In 1986, CFNO received approval to add a transmitter at Nipigon/Red Rock at 103.7 MHz. However, the station was advised to seek another frequency for the rebroadcaster instead. CFNO-FM eventually established a transmitter in Nipigon at 100.7 MHz.
In 1988, CFNO received approval to add a transmitter, CFNO-FM-6, at Dubreuilville at 93.9 MHz. In 2004, the station was authorized to delete CFNO-FM-6 as that transmitter was no longer required, for reasons unknown.
On October 6, 2015, the CRTC approved changes to the authorized contours of CFNO-FM-2 Hornepayne, by increasing the effective radiated power from 4 to 280 watts and the effective height of antenna above average terrain from 17.5 to 37 metres. As a result of the increase in power, the transmitter’s status will change from that of a low-power, unprotected service to that of a protected Class A1 service. 
CJWA-FM in Wawa was also formerly a rebroadcaster of CFNO. North Superior launched a separate station there in 1998, after the town's sole local radio station (also going by the CJWA callsign, but at 1240 AM) was closed in 1996. CFNO's former rebroadcaster in Chapleau also became a rebroadcaster of CJWA's signal instead.
North Superior sold CJWA at the same time as CFNO, although to a different new owner, Labbe Media.
