This ruling reinforces the division of powers, as health care is a provincial power. This could impact all provinces and the Canada Health Act. We may see a small role back of Socialism in this country.
I hope this helps change the course to socialist ruin but I am not so confident.
Apart from simply tossing their hands up and letting a private care system develop, there are several courses of action it would seem for the governing powers. They can throw more money at it to claim they are fixing the waiting list issue, thus eliminating the need for private care raised in this suit. This would kick the issue down the road until all the 'studies are done'. They could simply delay doing anything by calling new first minister's meetings to discuss the issue and come up with 'creative solutions'. They could accept the ruling but introduce legislation making it possible for private care but put in additional taxes and regulations to leave it all but unprofitable to actually practice privately. They could also invoke the "notwithstanding clause", although that seems unlikely.
With liberals, socialists and unions basically calling the shots in most areas of our governance, the one thing I don't expect is for them to accept this ruling quietly and allow two tier to grow in any sort of a capitalistic sense.
