Here's a list of BC radio stations from a list in the Radio Service Bulletin of the U.S. Commerce Department of June 30, 1927.
Addresses in Burnaby were rejigged years ago, probably to match blocks in the city of Vancouver (numbers got larger as you went north, not south). 2243 Royal Oak between Victory and Beresford, just south of the interurban tracks. It was a house owned by a real estate agent.
The station in Mission moved to Chilliwack and became CHWK.
1006 Granville was the Belmont Hotel (at the corner with Nelson). I can't find that the station used CKWX any earlier than July 31, 1927.
The Presbyterian station wasn't on the air long; there's a post about it on this site.
