History.
The station was launched in 1943
, the station moved to 740 kHz; its former channel, now 860 kHz, went to CFRB (which would relocate to 1010 kHz in 1947), while the 840 kHz clear channel was relocated to Louisville, Kentucky, where it was taken by WHAS. (See Canadian allocations changes under NARBA.)
Between 1938 and 1943, CBL had a rebroadcaster, CBY, to supplement coverage in Toronto. CBY broadcast on 960 kHz, switching to 1420 in 1939 and then to 1010 in 1941
