I'm not sure if there are distance regulations, but I believe as long as you are living away from you spouse you count for it. (Correct me if I'm wrong.) On basic, even if you spouse lives in lets say Montreal, you are still living away from them, because you are living in quarters in Saint-Jean. I'm from Halifax myself, and I left my fiancee and daughter back home here when I did IAP and BOTP. I however did not qualify (or did, but did not receive) separation pay, because I was sent on temporary duty "TD" and I received a TD allowance instead. You cannot receive both TD and separation allowances. However, during your time in farnham, if on TD you are taken off and given field pay (I think then you get both field pay and sep. pay, but I cannot remember)
