On March 20, Radio Communautaire de Chateauguay CHAI-MF received a licence for a new French-language community FM station at Chateauguay. It would broadcast on a frequency of 102.9 MHz with an effective radiated power of 50 watts. The filing of the application was not completed until after the CRTC’s freeze on FM (to allow the CBC time to complete a study on the utilization of frequencies). The Commission decided to consider the application on the basis that a specific frequency would not be assigned until the FM allocation plan was finalized. Departing from the usual restrictions on advertising on community stations, the CRTC has permitted as much as ten minutes per clock hour of conventional advertising on the new station.

The station received permission to move to 101.9 MHz with an effective radiated power of 50 watts. 

CHAI-FM signed on the air later in the year (target date was September 1). CHAI-FM was funded by the Quebec provincial government. A McMartin FM transmitter was used.


Paul Desruisseaux passed away at age 76. He was a lawyer, senator, and former owner of La Tribune, CHLT-AM-TV and CKTS-AM.


On January 11, the CRTC renewed CHAI-FM’s licence until September 30, 1985.


CHAI-FM increased its weekly broadcasting time from 84 to 116 hours.


English-language programming on CHAI was reduced from 15 to 9 hours per week.


On July 9, Radio Communautaire de Châteauguay inc. was given approval to increase the effective radiated power of CHAI-FM from 50 watts to 100 watts.


On September 6, CHAI was authorized to operate a synchronous transmitter in Candiac, operating on 101.9 MHz with average effective radiated power of 47 watts. The new transmitter would enable CHAI to serve most of the population in the territory of the regional county municipality of Roussillon located in the communities of Mercier, Delson, Candiac, Laprairie, St-Constant and Ste-Catherine. 


The Candiac synchronous transmitter – CHAI-FM-1 went on the air.


On August 8, the CRTC administratively renewed the licence for CHAI-MF CHAI-FM Châteauguay, and its transmitter CHAI-FM-1 Candiac, until August 31, 2013.


On November 24, the CRTC approved CHAI’s application to relocate the transmitter on top of the Châteauguay water tower, change the radiation pattern from non-directional to directional and to increase ERP from 100 to 167 watts (max. from 100 to 274 watts) and EHAAT from 50 to 69.52 metres.
