Well, all I can tell you is that if you think it should have been 4/5 or 5/5, then it's worth a departmental review at the very least. There must be something in your med file that you think would lend itself to a rating of 4/5 or 5/5 - or is there something in your med file or dealing with doctors in general that would cause VAC to suspect that there's something other than military service to attribute your condition to? My advice would be to get in contact with BPA, and at the very least have a chat with one of their lawyers about it. You don't have to request a departmental review or VRAB appeal if you and the lawyer don't feel it's appropriate, but at least talk it over with one of their lawyers for a "goodness check".

- have a look at the descriptions for everything, and see if your condition has been properly assessed. The one-year wait for reassessment may be so that your condition has some time to stabilize, and they will re-evaluate once it is stable.
You should be able to call VAC at their normal toll-free number with your file number and request a case worker be assigned. While you're on the phone with them, explain your predicament with regard to finding a family doctor, and see if a VAC doctor can be assigned. Failing that, depending on which province you're in, there is usually somewhere you can go on the web to find out which doctors are accepting new patients.
