OP. What province are you in? Your province will provide your financial aid. If you’re in Ontario, OSAP should cover all your expenses plus a stipend. At some point your parent will have to file taxes though because OSAP will not accept the “not required” excuse.
If you’re in a different province, the situation may be a little different but you shouldn’t end up with a lot of loans at a Canadian university. Speak to your guidance counselor ASAP.
