I'm a Canadian American, who studies the US health insurance market for a living... privatization would be fucking disastrous.
If you want an idea, just look at paid parking near hospitals and how fucking expensive those lots are... and you still can't get a fucking spot.
The only way to reduce wait times is to increase supply or reduce demand... wait times will only significantly decrease if healthcare is unaffordable to the majority of Canadians or if we better fund public healthcare to attract more doctors.
