OSAP can be a huge 500 pds Gorilla unless you tackle it early and with some discipline, otherwise it'll be around for a loooooong time and you'll be paying way more in interest that what the friggin' loan was.
Happily you can get breaks from the payments if you're between jobs by just paying the tax if you absolutely have to.
I don't recommend that at all, only if you really, really have to and truthly can't keep to the loan commitment because of lack of income.
As with any bad debt. kill it and kill it fast!
