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.
