The station was originally launched in 1992 by Keith Dancy, the owner of AM radio station CJRN, as a tourist information station broadcasting at 91.9 FM with an effective radiated power of just 8 watts. The station operated under a series of short-term special events licenses, each initially covering either the summer tourist season or Niagara Falls' annual Winter Festival of Lights. The station's short-term licenses were granted as follows: May 29 - October 31, 1992, November 25, 1992 - January 17, 1993, May 3 - October 31, 1993, December 23, 1993 - January 31, 1995, April 7, 1995 - January 31, 1996, June 17, 1996 - January 31, 1997 and January 30, 1997 - August 31, 1998. In 1998, the station moved to its current frequency after the adjacent 91.7 was awarded to CHOW-FM in Welland. Later that year, the station was granted its first long-term license, covering the period from 1998 to 2005. In 2001, CFLZ and CJRN exchanged formats. CJRN took over the tourist information programming, and CFLZ adopted CJRN's music programming. The following year, CFLZ flipped formats with CKEY-FM, adopting its current adult contemporary format as CKEY, which is closer to the Buffalo market, became an urban CHR station. In 2004, CFLZ-FM increased their power from 406 watts to 7,200 watts and in 2006, CFLZ-FM decreased power from 7,200 watts to 4,000 watts. In 2010, the Haliburton Broadcasting Group applied to buy CKEY-FM and sister station CFLZ-FM. The transaction received approval on June 8, 2011.
2011–2013: 105.1 ED FM
On August 24, 2011, after playing Take Me To The River by Talking Heads, CFLZ dropped the hot adult contemporary format and began a two-hour stunt of Christmas music. After this, CFLZ adopted a variety hits format as 105.1 ED FM. In late 2011, the station adopted its current CJED-FM call letters. Sister station CKEY-FM's call letters were replaced with CFLZ-FM. On April 23, 2012, Vista Broadcast Group, which owns a number of radio stations in western Canada, announced a deal to acquire Haliburton Broadcasting, in cooperation with Westerkirk Capital. The transaction was approved by the CRTC on October 19, 2012.
On September 19, 2013, CJED dropped its adult hits format and branding and began stunting with Christmas music. The next day, at Noon, 105.1 flipped to CHR, branded as 2Day FM 105.1/101.1 and began simulcasting its sister station CFLZ-FM. On December 8, 2014, the CRTC denied an application by Vista Broadcast Group to amend the license of its sister station CFLZ-FM. It cited the company for being in non-compliance with various licensing conditions including deploying CJED-FM as a full-time rebroadcast transmitter without prior approval of the Commission. New conditions were placed upon the licensee. Both stations went silent shortly thereafter and returned to air on December 19, 2014 apparently continuing to utilize CJED-FM for simulcasting. The simulcast ended on July 15, 2016, when CFLZ flipped to adult hits as "Juice FM." 2Day FM remained on CJED.
2018–present: The River
On January 15, 2018 Byrnes Communications acquired CJED-FM and sister station CFLZ-FM with approval from the CRTC.. Byrnes Communications officially took over CJED on February 1, 2018. On March 1, 2018, the station switched to an adult contemporary format as "105.1 The River," returning to the format and brand it had carried from 2002 to 2011.
