I recently emailed the grad department about updating my academic transcript. This is what they replied:
"Firstly, the MEng program has limited space and is given priority to domestic students. I would advise switching your application to the MASc program, unless you have already secured a supervisor who is wishing to accept you into the MEng program.
You should be able to update your documentation through your application. If you have any difficulty updating your application, please contact the Graduate Admissions and Records office."
So, looks like an unofficial rejection letter to me. Also, I never knew securing a supervisor for MEng was important (if not compulsory).
