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 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 August 31, 2011, when Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts,^[2] 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.^[3] None of CBC's or Radio-Canada's television rebroadcasters were converted to digital.
