A tractor-trailer shipment labeled as cement was seized at the Peace Bridge this week when border agents discovered 2,959 pounds of marijuana inside the containers, according to Customs and Border Protection.
The rig, driven by a 45-year-old Canadian man, was attempting to cross into the United States on Wednesday, the agency said in a news release Friday.
The shipment manifest listed the contents as cement, but when officers inspected the dozen wooden pallet boxes, they found vacuum-sealed packages of marijuana, authorities said.
Agents seized the marijuana and the driver was denied entry into the country. He was sent back to Canada pending further investigations, the agency said in the release.
The street value of the marijuana was estimated at more than $6 million.
