I sent my application in the beginning of November last year. And they did not get the official TOEFL score at first. I had to ask ETS to re-send the score to them. They always lost some of your files. I got my offer at about Jan. 10th. Remember, keep asking them about your application after you send them your files. I don't know why they gave me an offer like that. Maybe because the date on which they issued the offer. At that time, the winter term has begun. If there are no course available in the summer term, I can only start from the fall term.
You mentioned the secretary in your words, is it Marie Rainville? I think I'd better send her an e-mail.
Good luck!
BTW, there is Engineering Management Program in Univercity of Alberta. They only require 24 credits for Master's degree and U of A is better than U of O.
