As a benefactor of this "free and universal healthcare" I can give you only my perspective and compare to what I know of Americas.
First, quality is far better in the U.S. I'm talking about sheer competence and skillset of doctors. In fact, we lose many of our top talent to the U.S, so, even on that standard alone, we are losing. I've been on many U.S forums and heard about the successes of their healthcare, I've watched many U.S health practitioners on youtube and elsewhere. You have more variety and competence in your system.
Universality is true in theory, but, in a covert system of centralized power, there is always someone who can pull the strings to deny your pursuits of healthcare. Government run is just that.
Have bad experiences in our system? Who are you going to complain to for accountability? Employees are unionized and overworked. Good luck with that.
We also have what is referred to as "Hallway Healthcare". Since we lack beds, doctors and nurses even though funding from our taxes is allocated far more to healthcare than any other issue, at least on the provincial level. So, we aren't as expensive as the U.S system but still have mismanagement or lack of resources to deal with a small population. People are being misdiagnosed, dying in hallways, on floors, or, without even being able to see a doctor. It's cruel, immoral and an insult to God. It's also not uncommon in our system.
We could certainly use A.I in our system, and we could use more efficiencies as well.
I'm more of a fan of a hybrid system as I believe a private/public system works best. All systems need full transparency of costs though and those providers need to be held to account in terms of profit margins.
You would expect slightly slower care in the public, but not enough for one to say "I have a far higher chance of dying in the public system over the private". The private system can support the public while offloading resources from the public system.
I am willing to bet that longterm, Canada won't be able to sustain a purely public model. We are already seeing the expansion of private services which years ago weren't even allowed. The wealthy will always receive better treatment, that's life. It can benefit everyone if it creates less wait times and ensures more beds are available in the public system.
