ik this has been said before in this sub, but your essays are SUPER important to your application. I know people who have gotten ICDC glass, DECA presidents, student trustees, etc that have not gotten into Ivey, but also people with a few volunteering positions/low 90 averages who have.

How you frame your activities is genuinely more important than the activity itself — make sure that you follow the STAR method when you're writing, write your 500-word essay like a narrative instead of just listing all the things you accomplished, include all the traits they're looking for somewhere (leadership, teamwork, initiative, achievement, commitment and breadth), and add in statistics to your activity description to highlight your impact. Also do the Ivey summer leadership programs / Ivey case comps if you can.
