Students pay taxes too btw. Personally, I paid taxes as a student, and a lot more as a temporary worker afterwards. And third, I mentioned a very specific class of PRs that I think deserve citizenship less than us.
I don't know what OHIP is. I live in Quebec and temporary residents do not have access to provincial healthcare. Also, we don't have access to a family doctor. Both provincial and federal banks do not give loans (for students who have very low income, low-interest loans are certainly a benefit) or credit margins to temporary residents. They also do not have access to a savings account (the one free of taxes). International students are also not allowed to apply for provincial or federal scholarships (a big disadvantage for students who want to pursue an academic career later). Should I go on? You speak of your own experience, but I'm talking about the conditions of many temporary residents. Big picture, you know.
