Canada Among Nations has been published by faculty from Carleton University's Norman Paterson School of International Affairs for several decades. This year's edition focuses on national security in the 21st Century. Bringing together emerging and senior scholars, and serving and recently retired practitioners, the volume examines great power competition, the Indo-Pacific, Canada's alliances, the Canada-United States relationship, national defence, and intelligence. The book further explores broader national security concerns, including Arctic security, natural disasters and emergencies, pandemics and public health, right-wing violent extremism, hostile activities of state actors, cyber security, migration, and organized crime.
