Peel police are investigating after a trailer containing about $50,000 worth of milk was stolen in Mississauga on Thursday.

Around 6 a.m., the refrigerated trailer and hitch of a transport truck was taken from a parking lot near Airport Road and Steeles Avenue East.

Police found the trailer hours later, but wouldn’t confirm whether there was still milk inside.

According to the Insurance Bureau of Canada (IBC), cargo theft costs the Canadian economy $5 billion each year and often goes unreported.

The IBC said organized crime syndicates steal the trucks or trailers, offload the cargo, parcel it and sell it for a quick profit, often before the crime is reported.

Last weekend, a tractor-trailer containing an estimated $100,000 worth of blueberries and some fruit was stolen in Hamilton.

The truck was recovered but the trailer and the blueberries are still missing.

Transportation hubs in southern Ontario, Montreal and Vancouver are prime targets for the low-risk, high-reward crime, the IBC said.
