I've applied for the 7-year MD program in collaboration with Waterloo University and submitted my initial documents that were available. I'm unable to provide my passport and English proficiency test results until I have some indication of acceptance, like a conditional letter, as I'm managing this application independently and cannot afford the expensive test without some hope of admission. I emailed the assigned admissions officer but haven't received a response. Does anyone know how to best contact them, or how long it typically takes to get a reply?
