We need to have the act, though, or something, simply to determine, first of all, whether the person is a Canadian citizen, so we don't have non-Canadian citizens trying to come to Canada. Secondly, we have to make sure it's an offence in both countries. Obviously if somebody is given the death penalty in the United States, we can't administer that sentence in Canada.
The sentence and the offence, the double criminality principle, which is in international law--we have to at least meet those, so the person isn't coming to the border saying “I have my right to enter”, but they're asking to come back to serve their sentence. We have to have some control because they're coming into our correctional facilities. There has to be some communication, and so on, in relation to that in order to facilitate the transfer.
