The station was launched in 1948 as CKPR-FM, an FM simulcast of CKPR. The station appears to have launched distinct programming in the fall of 1975, the same year the callsign was changed to CJSD-FM.
Throughout the 1980s, the station repeatedly received only short-term license renewals due to regulatory violations, including its musical selections, its failure to comply with CRTC rules around spoken word programming, and its failure to submit logger tapes of its programming to the commission.
