SATCOs are of the ATC variety, whereas the G3/FAC jobs can go to either. We split Maj/Capt positions in Edmonton, Pet, Valcartier, Gagetown with the pilots. The 8ACCS position is ATC, I believe. However (and someone may correct me), I believe the permanent AEC manning at 8ACCS is minimal - they draw qualified controllers, both IFR and VFR, from other bases when they have a tasking/exercise to go to. I believe there is a familiarization course with their equipment to qualify IFR or VFR controllers for 8ACCS ops.
CFAWC positions would be staff jobs, and thus open to both sides of the occupation.
