A series of rebroadcast transmitters relay the CIII signal to much of Ontario. Most of these use the CIII base callsign followed by a number to denote their status as rebroadcasters, except in Sudbury and North Bay where the CFGC callsign is assigned. The most likely explanation for using CFGC is that the close resemblance between the number 1 and the letter I would make CIII-TV-11 an undesirable call sign for Sudbury, while North Bay could not use CIII-TV-2 as that call sign is already in use in Bancroft.
