History of CFTR
The station launched in 1962 on 1540 kHz as CHFI-AM, simulcasting the beautiful music of CHFI -FM, one of Canada's first FM radio stations. Since 1540 was a clear channel frequency assigned to stations in the United States, CHFI-AM was only authorized to broadcast during the daytime. In 1963, it sought to pay CHLO in St. Thomas, Ontario to move from 680 to another frequency to free up 680 for CHFI-AM's use. No deal was finalized, but by 1966, the stations reached an agreement to share 680 and CHFI-AM moved to twenty-four hour operation at that frequency. In 1971, it changed its call letters to CFTR, a tribute to Ted Rogers, Sr., radio pioneer and father of controlling shareholder Ted Rogers.
In 1972, it abandoned the simulcast of CHFI and adopted a Top 40 format for which it became legendary. For many years, it was the primary competition to Toronto's original Top 40 station, 1050 CHUM.
It adopted its present all-news format in 1993, becoming the first all-news radio station in Canada since the end of the former CKO network.
