Common wisdom suggests that the 9/11 terrorist attacks changed everything about the character of refugee law in the United States and in neighbouring Canada. But did they? If so, how do the responses of the two countries compare in terms of their negative impacts on refugee rights? Refugee Law after 9/11 undertakes a systematic examination of available legal, policy, and empirical evidence to reveal a great irony: refugee rights were already so whittled down in both countries before 9/11 that there was relatively little room for negative change after the attacks. It also shows that the Canadian refugee law regime reacted to 9/11 in much the same way as its US counterpart, and these similar reactions raise significant questions about security relativism and the cogency of Canadian and US national self-image.
