The CBC used to operate low-power rebroadcasters CBDD 560 Elsa and CBDX 970 Swift River; these rebroadcasters were deleted at the CBC's request by the CRTC on October 25, 2013.
The station has an extensive network of rebroadcasters throughout the province.
On May 16, 2008, CIAM has applied to the CRTC to add a transmitter at Buckland, Saskatchewan and another at Vanderhoof, British Columbia Also on July 15, 2008 the station applied to add more rebroadcasters to a number of communities in Alberta and received approval on November 6, 2008.
The following community-owned rebroadcasters are currently listed with the CRTC as rebroadcasting CKAC. Although traffic information for the Montreal area has little apparent relevance to these communities, no changes to this transmitter list (if any) following CKAC's 2011 format change have yet been published.
CJOB also has rebroadcasters in the following communities:
CITA has a number of rebroadcasters that serve communities in New Brunswick and Nova Scotia.
CBGA-1 left the air in early December 2014, after the aforementioned FM rebroadcasters on the Quebec side of Chaleur Bay were activated.
In 2017, Vista Radio has voluntarily surrendered the licenses for all of their low-power 50 watt AM transmitters in British Columbia. Vista stated that the transmitting equipment for these facilities are in state of disrepair and would not be economically viable to replace them. The former rebroadcasters affected were:
During the 1980s, rebroadcasters CKIG (CKDR-1), CKEF (CKDR-4), CKHD (CKDR-3) and CKSI (CKDR-2) would all adopt the CKDR callsign.
In 2002, VOAR added several FM rebroadcasters in various parts of the province, too far from St. John's to get a clear signal from the AM transmitter. Over the years, other rebroadcasters were added in other Canadian provinces and territories. VOAR is also carried across Canada on Bell TV Channel 950 and locally on Rogers Cable Channel 929.
CKCO-TV-2 was among a long list of CTV rebroadcasters nationwide that was set to shut down on or before August 31, 2009, as part of a political dispute with Canadian authorities on paid fee-for-carriage requirements for cable television operators. A subsequent change in ownership assigned full control of CTVglobemedia to Bell Media; as a result, CKCO-TV-2 remained in normal licensed broadcast operation.
The following rebroadcasters are not owned by the CBC, but by independent community groups.
The requirement that a full-service station maintain local presence in its community of license has been used by proponents of localism and community broadcasting as a means to oppose the construction and use of local stations as mere rebroadcasters or satellite-fed translators of distant stations. Without specific requirements for service to the local community of license, stations could be constructed in large number by out-of-region broadcasters who feed transmitters via satellite and offer no local content.
In 2002, CTV sold its four CBC affiliates in Northern Ontario, CHNB, CJIC in Sault Ste. Marie, CKNC in Sudbury and CFCL in Timmins directly to the CBC. All four ceased to exist as separate stations on October 27, 2002, and become rebroadcasters of Toronto's CBLT. CHNB's call sign was changed to CBLT-4. These translators closed on July 31, 2012, because of budget cuts at the CBC.
On November 7, 2012, the AMMSA received approval to supersede CFWE-FM Lac La Biche and four low-power rebroadcasters serving nearby reserves with a new 19.6 kW signal on 90.5 MHz in Lac La Biche. In 2016, CHWE-FM-4's power was increased from 9.3 kW to 100 kW. In September 2017, the AMMSA received approval to add a 100,000 watt transmitter at 105.7 MHz in Grande Prairie, which superseded low-power transmitters serving the Horse Lake Reserve and Duncan's Band Reserve.
Though CBFX-4 and CBFX-5 are technically rebroadcasters of CBFX, on-air idents show they actually rebroadcast Ottawa's CBOX-FM.
The station previously aired the regional morning program, Ontario Morning, produced by CBLA and airing on nearly all Radio One rebroadcasters in Southern Ontario. Prior to 2015, it aired CBLA's afternoon program Here and Now, but in that year Here and Now was replaced with Afternoon Drive. The latter show was previously produced at Windsor's CBEW, but moved to London at the same time as the launch of London Morning.
CBLFT operated almost 30 analog television rebroadcasters throughout the province Ontario and included communities such as London, Kitchener and Sudbury. Additionally, several Radio-Canada transmitters in eastern Ontario, such as Kingston and Belleville, were part of the CBLFT license even though they served cities that were closer to Ottawa than Toronto.
Due to cost-cutting measures at the CBC in the early 1990s, local programming on Toronto's CBLFT and its rebroadcasters, as well as CBLFT semi-satellite CBEFT in Windsor was discontinued in 1991. All Radio-Canada transmitters in Ontario (except the northwest, which was served by CBWFT in Winnipeg) were reclassified as rebroadcasters of CBOFT, under the name "Radio-Canada Ontario-Outaouais". The station produced two distinct newscasts through the 1990s and 2000s, one for the Ottawa region and one for the remainder of Ontario.
CBWFT operated 11 analog television retransmitters in Manitoba (e.g. Brandon) and Northwestern Ontario (in the parts of that region which fall in the Central Time Zone, e.g. Kenora). 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 or Radio-Canada's television rebroadcasters were converted to digital.
