Transmitters in small markets with one (or no) originating stations were, in most cases, not required to convert to digital even if operating at full power. Transmitters broadcasting on UHF channels 52–69 were required to vacate the channels by August 31, 2011; some (such as a CKWS-TV re-transmitter in Brighton, Ontario, and three TVOntario sites) went digital as part of a move to a lower frequency but do not provide high-definition television, digital subchannels or any functions beyond that of the original analogue site.
