One of the most popular shows on CBC Television is the weekly Saturday night broadcast of NHL hockey games, Hockey Night in Canada. It has been televised by the network since 1952. During the NHL lockout and subsequent cancellation of the 2004-2005 hockey season, CBC instead aired various recent and classic movies, branded as Movie Night in Canada, on Saturday nights. Many cultural groups criticized this and suggested the CBC air games from minor hockey leagues; the CBC responded that most such broadcast rights were already held by other groups, but it did base each Movie Night broadcast from a different Canadian hockey venue. Other than hockey, CBC Sports properties include Toronto Raptors basketball, Toronto FC Soccer, and various other amateur and professional events.

It was also the exclusive carrier of Canadian Curling Association events during the 2004–2005 season. Due to disappointing results and fan outrage over many draws being carried on CBC Country Canada (now called Cottage Life Television, the association tried to cancel its multiyear deal with the CBC signed in 2004. After the CBC threatened legal action, both sides eventually came to an agreement under which early-round rights reverted to TSN. On June 15, 2006, the CCA announced that TSN would obtain exclusive rights to curling broadcasts in Canada as of the 2008-09 season, shutting the CBC out of the championship weekend for the first time in 40-plus years.

Many were surprised by these changes to the CBC schedule, which were apparently intended to attract a younger audience to the network; some suggested they might alienate the core CBC viewership. Another note of criticism was made when the network decided to move The National in some time zones to simulcast the American version of The One over the summer. This later became a moot point, as The One was taken off the air after two weeks after extremely low American and Canadian ratings, and the newscast resumed its regular schedule.

Beginning in 2005, the CBC has contributed production funds for the BBC Wales revival of Doctor Who, for which it received a special credit at the end of each episode. This arrangement continued until the end of fourth season, broadcast in 2008. The CBC similarly contributed to the first season of the spin-off series, Torchwood. More recently, the network has also begun picking up Canadian rights to some Australian series, including the drama series Janet King and Love Child, and the comedy-drama series Please Like Me.

On March 5, 2005, CBC Television launched a high definition simulcast of its Toronto (CBLT-DT) and Montreal (CBMT-DT) stations. Since that time, the network has also launched HD simulcasts in Vancouver (CBUT-DT), Ottawa (CBOT-DT), Edmonton (CBXT-DT), Calgary (CBRT-DT), Halifax (CBHT-DT), Windsor, (CBET-DT), Winnipeg (CBWT-DT) and St. John's (CBNT-DT). CBC HD is available nationally via satellite and on digital cable as well as for free over-the-air using a regular TV antenna and a digital tuner (included in most new television sets) on the following channels:

Most CBC television stations, including those in the major cities, are owned and operated by the CBC itself. CBC O&O stations operate as a mostly seamless national service with few deviations from the main network schedule, although there are some regional differences from time to time. For on-air identification, most CBC stations use the CBC brand rather than their call letters, not identifying themselves specifically until sign-on or sign-off (though some, like Toronto's CBLT, do not ID themselves at all except through PSIP). All CBC O&O stations have a standard call letter naming convention, in that the first two letters are "CB" (an ITU prefix allocated not to Canada, but to Chile) and the last letter is "T". Only the third letter varies from market to market; however, that letter is typically the same as the third letter of the CBC Radio One and CBC Radio 2 stations in the same market. An exception to this rule are the CBC North stations in Yellowknife, Whitehorse and Iqaluit, whose call signs begin with "CF" due to their historic association with the CBC's Frontier Coverage Package prior to the advent of microwave and satellite broadcasting.

Some stations that broadcast from smaller cities are private affiliates of the CBC, that is, stations which are owned by commercial broadcasters but predominantly incorporate CBC programming within their schedules. Such stations generally follow the CBC schedule, airing a minimum 40 hours per week of network programming. However, they may opt out of some CBC programming in order to air locally produced programs, syndicated series or programs purchased from other broadcasters, such as CTV Two, which do not have a broadcast outlet in the same market. In these cases, the CBC programming being displaced may be broadcast at a different time than the network, or may not be broadcast on the station at all. Most private affiliates generally opt out of CBC's afternoon schedule and Thursday night arts programming. Private affiliates carry the 10 p.m. broadcast of The National as a core part of the CBC schedule, but generally omitted the 11 p.m. repeat (which is no longer broadcast). Most private affiliates produce their own local newscasts for a duration of at least 35 minutes. Some of the private affiliates have begun adding CBC's overnight programming to their schedules since the network began broadcasting 24 hours a day.

