Over-the-air Digital Television Transition

Main article: CBC Television See also: Digital television in Canada

The CRTC ordered that in 28 "mandatory markets", full power over-the-air analogue television transmitters had to cease transmitting by August 31, 2011. Broadcasters could either continue serving those markets by transitioning analogue transmitters to digital or cease broadcasting over-the-air. Cable, IPTV, and satellite services are not involved or affected by this digital transition deadline.

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 to digital (15 of 28 markets with CBC TV, and 14 of 28 markets with SRC). Due to financial difficulties reported by the corporation, the corporation published a plan whereby communities that receive analogue signals by re-broadcast transmitters in mandatory markets would lose their over-the-air (OTA) signals as of the deadline. Rebroadcast transmitters account for 23 of the 48 CBC and SRC transmitters in mandatory markets. Mandatory markets losing both CBC and SRC over-the-air signals include London, Ontario (metropolitan area population 457,000) and Saskatoon, Saskatchewan (metro area 257,000). In both of those markets, the corporation's television transmitters are the only ones that were not converted to digital.

On July 31, 2012, CBC shut down all of its approximately 620 analogue television transmitters, following an announcement of these plans on April 4, 2012. This reduced the total number of the corporation's television transmitters across the country 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 SRC 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, amongst other reasons, costs. However, few Canadians actually lost access to CBC and Radio-Canada programming due to the very high penetration of cable and satellite, which in some areas (particularly remote and rural regions) is all but essential for acceptable television.
