Out here where they are headquartered, they use a mix of rented RCC repeaters and have numerous links into dispatch via simplex. A bunch of 939 MHz analog simplex have shown up here.
Look for them everywhere. As well they use their own channel simplex or duplex and have seen them locally carry two radios (Burnaby hospital) if there is a small RCC co there look at their stuff, they still have a bunch of LTR in use in lower mainland.
