I mentioned three broad principles that I think should inform any truly effective and secure immigration policy. One of them is that the law should facilitate maximum awareness of not only who is entering the country, but, and this is critical, of who is travelling between Canada and those regions of the world with which terrorism dangers, as I said, are most closely associated.
As I mentioned, there is a huge and growing amount of travel between the U.K. and Pakistan, which has been tied to some significant security issues for the U.K. Something similar should at least be on the radar of both the U.S. and Canada with respect to militants from Canada and from the U.S.—not necessarily new immigrants, some of these are even second-generation Americans or Canadians--travelling back to Somalia, equipped with a U.S. passport or a Canadian passport, to earn some credible experience in a very real battlefield in Somalia. The danger is that they could return.
The second thing the immigration laws have to support is an awareness of not just who is coming to the country but of who is leaving the country, and when are they coming back? I think there is probably some considerable room for improvement, not just for Canada but for all countries that are perhaps targets for terrorist groups.
