History
The station first signed on in 2004. It had a smooth jazz format. From December 2004 until August 2012, it called itself Couleur Jazz before being re-branded as Planète Jazz 91,9in the summer of 2008. On January 13, 2012, RNC Media applied to the Canadian Radio-television and Telecommunications Commission to amend its licence conditions to allow 50% of its programming to be spoken-word and talk programming, with the remainder being its existing smooth jazz format as well as blues and additional special interest music genres. Its application hinted that the station would take a direction more towards its Quebec Citysister station, CHOI-FM. On August 20, 2012 at 5:30AM, CKLX-FM flipped to the new CHOI Radio X format, sharing the branding with its sister station. The station primarily aired spoken-word talk radio programming, but aired music programming during certain dayparts to remain in compliance with its license at the time. These included blocks of jazz programming on evening and weekend mornings, and rock music programming on weekends under the name La Garage. The hybrid format remained in effect pending CRTC approval to allow CKLX-FM to switch to a mainly spoken-word format. The station's first effort to gain approval was denied by the CRTC on March 14, 2013. On April 8, 2014, the CRTC approved CKLX's request to discard its music requirements as part of its license renewal, in exchange for a requirement to carry a minimum of 50% spoken word and talk programming. While CKLX's new license took effect on September 1, 2014, the format change went into effect immediately. On September 9, 2014, the station was rebranded as Radio 9. A new on-air lineup was adopted, including Louis Lemieux, previously from Ici RDI. However, despite the changes, the station's ratings remained lackluster, due to continuous competition from the region's leading francophone talk station, 98.5 CHMP-FM. As a result, the station dismissed four of its on-air hosts, including Lemieux, in June 2015. At that time, CKLX announced that it would flip to an all-sports format. However, CKLX-FM continued to face competition from CHMP, as that station had the rights to most of Montreal's professional sports teams. CKLX adopted its new format and branding, 91.9 Sport, on August 31, 2015. Its weekday lineup initially consisted of sports talk programs throughout the day, followed by condensed highlight programs during the nighttime hours. Les légendes du rock continues to air on weekends. Several personalities from CKAC's previous sports talk era joined the station to host programs on the new lineup, including Michel Langevin, and Jean-Charles Lajoie. In August 2016, RNC Media announced the addition of new live programs, including the weeknight Sports Extra with Meeker Guerrier, and weekend evening Le 5 @ 7. Numeris ratings indicated that the new sports talk format had achieved the station's highest ratings in five years, with a 2.4% share. On August 28, 2018, RNC Media announced the sale of CKLX and CHOI to Leclerc Communication, owner of Quebec City's CJEC-FM and CFEL-FM. At first, the cost was not made public, but was later revealed to be $19 million. Citing a lack of revenue from the sports format, Leclerc filed a request with the CRTC to change CKLX's licensing to allow a music format, so that it could switch to a modern adult contemporary format similar to CJEC. The CRTC approved the deal, under the condition that Leclerc divest one of its stations in Quebec City. However, as Leclerc refused to agree to this condition, the company called off the purchase.