Private CBC affiliates are not as common as they were in the past, as many such stations have been purchased either by the CBC itself or by Canwest Global or CHUM Limited, respectively becoming E! or A-Channel (later A, now CTV Two) stations. One private CBC affiliate, CHBC-TV in Kelowna, joined E! (then known as CH) on February 27, 2006. When a private CBC affiliate reaffiliates with another network, the CBC has normally added a retransmitter of its nearest O&O station to ensure that CBC service is continued. However, due to an agreement between CHBC and CFJC-TV in Kamloops, CFJC also disaffiliated from the CBC on February 27, 2006, but no retransmitters were installed in the licence area. Former private CBC affiliates CKPG-TV Prince George and CHAT-TV Medicine Hat disaffiliated on August 31, 2008 and joined E!, but the CBC announced it will not add new retransmitters to these areas. Incidentally, CFJC, CKPG and CHAT are all owned by an independent media company, Jim Pattison Group. With the closure of E! and other changes in the media landscape, several former CBC affiliates have since joined City or Global, or closed altogether.

According to filings to the Canadian Radio-television and Telecommunications Commission (CRTC) by Thunder Bay Electronics (owner of CBC's Thunder Bay affiliate CKPR-DT) and Bell Media (owner of CBC affiliates CFTK-TV in Terrace and CJDC-TV in Dawson Creek),[citation needed] the CBC informed them that it will not extend its association with any of its private affiliates beyond August 31, 2011. Incidentally, that was also the date for analogue to digital transition in Canada. Given recent practice and the CBC's decision not to convert any retransmitters to digital, even in markets with populations in the hundreds in thousands, it is not expected that the CBC will open new transmitters to replace its affiliates, and indeed may pare back its existing transmitter network. However, in March 2011, CKPR announced that it had come to a programming agreement with the CBC, in which the station will continue to provide CBC programming in Thunder Bay for a period of five years. On March 16, 2012, Astral Media announced the sale of its assets to Bell Media, owners of CTV and CTV Two, for $3.38 billion with CFTK and CJDC included in the acquisition. Whether the stations will remain CBC affiliates or become owned-and-operated stations of CTV or CTV Two following the completion of the merger is undetermined.

CBC Television stations can be received in many United States communities along the Canadian border over-the-air and have a significant audience in those areas. Such a phenomenon can also take place within Great Lakes communities such as Ashtabula, Ohio, which received programming from the CBC's London, Ontario, transmitter, based upon prevailing atmospheric conditions over Lake Erie. As of September 2010 CBC shut down its analogue transmitter and decided not to replace it with a digital transmitter. As a result, there is now a giant hole in the coverage of CBC in South-Western Ontario. Both CBC - Toronto and CBC - Windsor are both over 100 miles from London, ON and out of range for even the largest antennas[citation needed].

CBC's sports coverage has also attained high viewership in border markets, including its coverage of the NHL's Stanley Cup Playoffs, which was generally considered to be more complete and consistent than coverage by other networks such as NBC. Its coverage of the Olympic Games also found a significant audience in border regions, primarily due to the fact that CBC aired more events live than NBC's coverage, which had been criticized in recent years for tape delaying events to air in primetime, even if the event is being held in a market in the Pacific Time Zone during primetime hours on the East (where it would still be delayed for West coast primetime).

While its fellow Canadian broadcasters converted most of their transmitters to digital by the Canadian digital television transition deadline of August 31, 2011, CBC converted only about half of the analogue transmitters in mandatory areas to digital (15 of 28 markets with CBC Television stations, and 14 of 28 markets with Télévision de Radio-Canada stations). Due to financial difficulties reported by the corporation, the corporation published digital transition plans for none of its analogue retransmitters in mandatory markets to be converted to digital by the deadline. Under this plan, communities that receive analogue signals by rebroadcast transmitters in mandatory markets would lose their over-the-air signals as of the deadline. Rebroadcast transmitters account for 23 of the 48 CBC and Radio-Canada transmitters in mandatory markets. Mandatory markets losing both CBC and Radio-Canada over-the-air signals include London, Ontario (metropolitan area population 457,000) and Saskatoon, Saskatchewan (metro area population 257,000). In both of those markets, the corporation's television transmitters are the only ones that were not planned to be converted to digital by the deadline.

