Operations at Pearson Airport’s Terminal 1 were temporarily suspended for what the airport said was a “containment issue.”
Pearson Airport responded to a number of tweets just after 8:30 a.m. from frustrated passengers complaining about the lack of movement through security lines at the terminal.
“This delay has occurred due to a security issue, which is currently being investigated,” read one response.
In another tweet the airport said it was dealing with a “containment issue” that affected flights to the U.S. from Terminal 1. Some passengers were forced to deplane.
U.S. flights at Terminal 3 were not affected.
About an hour after the delay began, the airport tweeted that the containment issue had been resolved without providing any further details as to what led to the delay in the first place.
Peel Regional Police said the issue was due to three people who were not completely screened as they passed through U.S. customs. They were located, screened and allowed to continue on their way. Police said no charges would be laid and there was no risk to the public.
