Where we are in southern Ontario, we have OHIP which pays for your doctors visits as well as your hospitals I tend to get sick often needing med therefore we have insurance which cost me $1,500.00 per year. My sister who has been single all her life is in Quebec and she can only get a welfare every month of $600.00 per month. She chooses to live in a two room (bathroom and then tiny living/bedroom,kitchen) She has no medical plan.
As far as a retirement plan, I've never heard of anything of the sorts. You work, you invest all on your own. We will get an old age pay out at sixty-five but it's not much.
