I've been reading this forum quite a bit since my partner was applying. So first of all, I want to thank everyone for all the great advice and tips! And second, don't worry my partner is in the same boat but she got accepted into the UofT MSW program. I think most people applying have the marks and enough experience (volunteer & placement) so your references and letter of intent are what separates you. As long as those are strong, you have a good shot.
