History

CBOT went on the air for the first time on June 2, 1953, 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".
