It's one thing for a Judge to exile him. It's another entirely to exile him TO CANADA. Exile to Canada has some implications about our country I don't like; that we would overlook the offence and allow him in, that we would somehow be bound to enforce the US order of "not leaving Canada for three years", and that we have been considered as a dumping ground for a convicted American criminal.
I hope he will not allowed to enter Canada even on a temporary basis. As for his family being here...I can't imagine his wife wanting him around after this either.
