CBC Television station in Ottawa

CBOT DT (channel 4) is a CBC Television station in Ottawa, Ontario, Canada, serving the National Capital Region. It is part of a twinstick with Ici Radio Canada Télé station CBOFT DT (channel 9). The two stations share studios at the CBC Ottawa Production Centre on Queen Street (across from the Confederation Line light rail station) in Downtown Ottawa, alongside the main corporate offices of the CBC; CBOT DT's transmitter is located on the Ryan Tower at Camp Fortune in Chelsea, Quebec, north of Gatineau.

CBOT went on the air for the first time on June 2, 1953 (broadcasting the coronation of the Queen of Canada, Elizabeth II), becoming the third television station in Canada. Before the launch of Télévision de Radio Canada station CBOFT, CBOT aired both English and French language programs. During the late 1970s into the early 1980s, CBOT was known as "CBC 4 Ottawa", and its newscasts were known as CBC 4 News. In 1980, CBOT's 6 p. m. newscast was anchored by Ab Douglas, and by Joe Spence at 11:27, following The National. During the mid 1980s, the station was known as "CBOT 4", now "CBC Ottawa".

CBOT DT presently broadcasts 10 hours, 40 minutes of locally produced newscasts each week (with two hours each weekday, a half hour on Saturdays and ten minutes on Sundays). CBOT airs local news programming in the form of a 90 minute newscast from 5 to 6:30 p. m. and a half hour newscast at 11 p. m. on weekdays. On weekends, the station airs a half hour 6 p. m. newscast on Saturdays and a ten minute summary airs on Sundays at 11 p. m.

On August 31, 2011, when Canadian television stations in CRTC designated mandatory markets transitioned from analogue to digital broadcasts, the station's digital signal remained on UHF channel 25, using virtual channel 4.

CBOT operated six analog television rebroadcasters in Eastern Ontario and included communities such as Pembroke. Due to federal funding reductions to the CBC, in April 2012, the CBC responded with substantial budget cuts, which included shutting down CBC's and Radio Canada's remaining analog transmitters on July 31, 2012. None of CBC's or Radio Canada's television rebroadcasters were converted to digital.
