This study is based on open source research into the scope of Asian organized crime and terrorist activity in Canada during the period 1999 to 2002, and the extent of cooperation and possible overlap between criminal and terrorist activities in that country. The analyst examined those Asian organized crime syndicates that direct their criminal activities at the United States via Canada, namely crime groups trafficking heroin from Southeast Asia, groups engaging in the trafficking of women, and groups committing financial crimes against U.S. interests. The terrorist organizations examined were those that are viewed as potentially planning attacks on U.S. interests
