- For the history of the 570 AM frequency in Kitchener prior to 1993 (and its predecessors dating back to 1929), see CHYM-FM.
In 1965, the stations were acquired by Great Lakes Broadcasting, a consortium that included Maclean-Hunter. Both stations changed their callsigns to CHYM that year. Among the first disc jockeys on CHYM (AM) were Gene Scott, Vic Thomas, Sandy Hoyt, Keith Sterling, and Larry Shannon.
Distinct programming was launched on CHYM-FM for the first time in 1968. In 1972, the FM outlet's callsign was changed again, to the current CKGL.
In 1982, Maclean-Hunter took over full ownership of the stations.
The CHYM and CKGL intellectual units (call signs, branding, and programming, but not the licences themselves) swapped frequencies in 1992, with CKGL moving to the AM band. (CRTC approval was required, but only as a format swap between the existing stations at 570 and 96.7, not a formal exchange of frequencies.) The stations became part of Rogers Communications in 1994 when that company acquired Maclean-Hunter.
When CHYM and CKGL swapped frequencies, the CKGL country music format was moved to AM with CKGL. In 1997, this successful format was changed to news talk radio.
In late 2005, CKGL adopted the popular all-news format for the morning and afternoon drive time slots.
In 2007, 570 News won the RTNDA Edward R. Murrow Award for "Best Newscast". The winning newscast aired Friday October 6, 2006 at 7 AM and highlighted RIM co-CEO Jim Balsillie's intent to buy the Pittsburgh Penguins. 570 News had a reporter live in Pittsburgh when Balsillie made the announcement.
Unlike the Rogers all-news stations in major markets like Toronto (680 News) or Vancouver (News 1130), CKGL only carries continuous news programming during morning and supper hour drive on weekdays (5:00 to 9:00 a.m. and 6:00 to 7:00 p.m.) and throughout the morning on weekends (6:00 to 11:00 a.m. Saturday, 6:00 a.m. to noon Sunday). Local news updates air every half hour during the daytime talk shows, but the station relies on hourly Canadian Press newscasts overnight.
Talk Shows run weekdays (9:00 am to 6:00 pm). The evening and weekend afternoon hours are largely filled with sports programming, including Kitchener Rangers and Toronto Maple Leafs hockey, Toronto Blue Jays baseball and Buffalo Bills football.
