On March 19, Radio Communautaire de la Rive Sud Inc. was awarded a licence for a French-language community FM station in Longueuil. It would broadcast on a frequency of 103.1 MHz and have an effective radiated power of 50 watts. This would be the first community radio station on the South Shore. The station would serve the 350,000 residents of Champlain, which included Longueuil, St-Hubert, Brossard, St-Lambert, Greenfield Park and Lemoyne. The main studio would be in Longueuil with satellite studios in St-Hubert and Brossard. Revenues would come from the average four minutes per hour of advertising, and the Quebec PAMEC program which was designed to assist local media.

CHAA-FM signed on the air on November 15.


CHAA was given permission to relocate the transmitter from the roof of the Charles-Lemoyne Hospital to the roof of the Pierre-Boucher Hospital. 


CHAA was granted a frequency change from 103.1 to 103.3 MHz and an increase in effective radiated power from 50 to 156 watts. 

Later in the year, CHAA was granted a power decrease to 104 watts. This request was made because the antenna was being replaced.


A power decrease to 53 watts was granted. This request was due to the proposed relocation of the transmitter to a site located approximately 8 kilometres west of the existing site.


An increase in effective radiated power to 64 watts was approved. 


On May 8 the CRTC approved the application by CHAA-FM to increase average effective radiated power from 64 watts to 340 watts and the maximum ERP from 263 watts to 1,400 watts. The goal of the proposed increase was to improve the quality of the station’s signal in its main authorized service area.


On August 31, the CRTC administratively renewed the licence for CHAA-FM to December 31, 2011.


On August 28, the CRTC administratively renewed CHAA-FM’s licence to December 31, 2012. On December 21, the licence was renewed to August 31, 2016.


On May 29, the CRTC approved CHAA’s application to increase the maximum ERP from 1,400 to 1,700 watts, decrease the average ERP from 340 to 320 watts, increase the EHAAT from 192.5 to 284.6 metres and relocate the transmitter site. The licensee also proposed to use the subsidiary communications multiplex operation channel.


CHAA received CRTC approval in May to increase ERP from 1,400 to 1,700 watts, to relocate the transmitter, and to increase antenna height.


In the summer, CHAA began broadcasting in HD. The station`s regular programming was broadcast on CHAA-FM HD1 with additional HD channels planned for the future.
