Albertan here. A couple of years back my brother and my dad both died of cancer (an unrelated coincidence) and I had the same experience - there was never a moment of stress about money. There also never felt like there were any untoward delays; when a situation was urgent we were able to jump straight to the surgery/MRI/whatever. There were a few times where we had to wait a few weeks for an appointment, but those were always the low-priority or followup things.
I know a lot of people think of Alberta as "North Texas" and imagine it's an American-style hellscape, but even if it might be a little below the general Canadian standards on some things it's nowhere near. It's important to be aware of the baselines that things are measured relative to.
