ED : Binding
EA : Non-Binding
REA : Non-Binding, but you can only apply to that uni (+ publics)
So you can’t ED to Columbia + Duke + JHU + Amherst + Northwestern. You can’t apply to Harvard EA either (unless you’re planning on ONLY applying there early + public uni’s).
I think that your chances of admissions at the University of Toronto are very good with or without a reference from this professor. However, getting accepted is not worth much unless you can afford it.
Having a good reference from a U of Toronto professor who knows you well and who you have worked with would be a significant positive. The Lester B Pearson scholarship would still be a reach.
Be aware that „need blind“ often only applies to domestic applicants!
Given your impressive extras, your classical dance training, and your interesting CV, you might want to also consider Barnard College at Columbia Univ. which is always seeking out exceptional females.
Again, as an international student finances would be an challenge!
Why? Seriously, you appear to be a very very strong student: why would your profs not say 'this is an exceptional student"?
“I got paralysis”
From a physical cause or psychological? I understand why it shouldn’t matter but you can bet that an AO will view a drop in academic performance from one differently than the other.
Those schools are need-blind for international students too, but AO’s can typically tell if you require aid or not based on your zip/area code + type of school/etc…
