My Opinion:
Canada loves their system, its wonderful.
Currently a giant percentage (I'm not sure, but I know someone is pushing for 90% goes to the care, and the health care lobby is trying to stap it like mad) of what you pay doesn't go to your care, it goes to the health care companies. My family pays 20,00 in health care a year. Thats a family of five. If we went to the government system of course taxes would increase. But by $20,000? Of course not. As the government doesn't have any big executives or a company to maintain then more will go into the actual care. Thus we would save money by going to a socialized system. We already have a socialised system; ask any docter, any at all. If you have insurance, you pay for those who don't and declare bankruptcy. My dad, as a doctor, has never received a payment from someone in cash. Only from the insurance agency. Thus your money is paying or others healthcare.

If the government pays for it, your taxes will increase (but not by much) , you wont pay anything for health care, and the treatment will not change much. Sure hospitals will be less comforting, but who gives a forget. Your in there for like 3 days half the time, then you go home. Also less pampering, more lets get you healthy and out of here, like it should be. ON the plus side no more checking insurance before they fraking give you Tylenols.
