Since the end of the Cold War, competition among states has been waged along economic rather than ideological or military lines. In Canada, as elsewhere, this shift has forced a rethinking of the role of intelligence services in protecting and promoting national economic security. The scholars and practitioners featured here explore the aim, existing mandate, and practical applications of economic espionage from a Canadian and comparative perspective, and present a range of options for policy-makers. Economic Intelligence & National Security examines the laws in place to thwart economic spying, and the challenges and ethical problems faced by agencies working clandestinely to support their national private sectors.
