The authors of the article about the Canadian system in Forbes are conservatives with the Fraser Institute and ideologically disposed to moving Canada's system to a free-market system. No one pays attention to them and the scenarios they paint are not representative. Canadians overwhelmingly support their health care system. You also cited an article from 2007. This was during the campaign to delegitimize the Canadian system as part of the Republican strategy to push back on Obama's health care reform, which naturally brought Canada into the conversation. It is well documented that Republicans recruited ideological malcontents from Canada to write extremely biased articles about the Canadian system as part of their negative campaigning and even got them to go to your country to spread their lies. 

I didn't bother reading the other two articles. I live here and know the system inside out and you're full of it as usual.
