Police investigating a suspicious package found at Toronto's Pearson International Airport say the bag contained items for routine tests of security checkpoints.
Peel regional police say in a tweet that the items were most likely ``left by an airport partner after being used,'' but did not specify exactly what those items were.
Police say they received the call about a suspicious package at Terminal 1 by an airport employee at about 8:45 p.m. Wednesday.
Level 3 of the terminal was shut down for about four hours as police investigated.
Airport officials said domestic and international passengers were being processed in other parts of the terminal.
