I'm not in favour of introducing the medieval law of banishment into our Canadian legal system, so on general principle, I have serious concerns. Also the door is open in future to parliaments of other countries getting their hands on Canadian citizens. A citizenship bill is now before the Spanish Parliament that will extend Spanish citizenship to people claiming to be Sephardic Jews, and that means that in Canada, following Ms. Seligman's train of thought, if a person is Jewish and has a certificate of being a Sephardic Jew, they get Spanish citizenship. There are unforeseen, unintended consequences here that truly have to be studied at great length before going forward.
