1967
Robert Redmond's Radio Station CHSC Ltd. launched CHSC-AM and FM on March 20. It was a most unusual move - being able to launch brand new AM and FM stations on the same day. CHSC-AM operated on a frequency of 1220 kHz, and had a power of 1,000 watts day and 500 watts night. A single directional pattern was used for day and night operation. The six towers were located at a site on Lot 32, Thorold Township, Welland County - Collier Road, just north of Beaver Dam's Road. Studios and offices were at 36 Queenston Street. The "SC" in the calls: St. Catharines. William Stoeckel was general manager. John Tyrrell was named national sales manager.

Slogan: All Family Radio.

1972
CHSC applied to change its frequency to 1600 kHz. It was not alone. CFRS (1560) Simcoe, CKOT (1510) Tillsonburg and CHIN (1540) Toronto also wanted the frequency. There were also two applications for new stations at Guelph and at Waterloo, using the adjacent frequency of 1590 kHz. 1600 kHz had been used in the region by CJRN Niagara Falls - now on 710 KHz. CHIN wanted 1600 for night-time use only. It would continue to use 1540 during the day. CHIN also felt that if it got 1600 for night use, the channel might still be of use to any of the other applicants - especially during the day.

1973
On July 9, CFRS Simcoe was authorized to move to 1600 kHz and operate with a power of 10,000 watts, day and night. The change was originally approved February 28 but required clearance from the Department of Communications which was now given. The other applications for 1600 kHz and for 1590 kHz were turned down.

1978
On May 26, Radio Station CHSC Ltd. was authorized to increase the power of CHSC  from 1,000 watts day and 500 watts night to 10,000 watts full-time. The transmitter site would move from Collier Road, near Beaver Dams Road to Turner Road, two miles east of Turner’s Corners, Thorold Township.

1979
On May 22, CHSC-FM was authorized to continue simulcasting CHSC-AM between 6 and 9 a.m. This was due to the AM station's limited signal performance in the morning hours. Simulcasting on FM allowed CHSC to reach more listeners. The AM power increase granted in 1978 had still not become effective because the Department of Communications had not yet issued a technical certificate. The simulcast on FM could continue until the AM power increase took effect. It should be noted that both stations simulcast during the overnight hours.

CHSC-FM changed its call sign to CHRE-FM.

1980
CHSC 1220 increased power to 10,000 watts. Different day and night directional patterns were generated, using nine towers from a new transmitter site.

1984
CHSC/CHRE's news director was Frank Fanstone.

Ken Coughlin joined CHSC for afternoon drive from CJYQ in St. John's. Neal Kelly joined the news department.

1987
Bob MacGregor was CHSC's morning man.

1988
Former news director Jim Marino was now mayor of Niagara-on-the-Lake.

1989
Robert Redmond announced his intention to sell CHSC so that he could concentrate on FM operations in St. Catharines, Calgary and Toronto. CHSC would be sold to Stetco Inc., controlled by St. Catharines advertising executive Douglas Setterington.

1990
On March 31, CHSC and the building that housed both the AM and FM stations was sold to Coultis Broadcasting Ltd., 53% owned by Douglas S.K. Settrington. Setterington was a former employee of CHSC. He felt the station was a product which he could promote and make even more successful. Bob Redmond said he would continue his commitment to the community with CHRE-FM and that the sale of CHSC would enable both stations to establish clear identities and reach their full potential.

By agreement, CHRE-FM was allowed to continue using the FM studios in the CHSC building, but separate offices had to be found for administration, marketing, creative, promotion, programming and accounting. They ended up five miles away from the studios. It was then announced that CHRE would relocate to CorBloc, a new office and retail complex in downtown St. Catharines.

2001
CHSC applied to convert to the FM band, operating on 107.5 MHz with 3,000 watts. The application was withdrawn as Industry Canada hadn't approved the frequency.

2002
On June 19, the sale of CHSC to Pellpropco Inc. from Coultis Broadcasting Ltd. was approved. At this time, CHSC was under the temporary management authority of KPMG Inc., the receiver of Coultis Broadcasting Limited. Pellpropco was jointly owned by Fabrizio Pellegrino and Terrance Gertner (50% each).

2005
Robert E. Redmond, founder of CHSC 1220 passed away on May 7.

2006
The CRTC denied an application by Pellpropco Inc. (Pellpropco) to amend the licence for CHSC to authorize it to devote up to 40% of its programming to third-language programs. The decision noted the licensee's admitted non-compliance with the requirements of Public Notice 1999-117 and section 7(3) of the Radio Regulations, 1986 (the Regulations), which states that non-ethnic commercial radio stations may not devote more than 15% of their schedules to third-language programming. The decision also noted Pellpropco's failure to file its annual return for the broadcast year ending 31 August 2005, as required under section 9(2) of the Regulations. Finally, the Commission noted its longstanding practice of denying licence amendments requested by licensees that are in non-compliance with their regulatory obligations.

2009
On June 30 the CRTC issued mandatory orders directing Pellpropco Inc. to comply at all times with the requirements set out in sections 2.2(8), 7(3), 8(4), 8(5), 8(6) and 9(2) of the Radio Regulations, 1986 relating to the broadcast of Canadian music, the broadcast of third-language programming, the provision of complete logger tapes and program logs, and the filing of annual returns and financial statements. In addition, the Commission required the licensee to operate CHSC under additional conditions of licence pertaining to the broadcast of ethnic and third-language programming between 6 a.m. and noon from Monday to Friday and the provision of English-language news on weekends. The Commission also required that the licensee submit certain ownership-related information and documents within 30 days of the date of this decision.

In addition, the Commission received complaints alleging that since 2006 Pellpropco had reoriented CHSC's programming to serve Toronto's Italian-speaking community rather than the community it is licensed to serve, St. Catharines. Following an assessment of the complaints filed with the Commission and the licensee's response and in view of CHSC's various instances of apparent non-compliance during the current licence term, the Commission called Pellpropco to a public hearing in Orillia to show cause why a mandatory order requiring it to conform to the Regulations relating to Canadian content, the broadcasting of third-language programming, the filing of complete annual returns, and the provision of logger tapes, program logs and music lists should not be issued. The Commission also indicated that it might wish to discuss certain local programming issues, including the extent to which the local programming content and programming orientation provided on CHSC are of direct and particular relevance to St. Catharines and the surrounding area, the community CHSC is licensed to serve. The Commission signalled the possibility of imposing a new condition of licence relating to the licensee's broadcast of local programming content and its programming orientation. Further, the Commission indicated that certain ownership issues might be discussed.

At the hearing, the Commission questioned the licensee concerning the existing Management Agreement between Multimedia Management Limited and Pellpropco Inc. Following a discussion, it was found that Mr. Dominic Pellegrino, the owner of Multimedia Management Limited, was given the responsibility for the day-to-day operation of CHSC. However, the licensee Pellpropco reassured the Commission that it remains in full control of its decisions and that Multimedia Management Limited is reporting to the Board of directors for any decisions to be made.
