Maybe the Canadian health care system is full of problems, but your quote that "I have known a sick man who left his country [Canada]"  to come to the US for medical care is virtually identical to quote from a Shona Holmes (or Lindsay McCreith) who claims the same thing. In fact, Shona was diagnosed with Rathke’s cleft cyst, which is benign and "not typically life-threatening," according to the Mayo Clinic." Silverhorn, I doubt you ever knew such a person as you claim. Instead I believe  you are quoting (on purpose or inadvertently) from an ad produced by  Americans for Prosperity, a Right Wing, corporate funded mouthpiece that churns out arguments so that anti-government conservatives have talking points. It's even from 2009, meaning 7 years old.
