From the Introduction: "Transnational Criminal Organizations (TCOs) operating on both sides of the United States-Canada border (Northern Border) often team with criminal biker gangs to exploit the international boundary's vulnerabilities for illegal activities. They smuggle illegal drugs such as heroin, fentanyl, methamphetamine, marijuana, MDMA (ecstasy), and cocaine as well as weapons and the illicit proceeds from drug sales between the two countries. [...] To address the unique threats associated with the United States-Canada border, the 'Northern Border Counternarcotics Strategy' ('Strategy') further refines the 'National Interdiction Command and Control Plan' ('NICCP') and the 'National Drug Control Strategy' ('NDCS') and supports the United States-Canada Joint Action Plan to Combat Opioids, by establishing the Administration's strategy to prevent the illegal trafficking of drugs across the U.S.-Canada border, as mandated by the Congress in 21 U.S.C. § 1705(c) (3)(C). This 'Strategy' reflects the longstanding tradition of close collaboration between the United States and Canada with regard to our 5,225-mile shared border--the longest in the world between two countries."
