My father heard that by doing Volunteer work, that doesn't pay me, apparently supposed to affect my OSAP. Basically, I can apparently use the hours spent on volunteer work to make OSAP forgive some of the money I loaned. Is that true? Where can I find more information?

Im pretty sure that this is false. This was probably info from last year during the pan am games where people who volunteered received an extra 6 months added to their grace period. However the best place for more info is the student financial aid office!
