Peel regional police inspector Stephen Duivesteyn said the cargo was reported missing after being unloaded from a plane Monday evening. He added that cases such as this one are "very rare."
"Subsequent to its arrival this high-value cargo was removed by illegal means from the holding facility," said Duivesteyn.
No one has been arrested yet.
"We're three days in, so our investigators have their eyes open to all avenues," said Duivesteyn.
