Border officers at one of Canada’s busiest crossings have intercepted one of the larger cocaine loads reported this fall. The Canada Border Services Agency said officers at the Ambassador Bridge port of entry seized 127 kilograms of suspected cocaine from a commercial truck arriving from the United States on September 11.

The seizure, detailed in a federal release dated October 19, has resulted in charges laid by the RCMP. The Ambassador Bridge between Windsor, Ontario and Detroit is the single busiest commercial border crossing in North America, handling a quarter of Canada–U.S. merchandise trade, which makes large concealments in legitimate freight a persistent enforcement challenge.

Federal officials routinely credit secondary inspections and intelligence-led referrals for finds of this size. A load of 127 kilograms would carry a wholesale value in the millions of dollars before being cut and distributed, according to police estimates in comparable cases.

The accused faces prosecution in Ontario. The CBSA release did not name the driver in the summary provided, and the allegations have not been tested in court.
