Why is Medicare a valued social program (Canada) ? What are the concerns with the current Medicare system?

the medicare is valued by its equality of attention independent of the social class of the citizens. The poor population has high quality in the treatments of their diseases, even without being able to pay for it.

One of the concerns is about what is considered a disease worthy of treatment? Each province in Canada is responsible for its own medicare, but in a provicia autism is not considered a disease that needs treatment. In another province, there is no treatment for fertility, because this is not considered a disease.
