Yea those guys are helpful, especially starfish. You'll want to apply to OSAP through here,
Fill out the form quickly, I think you have a few days left to get your OSAP ready before September 5th. If you miss that date you may not get your OSAP funding by September 5th. Anyway, just make sure you honestly fill out the forms, there is a signature that allows them to contact some financial firms and dig up all kinds of information about you. So you will want to be honest to avoid trouble later. At the end of the you will need to print out I think 7 pages of forums, just sign them, I think like two or three of those pages will go to McMaster, the rest go to a Canada Post Office, you will be able to tell which ones are which in the instructions.
Hope that helps,
All the best.
