This article appeared in Homeland Security Affairs (2007), Supplement no. 1Land border crossings between Canada and the United States are a critical component of Canada's modern trade routes, representing a vital strategic link to the economic viability of Canada. A catastrophic terrorist event at the Canada- United States border would be an event having the potential to seriously disrupt those economic linkages, vital to the well-being of Canadians and the Canadian state. The outcome of a catastrophic terrorist incident along the border could impact Canada in a number of ways. This paper will look at two issues with regards to the border and terrorism, and briefly discuss the impact on Canada specifically, and Canada-United States relations indirectly. Those two issues are border infrastructure as the target of a terrorist attack and the potential for the transnational movement of terror groups for the purpose of delivering an attack.Approved for public release; distribution is unlimited
