CJSA signed on in 2004, adopting a frequency formerly used by
CHIN as a
rebroadcaster to fill in reception gaps. CHIN's FM rebroadcaster now airs on 91.9 FM. The station began its broadcast on August 20 that year from its facility in
Scarborough, moving to its current facility in
Etobicoke in late 2004. Operated by the town's chamber of commerce, that station voluntarily surrendered its broadcast license in 2002. The former CJSA has no relation to the current CJSA-FM in Toronto. In December 2013, CJSA signed on
HD Radio operations. In a December 2012 letter to the CRTC, the station stated that it was interested in broadcasting up to 5 HD Radio subchannels, each of a different language for a different ethnic population (HD2 being Tamil, HD3 being
Punjabi, HD4 being
Hindi and
Urdu, or "
Aboriginal", and HD5 being
data transmission). On January 14, 2014, CMR launched one of Canada's first ever HD Radio broadcasts, with a 24-hour,
Tamil-language program on their HD 2 subchannel. CJSA is the second Canadian radio station to use the technology, the first being
CING-FM in
Hamilton. ==References==
