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.
