Perhaps you need to ask Sarah's husband, Rory, how he feels about the non-paying (in this case) Canadian system. But, generally, I agree that comments about the Canadian system are usually positive. Why do you think the Canadians acted so horribly wrong in this particular situation? Have you seen the pics of Sarah on the web? She seems like a happy, friendly, young person. Why would the Canadian authorities and their system single her out to not cover? I don't get it. As you say, Canadians seem to really like their system. Certainly the Canadian public would not approve of this treatment of one of their own.
Note that the article I posted is a UK article.
Remember, we're not talking about the USA health insurance system here. Sarah is a Canadian who held both Canadian coverage (that amazingly did nothing for her - unbelievable) and private coverage that was only for sanctioned events.
