Changing of the Guards evaluates issues of privatization and private influence across the twenty-first-century Canadian criminal justice system. In recent decades, service outsourcing has spread throughout Canada’s prisons and jails, into its police, courts, and national security institutions, and along the border. The employment of private security guarding has been a well-documented trend since the 1960s, but the expanding scope and changing shape of corporate involvement in other criminal justice functions across Canada has not been closely investigated. Until now. This assessment illuminates the serious consequences of public–private arrangements for law and policy, transparency, accountability, the administration of justice, equity, and public debate. Within the contexts of policing, sentencing, imprisonment, border control, and national security, contributors ask critical questions about legitimacy, policy diffusion, racism, inequality, corruption, and democracy itself. Their trenchant analysis raises key empirical, theoretical, and policy questions that are relevant not only in Canada but also abroad. While privatization and private influence in the US and UK criminal justice systems have received much attention, Changing of the Guards is a long overdue examination of the social, political, and historical aspects of these processes in the Canadian context. This comprehensive volume will interest scholars and students in criminology and criminal justice in Canada, as well as international scholars in these fields. It will also appeal to those in sociology, political science, policy studies, law, critical security studies and surveillance studies.
