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.

paragraph_text: 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.
