Your position is not that unique. In 2007 I was posted on IR to Petawawa from Gagetown, NB. In 2008, I deployed to Afghanistan, and was posted back here in 2009. While I was "away", I got next to squat support from the MFRC. If I were you, I wouldn't even talk to them. IMHO, they are incompetent.
As an illustration, during my tour, the Prime Minister came to Petawawa as part of an MFRC Christmas tree give away to spouses of those deployed. Even though my wife's info, including address, clearly stated that she was in New Brunswick, she still received an invite from those idiots to come for the event. My wife wasn't pleased, to say the least.
I don't know your complete situation, and that's fine, but if you can get a computer with internet access, preferably high speed, hook that up in your home. If that's not possible, contact the people at his current unit, the nearest unit, etc. Heck, there may even be people on this forum who could help.
