On December 3, 1986, Mervyn Russell, representing a company to be incorporated received approval from the CRTC to operate a new FM radio station at Saint John. The station began broadcasting in 1987 with Gary Crowell as the GM, and Jim Goldrich returned to K100 from working at CJYQ in Newfoundland. K100's original studios and offices were on 400 Main Street in Place 400. In the mid-1990s, K100 moved their studios and offices to Union Street, where they are still located. In 1997, the station was purchased by Newcap Broadcasting and was re-purchased by MBS Radio in 2005.
