The station's studios are located on Jean-Perrin Street, along Autoroutes 40/73 in Les Rivières, and its transmitter is located at Place de la Cité in Sainte-Foy.
CHMG-DT is branded on air as Télé-Mag, which is a portmanteau of "television" and "magazine".
In August 2003, the Canadian Radio-television and Telecommunications Commission (CRTC) granted Télé-Mag a low-power terrestrial broadcast licence on channel 9, under the calls CHMG-TV.
[2] The station began broadcasting in high-definition via cable television in December 2010.
As CHMG-TV's transmitter is low power, it was not subject to the required analogue television shutdown and digital conversion, which took place on August 31, 2011.
