Anybody with money can get top-notch quality care right across the border but isn't allowed to spend that money for the same here at home - unless it's for their pet.  I've read that every Canadian prime minister in modern times, except Harper, has gone to the USA for medical treatment at some point.  I remember QC premier Bourassa got treated for his skin cancer in the USA.

It also helps to have influence here at home.  When was the last time you heard about a Toronto Maple Leaf or Raptor waiting two months for an MRI?
