Not sure if anyone has been in this situation before, but if I were to get a 1 year deferral for a US medical school to complete my masters, are the binding policies of a deferral only concern US medical schools? I wanted to apply to US schools a year earlier so I don't have to take my MCAT again (expiring) and for early assurance, given I get the acceptance and deferral of course. Then I will apply to Canadian schools during the deferred year, and if I get an offer I will accept the Canadian one. If not I continue with my deferred acceptance offer. Hope that makes sense.
