U.S. and Canadian authorities monitored the Lynden, Wash.-Aldergrove, British Columbia tunnel's construction for months before moving in and shutting down the drug trafficking operation it supported in July 2005. The U.S. Drug Enforcement Administration arrested three Canadians from Surrey, British Columbia.
