CBU is a Canadian non-commercial public radio station, in Vancouver, British Columbia.

CBU's newscasts and local shows are also heard on a chain of CBC stations around the Lower Mainland.

CBU's studios and offices are in the CBC Regional Broadcast Centre at 700 Hamilton Street in Downtown Vancouver.

[4] The station moved to 1130 in 1941 after the enactment of the North American Regional Broadcasting Agreement (NARBA).

The station began broadcasting at 50,000 watts, the highest power authorized by the Canadian Radio-television and Telecommunications Commission (CRTC), allowing it to be heard throughout the Metro Vancouver Regional District and around the British Columbia Coast.

In early 2008, the CRTC approved CBU's application for a new simulcast of its programming on the FM band.

The ability to increase the signal coverage area was made possible when CHEK-DT in Victoria moved from VHF TV channel 6 to 49, as part of the over-the-air digital television transition.

[7] In 1941, CBR established a shortwave relay for remote areas of British Columbia using the call sign CBRX and operating on a frequency of 6.16 MHz (in the 49m band) with a power of 150 watts.

[8] In 1965, the call sign changed to CKZU, recognizing that the ITU prefix CB was not assigned to Canada, but to Chile.

CBU also originates the lunch-hour show BC Today, hosted by Michelle Eliot and simulcast over CBUT-DT,[11] as well as the weekend programs North By Northwest, hosted by Margaret Gallagher, in the morning; and Hot Air on Saturday afternoons.
