In addition, CHWI-TV-60 has been authorised to relocate its analog transmitter to channel 26, and to switch its digital allotment from UHF channel 25 to channel 26, due to the phaseout of UHF channels 52–69. However, the CRTC decision did not address potential co-channel interference issues with WLPC-LP in Detroit, which also broadcast its analog signal on channel 26 (an unprotected frequency); as a result, that station went silent during much of 2011, not returning to air until November of that year as WLPC-LD (now WLPC-CD), on digital channel 40 with its sole companion PSIP (or virtual channel) of 40.1.
