I think you have a pretty competitive application!! I agree with slpdreamer, I'm pretty sure grades are weighted heavily at U of T. My supervisor graduated from U of T and when she applied, she had no research experience, the bare minimum for clinical experiences but had high grades + great references. I do think you should apply to UWO as well however, because from what people have been saying in this thread, they seem to have a more lenient preference towards clinical exp. and yours sounds diverse and fitting for their program. Good luck!!
