Again, take this with a grain of salt (Doc Strange will have a better answer for this question because he's experienced more admissions-wise).. but it felt to me like they are looking for the kind of student that isn't strictly academic. They seemed to place a big emphasis on volunteering in one's community specifically. They have enough applicants that numbers alone won't really do it. You don't need stellar ECs but definitely be ready to expand on your non-academic commitments in the interview. I don't think we even spoke about academics..
I'd also point out that they pride themselves on producing practitioners. That's not to say that you shouldn't apply if you plan to do research/not practice, but I think they do prefer for people that ultimately want to practice.
Just my impressions,
@Doctor Strange can probably elaborate better.
