financial aid questions

<p>I have posted on here before about my interest in going to private school, and it is a possibility providing that I can get the money.
Is financial aid only available through the school? The school that I’m interested in attending covers max. 50% of tuition… so does that mean if I wanted any more financial assistance I would have to go through loans?
If so, what is the lowest interest loans available in Canada? Or where would you recommend I get a loan?
Also, would I be able to get a loan that I can re-pay in small payments, and then finishing paying when I’m in University (or done University)? That way I could pay it back on my own, instead of entirely relying on my parents to do so.
Thanks so much.</p>
