Gordon Avenue in Verdun. The new studios are located at Place Bonaventure in downtown Montreal. On April 30, 2010, Cogeco announced it would purchase Corus Quebec's radio stations, including CKOI-FM, for $80 million. On December 17, 2010, the CRTC approved the sale of most of Corus's radio stations in Quebec, including CKOI-FM, to Cogeco. On November 24, 2011, the CRTC determined that CKOI-FM had abusively used musical montages of English-language songs in order to circumvent French-language music quotas, and imposed a condition of licence on the station limiting the broadcasting of montages to 10 percent of the broadcast week. In 2016, Cogeco applied to the CRTC for permission to move the transmission site to Mount Royal, as space had become available there after the digital TV transition. Moreover, the move would allow Cogeco to co-locate all its Montreal FM stations, and the superior location would require lower power to achieve the same reception range. The transmitter was moved in late 2018. Effective radiated power is now limited to 148,000 watts, still much higher than the usual maximum. Shortwave relay For a period in the 1990s, CKOI-FM was simulcast over shortwave relay station CFCX on 6095 kHz, which had previously relayed CKOI's then-sister station CINW. In 1999, the transmitter was taken out of service due to its age and was not repaired or replaced, bringing shortwave service to an end. Personalities Throughout the 2000s, the station has been known especially for pranks by the Masked Avengers, a duo composed of Marc-Antoine Audette and Sebastien Trudel, against internationally-known personalities such as Jacques Chirac, Britney Spears, Sarah Palin and George W. Bush. The duo appeared first on a weekend morning show Les Justiciers Masqués, and later on a daily afternoon show Les Cerveaux de l'info, along with co-host Richard Z. Sirois. Comedian Pierre Brassard, also known for prank phone calls, was also previously associated with the station. CKOI-FM lost its longtime morning host Normand Brathwaite on March 17, 2006, following a conflict with former co-host Jean-René Dufort. Dufort became the station's morning host until June 22, 2007. Braithwaite joined CITE-FM in August 2011. One of the peak of daily audience is the record-setting program ("the six at six"), the top six hits at that point in time, broadcast daily at 6PM.
