Hey @mphzz
From what I've heard, and considering what you say your interests are, I think UBC's MPH might be better suited for you -- especially in terms of influencing and supporting your career aspirations overall. It also has a stronger focus on quantitative methodologies compared to UofT's Health Promotion MPH. But then again, you have see whether or not you're willing to go to BC to attend that program, as opposed to staying in Ontario.
Whatever you end up choosing, I wish you best of luck! I'm sure you'll achieve great things either way.
