Can I get a canadian bank loan with bad credit for med school?

Hi Everyone,

I'm from Ontario, Canada.
I graduate university in 2 years for my undergrad degree.
I underwent some financial difficulty this year and my credit was damaged, now it is considered poor according to Equifax.

I plan to spend the next two years re-pairing it, and hoping that by the time I apply to Saba University for med school, that when I get accepted, a bank will actually consider me with a co-signer. My father and mother are willing to co-sign since they fully support my dream of becoming a doctor.
I've read that OSAP doesn't cover all the fees of an international med school?

Any tips?

Thanks !
