Unusual in banning...

All provinces in Canada provide http://en.wikipedia.org/wiki/Universal_healthcare, publicly funded healthcare for those services which are considered "medically necessary", with their costs partially subsidized by the federal government.
Services which are not "listed" (covered by a provincial insurance plan), or have been "delisted"
(removed from the plan) may be purchased privately.
Compared to other single-payer health systems in the world,
Canada is unusual in banning the purchase of private insurance (Unlike others Canada forbids private insurance?)
or care for any services that are listed. This is meant to prevent what is described as "two-tier healthcare", which would allow the rich to "jump the queue".
