TORONTO — A 58-year-old American man was charged Thursday after a security breach at Canada’s busiest airport that caused lengthy delays for a group of passengers.

Peel Regional ****** Const. Mark Fischer said the ******** took place at Toronto’s Pearson International Airport and involved a United Airlines flight bound for Chicago.

Fischer said officials found what they believed to be an improvised ********* device in the man’s suitcase.

****** said tests determined the device was not *********, but passengers spent hours waiting to continue with their flight.

****** said Joseph Galaska is charged with one count of mischief and was being held for a bail hearing at a Brampton, Ont., court.

Transport Minister Marc Garneau said Thursday afternoon that Transport Canada will be looking into the ********.
