In the Canadian criminal jurisdiction for prosecution, the basic principle is territoriality, not personality. We would maintain an ability to prosecute.... I mean, we can prosecute foreigners who commit crimes in Canada. They don't have to be citizens of Canada. We can extradite people from abroad, whether they're citizens of Canada or not, for prosecution here if we have other jurisdictional ties.
Our position is that you do prosecution if you can, but if you can't, then.... I'm not even sure that worrying about maintaining the ability to prosecute is that valuable.
