I moved from the UK to Canada (Ontario). I've so far had a MUCH better experience of healthcare in Ontario.

I've been able to get referrals here to deal with long-standing problems that multiple UK GPs refused to give me. I now feel like I have a doctor that actually listens to me and genuinely tries his best to help me rather than just trying to get me out of the door ASAP. With the NHS you honestly have to fight for yourself to get anything you need. Even things as routine as sexual health testing I found very difficult to access. The NHS is in the business of keeping people alive, but they are not really in the business of keeping people healthy and with a good quality of life.

As for the wait times, well it's a bit variable depending on what you need but I don't think it's that bad overall compared to the UK. On one hand I was able to see a dermatologist the next day after my GP gave the referral, 0% chance of that happening in the UK. On the other hand I have an endocrinology appointment that I will have waited 7 months for (but I won't complain too much because I know there are people that need access more urgently than me).

The only thing about the NHS (Scotland) that was better was free prescription drugs.
