It's unlikely you'd see 8 ACCS as I believe they only take QL5 qual personnel.
To get a fully rounded radar experience (PAR, ILS, ASR, SSR), you'd want a full AF base - which limits you to Comox, Cold Lake, Moose Jaw (not sure if they have ILS or not, and whether they're maintained by contractors), Trenton, or Bagotville. Anywhere else is likely only to have limited radar equipment.
While you're in EMAA, you should see a "My Career" link or something like that. It will take you to the Career Manager's webpage, which will list all positions for ATIS, as well as position opening dates. You should be able to tell from there where they have Pte techs employed.
By the way, Canadian Coastal Radar (CCR) is maintained by the Air Reserve.
