The station [[signed on]] the air in 1936. The following year, it returned at 1420 kHz, as a signal booster for [[CBLA-FM|CRCT]]. The station's call sign was changed to CBY in 1938. In 1941, with the enactment of the [[North American Regional Broadcasting Agreement]] (NARBA), the station moved to 1010 kHz.

The station [[signed on]] the air in 1925. Its original [[call sign]] was CKNC and it broadcast on 840 kHz. It was owned by the Canadian National Carbon Company. In January 1927, the station moved to 690 kHz, returning to 840 kHz a month later. The station then moved to 580 in 1928, and to 1030 in 1931.

In 1933, the station was leased and then acquired by the [[Canadian Radio Broadcasting Commission]], the forerunner of the modern [[Canadian Broadcasting Corporation]]. It became CRCY, before leaving the airwaves in 1935. The following year, it returned at 1420 kHz, as a signal booster for [[CBLA-FM|CRCT]]. The station's call sign was changed to CBY in 1938. In 1941, with the enactment of the [[North American Regional Broadcasting Agreement]] (NARBA), the station moved to 1010 kHz.

A previous radio station with the call sign CJBC was owned and operated by the [[Jarvis Street Baptist Church]] from 1925 until 1933. That station went [[dark (broadcasting)|dark]] in 1933, after the government of Canada withdrew all religious broadcasting licenses.

The CJBC call letters were subsequently acquired by the Canadian Broadcasting Corporation to replace CBY. They were transferred on November 15, 1943.<ref>{{cite web |title=CJBC-AM, Toronto |url=http://www.broadcasting-history.ca/listing_and_histories/radio/cjbc-am-0 |website=broadcasting-history.ca |access-date=27 August 2019}}</ref> The call signs for all other CBC and Radio-Canada stations in major cities begin with "CB".
