1987
On July 10, the CRTC approved the applications by 149178 Canada Inc. for new French-language radio services in Rouyn-Noranda on the frequency 99.1 MHz with an effective radiated power of 1,000 watts, and in Val d'Or on the frequency 102.7 MHz with an ERP of 49,400 watts. Competing applications by Communications Nord-Média Inc. and by Normand Roy, representing a company to be incorporated, were denied. 149178 was owned equally by a corporation controlled by Yvon Larivière of Rouyn-Noranda and by Radiomutuel (1985) Limited. Larivière had more than 25 years' experience in broadcasting, almost twenty of which were acquired in the Abitibi-Témiscamingue region. Larivière stated that he intended to work at the new station on a full-time basis as President and General Manager. The stations would be operated in the Group IV dance music format with equal representation from categories 51 and 52 (pop and rock-softer and pop and rock-harder). The applicant emphasized that this was a new alternative for a major segment of the audience in the 12-to-34 age group, which was inadequately served at present and which constituted 53% of the total population in the central coverage area of the proposed stations.

1988
CJMV-FM was authorized to increase effective radiated power from 49,400 watts to 63,100 watts. The transmitter would be relocated to a site adjacent to the one authorized in 1987. The Commission noted in that decision that Cuivor (formerly 149178 Canada Inc.) had not yet completed its negotiations regarding access to and sharing of the antenna site at Lithium Mines with Radio Nord Inc., the owner of the transmitter site, and with the Canadian Broadcasting Corporation, a lessee of the site. Also, Communications Canada had concerns about the site chosen and stated that the proposal to locate a transmitter at Lithium Mines is "a special case acceptable under certain conditions" only. As the negotiations were unsuccessful, the licensee filed the present application to use a different antenna site in order to satisfy Communications Canada's requirements having negotiated an agreement with Cambior Inc., a mining company, and with the municipality of Lacorne.

CJMV-FM signed on the air on June 17.
