CHNC went on the air as an AM station on December 23, 1933, and it was originally an affiliate of the Canadian Radio Broadcasting Commission from 1933 to 1936 when it became an affiliate of Radio Canada.

On March 3, 2008, Radio CHNC ltée has received approval by the CRTC to convert the AM transmitters to the FM band and include addition of FM transmitters in Carleton, Chandler and Percé, Quebec.[1] As of late 2008, the new FM signals began on December 23, 2008.[2]
On October 21, 2011, the CRTC approved an application by Coopérative des travailleurs CHNC to change the technical parameters for the mother station CHNC-FM by increasing the average effective radiated power (ERP) from 3,400 to 4,100 watts (maximum ERP from 5,350 to 6,500 watts and effective height of antenna above average terrain (EHAAT) from 180 to 200 metres). The licensee also received approval to modify CHNC-FM-1's EHAAT by increasing it from 395 to 418.5 metres and changing CHNC-FM-2's frequency from 98.3 to 98.1 and increasing the average ERP (for CHNC-FM-2) from 550 to 810 watts (maximum ERP from 870 to 1,280 watts).[3]
