CNRO was launched in 1924 as a Canadian National Railway radio network station. It operated on AM 690 and later switched to 600. In 1933, the station was taken over by the CBC's predecessor, the Canadian Radio Broadcasting Commission and became CRCO on 880 kHz AM. The call sign changed to CBO in 1937 when ownership was transferred to the CBC. Later frequency changes to 910 in 1941 and to 920 in 1977 (the latter accompanied by a power boost to 50,000 watts) were followed by a move from the AM to the FM band at 91.5 in 1991. The call sign of the existing CBO-FM station on 103.3 (part of the CBC Stereo network) was then changed to CBOQ-FM. From 1924, the station's studio's were located on the sixth floor of the Chateau Laurier Hotel in downtown Ottawa, a legacy of its origins with the Canadian National Railway which had also owned the hotel. In 2004, the station left the Chateau Laurier, ending the oldest operating radio studios in Canada, and moved to the new CBC Ottawa Broadcast Centre on Sparks Street as part of a consolidation of various Ottawa CBC facilities.
The station's local programs are Ottawa Morning in the mornings and All in a Day in the afternoon. However, most of the relay transmitters air the Toronto-originated Ontario Morning in place of Ottawa Morning. Unlike most CBC Radio One stations, which air provincewide morning programs on Saturdays and Sundays, the station also produces its own Saturday morning show, In Town and Out.
In addition, CBO produces Bandwidth, a music show which airs on all CBC Radio One stations in Ontario outside of Toronto, the regional noon news and talk program Ontario Today, which airs on all CBC Radio One stations in Ontario including Toronto, and the national network program, The House.
