That last point you make is interesting. I would suggest that there's a general dialogue out there that students are not good at repaying their debt, that they tend to default more than average Canadians, that they're not good borrowers.
Getting back to your requests, you talked about increasing the loan limit. I'm surprised that there wasn't something in your brief that talked more about the grant portion. If we're trending towards higher debts and students are leaving it, we know that's an encumbrance upon the general economy. They tend to buy fewer things and tend to make career choices that are not optimal, in order to service the debt.
Why would you ask for more debt rather than seek more grants?
