Will OSAP cover?

I’m 17 years old from Toronto and looking at studying at Guelph.

My parents want me to go away for school but don’t have the financial facilities to fully cover it, so they said they will cover tuition as long as I cover living expenses which I am extremely grateful for.

I work as a hockey referee but pretty much live pay check to pay check as I spend whatever I make on my car payment. I don’t have time on my hands to pick up another job between school, hockey and my refereeing, so I was wondering if OSAP would cover the whole thing and how it would work out.

If OSAP were to cover tuition and some of living, would I have to pay it off? Or would it be on my parents and I just give mt parents money for the living cost.

Any help or advice would be appreciated, thank you.
