Hey again,
I would recommend going to the base in Ottawa, if you know any of the clerks there and try to talk to the chief clerk. Let them know you are getting in and that you would like to get to Ottawa for "Contact Training" after BMQ. I would do this only after you get accepted. Also, ask any questions you have and see how it goes. I did this in Greenwood and I was able to get back to Greenwood for contact training. My WO there was a valuable asset in getting me home, I think it helped because 1) he is a wonderful person willing to help anyone who needs help and, 2) because he had met me and taken the time to get to know me, I was a person with a background, not just a piece of paper to him and through him, the Career Manager. I also wrote a memo in BMQ to request Contact training and was told that my next training base would decide about sending me home. So, you may have to wait until you are done BMQ and get to Borden. In most cases the military would rather send you home, if close to a base, as then they don't need to pay rations and quarters and seperation for you, if you are married.
Good luck.
