In 1973, the CRTC approved the CBC's application to change the frequency of CBGR (later CBSI-23) Port-Menier, Quebec from 1420 kHz to 1130 kHz. In 1975, the CRTC approved the CBC's application to change the frequency of CBGL (later CBSI-13) Mingan, Quebec from 1290 kHz to 740 kHz and was later deleted in 1999. In 1986, the CBC received CRTC approval to switch frequencies on a number of CBSI low-power AM rebroadcasters in Quebec. CBSI-FM-2 previously broadcast as
CFKL, a local station owned by Hollinger-Ungava Transport Ltd. that operated at 1230 kHz. It is not known when the station began broadcasting, nor when it became a rebroadcaster of Radio-Canada, which acquired the station in 1965. By 1986, it was known as
CBSI-2 (it would become
CBSI-FM-2 upon conversion to 91.1 FM on July 15, 1994). On September 1, 2017, the CBC applied to convert
CBSI-5 1100 kHz to 99.9 MHz. On February 7, 2018, the CBC received approval from the CRTC to move CBSI-5 to 99.9 FM. On April 19, 2018, the CBC applied to convert
CBSI-8 1550 to 99.9 MHz. This was approved on September 6, 2018. On November 23, 2021, the CBC submitted an application to convert
CBSI-14 1350 to 105.9 MHz. The CRTC approved the CBC's application on February 2, 2022. On April 10, 2025, the CBC submitted an application to convert
CBSI-23 Port-Menier, Quebec from 1130 kHz to 99.9 MHz. CBSI-23 is currently the last low-power AM transmitters rebroadcasting CBSI-FM Sept-Îles and possibly one of the last remaining low-power CBC AM transmitters in Quebec. The CRTC approved the CBC's application to convert CBSI-23 Port-Menier from the AM band to the FM band on June 13, 2025. ==References==
