Detention and deportation are the two most extreme sanctions of an "immigration penality" that polices noncitizens, identifies those deemed dangerous, diseased, deceitful, or destitute, and refuses them entry or casts them out. They play a key role in regulating national borders, citizens, and populations. But what determines whether a noncitizen is "deserving" or "undeserving"? And how have anxieties about risky outsiders and the quest for security shaped Canada's response to immigrants and refugees?

Anna Pratt takes a close look at the discursive formations, transformations, and technologies of power that have surrounded the laws, policies, and practices of detention and deportation in Canada since the Second World War. She demonstrates that although the desire to fortify the border against risky outsiders has long been prominent in Canadian immigration penality, the degree to which concerns about security, crime, and fraud have come to govern the process is unprecedented.

Securing Borders traces the connections between seemingly disparate concerns – detention, deportation, liberalism, law, discretion, welfare, criminal justice, refugees, security, and risk – to consider them in relation to the changing modes of Canadian governance.

This work is a rich interdisciplinary study which promises to be of interest to scholars in a range of disciplines including criminology, socio-legal studies, law, history, sociology, political science, international relations, and public administration. It will also be of interest to non-governmental advocates as well as to government representatives who work in the areas of immigration, refugee determination, and related fields.
