I'm a student that only has a visa debit card and as far as I know I have no credit bad or good what so ever. I have a SIN card but no drivers license. I am also 18. I also plan on getting only a small tab.
It's possible you might be able to get one on the spending limit program, but you will need some form of government photo ID if you don't have a drivers license. With no ID at all prepaid is your only option.
