CHAU-DT is a French language television station affiliated with TVA in Carleton-sur-Mer, Quebec, Canada. It broadcasts an analogue signal on VHF channel 5 from a transmitter near Rue de la Montagne in Carleton-sur-Mer.
The original owner of CHAU was Dr. Charles Houde of La Télévision de la Baie des Chaleurs, who put the station on the air for the first time on October 17, 1959. Initially, like all other Quebec private TV stations, CHAU was a dual CBC/SRC affiliate airing both English and French shows. For CHAU, the ratio of English to French programs was 7:13. The station entered Radio-Canada's microwave network on March 24, 1960, and became an all-French station in 1968 when Montreal's CBMT opened a rebroadcaster in Carleton. In 1978, it became one of the last Canadian stations to air local programming in colour.
In 1979, the Canadian Radio-television and Telecommunications Commission (CRTC) gave CHAU a mandate to extend TVA service to northern New Brunswick and the Gaspé as part of an effort to improve French-language television service in those areas. Accordingly, around 1980, CHAU began carrying TVA programming in off-hours. It became an exclusive TVA affiliate on December 18, 1983, when Radio-Canada opened a rebroadcaster of CBGAT in the Carleton area.
CHAU-DT holds the distinction of owning the largest rebroadcaster network of any privately owned station in Quebec. Its rebroadcaster network blankets the Gaspé, and it also operates three rebroadcasters in New Brunswick. The station's main signal also covers most of northern New Brunswick—its city grade signal covers Campbellton, while its grade B signal reaches Bathurst. It also operates a bureau in Bathurst. CIMT also operates a rebroadcaster in Edmundston, and between them the two stations provide TVA service to the entire province.
CHAU-DT was approved by the CRTC for and had plans for converting its transmitters to digital by the August 31, 2011, digital transition deadline, though none of its transmitters are subject to this deadline; neither the Gaspésie region nor the Campbellton area are designated as a mandatory market for digital television conversion. CHAU-DT converted all of its transmitters to digital in November 2011.

CHAU-DT-5 was approved by the CRTC on April 8, 2013 to relocate its broadcasting frequency from channel 13 to channel 11; the station's owners cited interference from CBC Television station CBCT-DT in Charlottetown, Prince Edward Island, which also broadcasts on channel 13, as the reason.
