Hi Ivanc,
This is the first time I am commenting in this section since I am a newcomer! I have also applied for a position at some universities in Canada and understand how it feels to get rejected when you are almost sure you will get in. As an international applicant, I have had the same experience as yours recently and I want to tell you not to doubt your abilities and strengths. Stay strong and never lose your hope. I hope you will get accepted at the other universities you have applied for.
Best wishes
