On March 9, 2012, Channel Zero-operated numbered company 2190015 Ontario Inc. was granted permission to move the station's broadcasts from VHF channel 11 to UHF channel 15 (which had recently been vacated by CKXT-DT-1), in response to poor reception of CHCH-DT along its fringes in the Greater Toronto Area, compared to its former analogue signal on VHF channel 11 and transitional digital signal on UHF channel 18. During the application process, the station also claimed that Mobile DTV services perform better in the UHF band, and this move would allow the station to plan for a potential Mobile DTV feed. Industry Canada stated that this application is technically feasible, though pirate broadcaster Star Ray TV, had broadcast in analogue on UHF channel 15 from a transmitter in The Beaches neighbourhood of Toronto. (Star Ray would convert to digital following CHCH's reassignment to channel 15, broadcasting on UHF channel 22.) Tri-State Christian Television's WNYB from Jamestown, New York also has a Buffalo-based translator, WBNF-CD, on UHF channel 15, which would require addressing by the CRTC due to the closer location of CHCH's transmitter to WBNF-CD.
