We had exactly that situation very recently in terms of the reimposition of certain visa requirements on Mexican nationals to Canada, where there was a vigorous internal debate on precisely this sort of trade-off. Ultimately, this gives the Minister of Foreign Affairs a stake on both sides, because the Minister of Foreign Affairs can ultimately make the trade argument, and the Minister of Foreign Affairs would also have the opportunity to list a country.
The listing regime is important, because we've been very poor in the last 20 years in anticipating the evolution of the international security environment. In a case of a rapid degradation of the international security environment, where the government feels it might need to take fairly aggressive, rapid measures to protect Canadians, Canadian interests and Canadian institutions, this is an important tool that we will—not “may” but “will”—regret within your and my lifetimes if it is not inserted into the bill.
