Oh, about rationing and elderly (from Mythbusting Canadian Health Care Part II):
Another persistent (and ridiculously mendacious) rationing myth about the Canadian system is that old people are cut off from treatment and left to die. I've never heard about a single case of this in Canada; but it happens routinely to Americans on Medicare and many private policies, which have strict limits on how long you can stay in the hospital with an acute illness. When the benefits run out, ready or not, they send you home. If you die, you die. The Canadian plan has no such limits: you stay for as long as you need to. But in the US, these limits fit the very definition of "rationed care."
