Well, global angry traveller, it appears you missed the part where I mentioned I'd understand refraining from travel if you were elderly or immuno-compromised. Why would you chance it, you ask? Yes, why indeed.
That there is a single person in Ontario who is suspected to have contracted the virus, and is currently isolated and in stable condition suggests that well yeah, they do have this under control. The reference to "useless government advice" betrays an attitude that relies upon personal hunch & fear rather than expert professional assessment. The leap to a defensive position implies that you might not be in robust health, and if that's the case, stay home or go to a hospital. Do not go anywhere near an airport. If you are in normal health, you should have little to be concerned about regarding this new virus. That's not my advice (as I wrote in my post, yet feel it's clearly necessary to repeat for you); it's the advice we received in this afternoon's briefing from PHAC and the quarantine nurses. It's literally their business, so maybe direct your vexation their way.
