It should be noted in this thread that the Supreme Court of Canada ruled unconstitutional the charge of "spreading false news" of which Zundel had been convicted by an Ontario court.
He eventually ended up in Germany after agreeing not to fight a deportation order.
Another fact based link on the law under which he was convicted and sentenced in Germany. I'm wary of Wikipedia as well but there's nothing politicized with this description:
