The transmitter building and studios was located on St. Jean Boscoe Street, near Cite Universitaire.

The tower contract had been let to Cobra Industries Inc. and the total estimated cost of TV station and building was CA$500,000.

The station started broadcasting an all-French service on March 17, 1957, when Télévision de Québec launched CKMI-TV.

When Radio-Canada opened CBVT on September 7, 1964, CFCM joined the loose association of independent stations formed by Montreal's CFTM-TV and Chicoutimi's CJPM-TV a year earlier.

Eventually, Famous Players reduced its shares to 20% by 1971, allowing Télévision de Québec to keep CKMI and CFCM.

In February 2018, the CRTC approved relocating the transmitter from its former studios on Myrand Street in Sainte-Foy to Édifice Marie-Guyart.
