to me procedure seems pretty easy, send an email with the reason to the program co-coordinator and a money order.
This is what I received in the email from program co-coordinator
If you need to defer your admission to the M. Eng. program to January, May or September 2014; you will need to send a letter requesting a deferral with the reason. An international money order or bank draft payable to University in the amount of $25 is needed.
If you have a friend at Concordia who is willing to bring a money order payable to University in the amount of $25 with your name printed on the money order; ask him/her to see me at EV 3.152. As soon as a I receive an e-mail from you requesting a deferral of admission to ... with the reason and the money order, I will start processing the deferral of admission.
OR
If you have a friend in Canada/USA who is willing to mail a money order payable to University in the amount of $25 with your name printed on the money order; ask him/her to mail it to me at the above-noted address. As soon as a I receive an e-mail from you requesting a deferral of admission to ... with the reason and the money order, I will start processing the deferral of admission.
so can you please explain now what do you mean by deferral procedure?
I am more interested to know what my friend has to do while purchasing a money order... kindly help..its urgent.
Here http://www.canadapost.ca/tools/pg/manual/PGmoneyord-e.asp, it is written that
Customers purchasing a Money Order are required to provide the Sender and Pay To type and Sender and Pay To names at the time of purchase.
So that means sender name is required.
