In 1944, the CBC Dominion Network was formed. The existing network was then named the Trans-Canada Network.
In 1949, CKNW New Westminster moved from 1230 to 1320 KHz and increased power to 1000 watts. The station had been broadcasting 24 hours a day, a first in British Columbia, since 1947.
In 1967, CKFH Toronto went full-time Top 40, having run the format evenings since Autumn. The FH in the call letters stood for owner Foster Hewitt, legendary play-by-play announcer for the Toronto Maple Leafs. The station signed on February 21, 1951, running 24 hours a day, despite only having 250 watts on Graveyard Frequency 1400 KHz. CKFH moved to 1430 KHz with 5000 watts in July 29, 1959, in a three way switch, that saw CHEX Peterborough move to 980 KHz, and CKPT Peterborough to be licensed to 1420 KHz. During CKFH's Top 40 years, the station gave CHUM a run for its money, but switched to Country in 1975. With a power increase in 1967, to 10,000 watts full-time, CKFH could be heard in Vancouver after midnight most winter Sunday nights, when they played a mix of album cuts. Foster Hewitt sold the station in 1980 because of failing health and 1978's loss of the Maple Leafs broadcast rights to CKO-FM. The Leafs were the station's major money maker.
