"Through successful binational fora such as the Cross-Border Crime Forum (CBCF) and Project North Star, the United States and Canada have increased intelligence-sharing and joint training opportunities for law enforcement officials. Investigative cooperation has also been expanded, through the establishment of new Integrated Border Enforcement Teams and notable enforcement initiatives such as Operation Sweet Tooth/Project O’Skillet and Operation Triple Play/Project O’Slider. The result: greater success in seizing illicit drugs crossing the U.S.-Canada border and apprehending those that traffic them.
"Despite our best efforts, drug trafficking still occurs in significant quantities in both directions across the border. The principal illicit substances smuggled across our shared border are MDMA (Ecstasy), cocaine, and marijuana."
