Hey, I received conditional acceptance to UBC-O for September 2018 as well. I heard back in December though, so strange. I am still waiting to hear back from Vancouver as well. I just send an email to the field education coordinator if there is any chance i could do a practicum back in my home community (Vancouver).
My acceptance to UBC-O is still conditional as they are waiting for my final transcripts and criminal record check to go through.
Did you accept the offer?
