Since the events of 9/11, even the most genteel of borders, such as the Canada/US border, have witnessed an increased preoccupation with exclusionary practices, virulent applications of risk management, and a general embrace of biometric and Radio Frequency Identification (RFID) technologies focused on identity management of varying forms. As a result, the border has been further securitized and in some regards, even militarized.Although strengthened borders and the intensified securitization of migration related to these changes in border security are relatively well documented, such accounts tend to argue that borders are "thickening." Specifically in the Canada/US case, the notion of a thickened border post-9/11 is nearly prosaic. While not altogether rejecting the metaphor of the thickened border, there is something more complex afoot. Rather than simply making the border more difficult to cross, the invocation of specific technologies-namely biometrics and RFID-which are contextualized within a near obsessive application of risk management by the
