At the turn of the century, the attention of the U.S. security establishment has been drawn to the consideration of non-traditional and asymmetric threats to the continental United States. Consequently, there have been calls for the development of new strategies and structures aimed at assuring the defence of the 'homeland'. Several measures have been undertaken. Others are contemplated. Given the circumstances of North American geography and the nature of its relationship with its southern neighbour, this issue and these actions are of great interest to Canada. This paper examines the Canadian security environment with a view to determining to what extent such threats confront Canada. It concludes that significant threats - while perhaps less acute in certain dimensions - do indeed exist. What then is Canada's policy? What should it be? To answer these questions, this essay proposes an ends, ways and means based Canadian homeland security strategy.
