CBSI-FM

Formerly established on December 12, 1976, as a rebroadcaster of Matane's CBGA, CBSI-FM was launched as a separate station in 1982. The station now has several rebroadcasters of its own throughout Quebec's Côte-Nord and in parts of Labrador.

The station's current local programs are Bonjour la côte, in the mornings from 6 a.m. to 9 a.m., and Boréale 138 in the afternoons, 3:30 p.m. to 6 p.m. CBSI-FM also co-produces D'Est en est, a pan-regional program produced in turn with CBGA-FM and CJBR-FM Rimouski, and heard afternoons during the summer months. On public holidays, its local programs are replaced with local shows airing provincewide produced by different outlets in turn (except Montreal and Quebec City). Its Saturday morning program, Samedi et rien d'autre, originates from CBF-FM Montreal.

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. ^[1]

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 ^[2] and was later deleted in 1999. ^[3]

In 1986, the CBC received CRTC approval to switch frequencies on a number of CBSI low-power AM rebroadcasters in Quebec.^[4]

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).^[5]

On September 1, 2017, the CBC applied to convert CBSI-5 1100 kHz to 99.9 MHz.^[6] On February 7, 2018, the CBC received approval from the CRTC to move CBSI-5 to 99.9 FM.^[7]

On April 19, 2018, the CBC applied to convert CBSI-8 1550 to 99.9 MHz.^[8] This was approved on September 6, 2018.^[9]

On November 23, 2021, the CBC submitted an application to convert CBSI-14 1350 to 105.9 MHz.^[10] The CRTC approved the CBC's application on February 2, 2022.^[11]

On April 10, 2025, the CBC submitted an application to convert CBSI-23 Port-Menier, Quebec from 1130 kHz to 99.9 MHz. ^[12] 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. ^[13]
