Uh first of all a bank doesn't give you an OSAP loan... they give you private student loans.

You have to apply online for the OSAP (or go to the actual office and apply in person) at https://osap.gov.on.ca/eng/eng_osap_main.html
If you actually have an OSAP loan you can log on their with your SIN or OSAP number and check out your ballance (go to check status).

If this page doesn't look familiar you didn't get OSAP. period.
