CIOK-FM
radio station in New Brunswick, Canada
CIOK-FM (100.5 MHz) is a Canadian radio station in Saint John, New Brunswick, owned by the Maritime Broadcasting System. The station currently offers an adult contemporary format branded on-air as K100. Prior to July 2009, it had an adult contemporary format before changing to CHR/Top 40. As of September 2015, the station moved back to AC.
Format
The format change happened a little after the same time CFQM-FM in Moncton changed from an Adult Contemporary format, to a Classic Hits format in July 2009.
CIOK was being programmed out of Moncton and in order to cut costs, MBS decided that instead of flipping CIOK to a classic hits format they would change the format to a CHR/Top 40 format to more effectively compete with rival CHWV-FM. CIOK-FM's switch to CHR joined sister station CKCW-FM in Moncton, which moved from top 40 to hot AC by that same time. Nielsen BDS later moved the station to the Canadian hot adult contemporary panel after the flip of this station to top 40. In September 2015, the station returned to adult contemporary.
History
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 CIOK from working at CJYQ in St. John's, Newfoundland and Labrador.

Why this record matters
“CIOK-FM” is worth following because a concise public description often conceals a longer documentary argument. Here, CIOK-FM, radio and station provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Feb 24, 2026. The linked authority identifier is Q45971. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2009, 2015, 1986 and 1987.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
