WHO vs. Toronto

Brief random thought #1: How come I haven’t heard any serious outrage from the libertarian crowd in the Blogosphere about the WHO travel advisory warning against travel to Toronto (among other places)? A non-elected, unrepresentative international body has by fiat made a declaration affecting the livelihood of hundreds of thousands (millions?) of Canadian citizens. Isn’t that, like, a big deal? (Yes, Samizdatistas, I’m talkin’ to you).
Brief random thought #2: Would Toronto itself, or businesses (or individuals therein) have standing to sue the WHO? In what court — Canadian? Volokhs? Prof Reynolds? Anybody?
