YEs you can attach TT or wire transfer reciept as fees payment proof.
And fees reciept delivery generally depends upon college working days, as in my case it took whole week, I have paid my fee on 8th Nov, 9th November there was a meeting at registrar of at sheridan, 10th & 11th was a holiday (weekends), On the 12th they accepted my fees and send me reciept which I recieved on 13th in India. So these can be circumstances.
