Montreal's only French-language all-sports radio station will vanish as of 4:30am Tuesday, just in time for the morning rush hour. That is when Cogeco's CKAC-AM "Sports" (730) becomes "Radio Circulation," Montreal's only all-traffic and weather radio station in either language. The new format, which will receive $1.5 million in government funding, will also come with another cost. Several of Cogeco's competitors, including Astral Media, have filed an opposition to the government funding plan and format change. The CRTC will hold a public hearing on the matter October 17, says the Montreal Gazette. In order to accommodate the all-traffic & weather format, Cogeco will move the Canadian Football League Montreal Alouettes and the NHL's Montreal Canadians broadcasts to sister-station CHMP-FM (98.5), where some of the CKAC talk hosts and on-air staff will also find a new home. Cogeco has withdrawn its earlier application to create a French all-traffic station at 690, but will continue with its plans for an English-language traffic outlet at 940. The Canada Board of Radio-Info.com says the 730 frequency has been featuring just adult contemporary music since Friday's blowup of sports CKAC. THe new traffic-and-weather format should debut Tuesday (9/6) at 4:30am. See what the Canada Board is talking about, here.
