Tomorrow's Today in History has events for CHUM and CKLW. Which got me to thinking: I want to verify some things I think I know about CHUM, CKLW and CFRB.
If you know anything to contradict the following statements, I would really like to know about it:
(1) CKLW-800 Windsor had the largest audience of any Canadian radio station ever (in its glory days, with top personalities and a Drake Top 40 format, centred several years either side of 1970).
(2) CFRB-1010 Toronto had the largest Canadian audience of any radio station ever (in its glory days, in the 1960s and early 1970s).
(3) CHUM-1050 Toronto had the largest Canadian audience of any music-based station ever (in its glory days, in the 1960s and early 1970s).
