Standards for health care that the provinces must meet are set federally, and a lot of money that goes into health care is federal
To be clear, there are no federal standards for healthcare that provinces "must meet". Such mandatory standards would likely be unconstitutional as usurping provincial plenary power over "Property and Civil Rights in the Province", as described in more detail
in my previous post.
It is true, however, that the federal government transfers money to the provinces from time to time. If a province's healthcare system does not meet certain standards, then, after certain procedural steps are satisfied, the federal Governor in Council "
may" reduce those transfers "by an amount that the Governor in Council considers to be appropriate". Canada Health Act, RSC 1985, c C-6 ("Act"), § 15. However, the making of such an order is a purely discretionary decision; the Governor in Council is not
required to take any action at all if a province falls below the standards of the Act. On its face, the Act does not create any rights enforceable by persons other than Governor in Council.
Theoretically, if a province's healthcare system has fallen below the standards of the Act and the Governor in Council declines to make an order under Act § 15, a person with standing might be entitled to bring an application for judicial review of the inaction of the Governor in Council under § 18.1(2) of the Federal Courts Act, RSC 1985, c F-7, which authorises the Federal Court to "order a federal board, commission or other tribunal to do any act or thing it has ... unreasonably delayed in doing". However, the courts have traditionally been reluctant to order the Governor in Council to exercise discretionary powers, preferring instead to rely on "a comprehensive system of public and Parliamentary accountability as a substitute for judicial review" if one exists, i.e. the electoral process.

For those reasons, if somebody has a complaint with how they are being treated relative to a provincial healthcare system, their only effective legal remedies, as opposed to political remedies, are likely to lie under provincial law. This is also reinforced by the premable to the Act, which recites that "it is not the intention of the Government of Canada that any of the powers, rights, privileges or authorities vested in ... the provinces under the provisions of the Constitution Act, 1867 ... be ... abrogated or derogated from or in any way impaired".
I have read the healthcare laws of every province (although not in detail) and I can confirm that they are significantly different from each other. I do not propose to describe the differences in this post as it would be too much work.