Because rebroadcast transmitters were not planned to be converted to digital, many markets stood to lose over-the-air coverage from CBC or Radio-Canada, or both. As a result, only seven of the markets subject to the August 31, 2011 transition deadline were planned to have both CBC and Radio-Canada in digital, and 13 other markets were planned to have either CBC or Radio-Canada in digital. In mid-August 2011, the CRTC granted the CBC an extension, until August 31, 2012, to continue operating its analogue transmitters in markets subject to the August 31, 2011 transition deadline. This CRTC decision prevented many markets subject to the transition deadline from losing signals for CBC or Radio-Canada, or both at the transition deadline. At the transition deadline, Barrie, Ontario lost both CBC and Radio-Canada signals as the CBC did not request that the CRTC allow these transmitters to continue operating.

In markets where a digital transmitter was installed, existing coverage areas were not necessarily maintained. For instance, the CBC implemented a digital transmitter covering Fredericton, New Brunswick in the place of the existing transmitter covering Saint John, New Brunswick and Fredericton, and decided to maintain analogue service to Saint John. According to CBC's application for this transmitter to the CRTC, the population served by the digital transmitter would be 113,930 people versus 303,465 served by the existing analogue transmitter. In Victoria, the replacement of the Vancouver analogue transmitters with digital ones only allowed only some northeastern parts of the metropolitan area (total population 330,000) to receive either CBC or Radio-Canada.

CBC announced on April 4, 2012, that it will shut down all of its approximately 620 analogue television transmitters on July 31, 2012 with no plans to install digital transmitters in their place, thus reducing the total number of the corporation's television transmitters across the country down to 27. According to the CBC, this would reduce the corporation's yearly costs by $10 million. No plans have been announced to use subchannels to maintain over-the-air signals for both CBC and Radio-Canada in markets where the corporation has one digital transmitter. In fact, in its CRTC application to shut down all of its analogue television transmitters, the CBC communicated its opposition to use of subchannels, citing costs, amongst other reasons.

On August 6, 2010, the CBC issued a press release stating that due to financial reasons, the CBC and Radio-Canada would only transition 27 transmitters total, one in each market where there was an originating station (i.e. a CBC or Radio-Canada television station located in that market). Further, the CBC stated in the release, that only 15 of the transmitters would be in place by August 31, 2011 due to lack of available funds, and that the remainder would not be on the air until as late as August 31, 2012. Additionally, the CBC stated in the release that it was asking the CRTC for permission to continue broadcasting in analogue until the identified transmitters for transition were up and running. At the time of the press release, only eight of the corporation's transmitters (four CBC and four Radio Canada) were broadcasting in digital.

On November 30, 2010, CBC's senior director of regulatory affairs issued a letter to the CRTC regarding CBC's plans for transitioning to digital. The letter states, "CBC/Radio-Canada will not be converting its analogue retransmitters in mandatory markets to digital after August 31, 2011."  On December 16, 2010, some months after the CRTC issued a bulletin reminding broadcasters that analog transmitters had to be shut off by the deadline in mandatory markets, the CBC revised the documents accompanying its August 6, 2010 news release to state that it had the money for and is striving to transition all 27 transmitters by August 31, 2011.

On March 23, 2011, the CRTC rejected an application by the CBC to install a digital transmitter serving Fredricton, New Brunswick in place of the analogue transmitter serving Fredericton and Saint John, New Brunswick, which would have served only 62.5% of the population served by the existing analogue transmitter. The CBC issued a press release stating "CBC/Radio-Canada intends to re-file its application with the CRTC to provide more detailed cost estimates that will allow the Commission to better understand the unfeasibility of replicating the Corporation’s current analogue coverage." The press release further added that the CBC suggests coverage could be maintained if the CRTC were to "allow CBC Television to continue providing the analogue service it offers today – much in the same way the Commission permitted recently in the case of Yellowknife, Whitehorse and Iqaluit."

On August 18, 2011, the CRTC issued a decision that allows CBC's mandatory market rebroadcasting transmitters in analogue to remain on-air until August 31, 2012. Before that deadline, CBC's licence renewal process would take place and CBC's digital transition plans would be examined as part of that process. The requirement remains for all of CBC's full-power transmitters occupying channels 52 to 69 to either relocate to channels 2 to 51 or become low-power transmitters. In some cases, CBC has opted to reduce the power of existing transmitters to low-power transmitters, which will result in signal loss for some viewers.

On July 17, 2012, the CRTC approved the shut down of CBC's analogue transmitters, noting that "while the Commission has the discretion to refuse to revoke broadcasting licences, even on application from a licensee, it cannot direct the CBC or any other broadcaster to continue to operate its stations and transmitters." On July 31, 2012, at around 11:59 p.m. in each time zone, the remaining 620 analogue transmitters were shut down, leaving the network with 27 digital television transmitters across the country, and some transmitters operated by some affiliated stations.
