Why are republicans Scared of Canadian Health Care?

I used to work for a radiologist in Minneapolis from 1994- 2003 and we recieved patients with referrals from canadian doctors all the time. It was common. And the guy I worked for wasn't even tops in his field. What they were coming for were the same-day MRIs and CAT scans. People who may have cancer cannot wait 6 months for an MRI.
