It is available on all Mexican cable and satellite systems, as well as over-the-air in Mexico City on digital television station XHHCU-TDT channel 45.

It has studio facilities in both the Chamber of Deputies and the Senate, and it is governed by a bicameral commission (Spanish: Comisión Bicameral del Canal de Television del Congreso de la Unión).

At the beginning of the LVIII Legislature of the Mexican Congress, the Bicameral Commission worked to achieve a milestone for the channel: the Comisión Federal de Telecomunicaciones, then the television regulator in the country, required all cable systems to carry it.

In 2013, the channel's director general, Leticia Salas Torres, stated that she wishes to expand Canal del Congreso's over-the-air reach outside Mexico City.

The SPR transmitters that carry Canal del Congreso use PSIP to display it on television receivers as channel 45.1.
