Instances of security, terrorism, or people who wish Canada harm are sometimes associated with national profiles but are basically concerned with individuals. We have decided, through long and hard policy thought, to make visas necessary for some countries and to make other partners visa-free. I think only a historical analysis can justify those decisions. Our track record is pretty good. Our experience, prior to the lifting of the visa with Taiwan, was that it was not problematic.
