Yes it is. I live in Ontario. The provincial (conservative) government literally froze the wages of nurses and other public sector workers in 2019 (see Bill 124), creating a massive exodus of nurses and a severe staff shortage. The provincial government doesn't have money to pay nurses, but it has enough money to build a useless highway (see Highway 413) that just so happens to go through land owned by the Premier's friends and business associates; or to give out millions in license plate rebates just before an election. That's also the same provincial government that intentionally didn't spend about $2.7 billion of federal COVID-19 relief funds (which could have, you know, funded healthcare).
Lastly, Canada's population isn't shrinking. It's growing, thanks to a sensible immigration policy (well, mostly sensible; not recognizing the credentials of healthcare professionals is pretty dumb).
Public healthcare is only difficult to find when your government's priority is to personally engorge on a gravy train powered by corruption. All of the issues facing the Ontario healthcare system are intentionally self-inflicted.
