The 1550 frequency was previously used by CBEF's English language sister station, but CBE converted to the FM band in 2013 (now CBEW-FM 97.5 MHz).

In the CBC's programming cuts announced on March 26, 2009, almost all of CBEF's local programming was slated for cancellation, meaning that the station would become effectively a rebroadcaster of CJBC except for a skeleton staff of two anchors to present local news updates during the day and report on breaking news.

[3] Matins sans frontières, a one-hour local morning program hosted by Charles Lévesque, was reinstated from September 7, 2010, and in May 2013 was expanded to two hours.

At the Canadian Radio-television and Telecommunications Commission (CRTC)'s license renewal for the CBC's services in 2013, the commission directed the network to maintain at least 15 hours per week of local programming on CBEF during the 2013-18 license term, due to the lack of other French-language radio services in Windsor.

Due to AM reception issues in downtown Windsor, CBEF was also approved by the CRTC to operate a 620-watt nested rebroadcaster in Windsor at 105.5 MHz, provided that does not interfere with stations at or near this frequency, such as WQQO in Toledo, Ohio or WWCK-FM in Flint, Michigan, both Top 40 stations owned by Cumulus Media.

In May 2012, the CBC filed paperwork with the CRTC, seeking permission to move CBEF to CBE's previous transmitter and frequency of 1550 AM at 10,000 watts.

The technical parameters for the move include a constant power of 1,886 watts and a height of 107.4 meters EHAAT on the same tower as CKCI-FM.

The station would also become short-spaced to WRVF in Toledo, Ohio, also on 101.5, as well as CKNX-FM in Wingham on 101.7 and CKOT-FM in Tillsonburg on 101.3 MHz.
