My guess is that the new hires will be based in YYZ or YUL as those are the most junior bases by far, YVR and YYC being the most senior. As for passes, there is a six month waiting period before you qualify for them, then you,your spouse and parents are entitled to unlimited standby travel, (not sure about dependants since I don't have any, at least none that I know of!!! LOL) You are also given 10 buddy passes per year that you can allocate to whomever you want, the catch being that you must travel with them. There are a few other little things but that about covers that basics. Hope it helps.
