The issue is really that it does not seem to be really protected other than certain political realities. There was an understanding in the US that Roe vs Wade was settled law, for example. But it was built on somewhat uncertain legal grounds and you can see what happens with political maneuvering. While it might be political suicide in Canada right now, sentiments and political landscapes could change. I think there is a consensus that decisions should be kept out of courts and remain an issue of health care. That may make sense assuming that folks are sensible. However, in recent times, politics is starting to creep into health care. The issue is on many levels, including the replacement of provincial health care leadership with political figures who have implemented regulations and procedures which the actual providers call bonkers, to put it mildly. As the world seems to be infatuated with being stupid, I would therefore not take prior precedent as a given.
