officials confirmed the incident.
"Other passengers and our crew became concerned," Air Canada spokesman Peter Fitzpatrick was quoted as saying by the 'Toronto Sun'.
"Safety and security as well as the comfort of all our passengers and crew is always our top concern and we take whatever steps we deem necessary to provide a safe, secure and comfortable environment," he said.
An Air Canada employee said at first the man tried to cover up the video when staff went to talk to him.
Later, the two were freed as Investigators found no criminal offence had taken place.
Peel Regional Police Constable Samantha Nulle said officers assisted the airline with the complaint and met the two passengers when they were taken off the plane.
Nulle said she could not confirm the two were watching 9/11 scenes.
"The two were cleared of all allegations and set out on the next flight," she said.
