At the beginning of the 21st century, as global flows emanate from North America and from all around the world to stream across our continent in every direction, the enhanced border between Canada and the United States of America appears strangely enigmatic. Due to the immense pressure on the one hand to step up security, and the almost equally strong imperative on the other to expedite crossing, the border has been re-invented to enable the rapid crossing of some goods and services, and some people (Konrad and Nicol, 2008; Brunet-Jailly, 2007).
