The station was licensed by the CRTC in 2001 to program a Dance format as "The Planet." The New Hot 89.9 first aired on February 7, 2003 under a rhythmic CHR format, but flipped to its current format after 105.3 Kiss FM signed on in 2004. Both CIHT and CHBN-FM in Edmonton share the distinction of having shifted from rhythmic top 40 to Top 40 in less than a year after their 2003 sign-ons.
Ottawa was the largest market Newcap owned radio stations until its expansion into Toronto and Vancouver in 2014, thanks to the purchase of five stations from a blind trust ran by Bell Media as part of their merger with Astral Media. Even while they were the only English top 40 station in Ottawa, it is one of the few top 40 stations in Canada to continue supporting older music, making CIHT lean more hot adult contemporary than most top 40 stations in Canada, but on March 31, 2014, CIHT picked up new competition with CKQB's flip from active rock to a Rhythmic-Leaning Top 40/CHR presentation as "JUMP 106.9," a move that prompted CIHT to back off from the Hot AC fare and become more hit-driven with more currents.
The station carries a syndicated national show, the Canadian Hit 30 Countdown, which is a locally produced show hosted by Mauler and Rush.
On April 1, 2010, the station temporarily changed its name to "Ho 89.9" as part of a contest. According to the station, the "T" from the slogan has been stolen, and there is a $10,000 cash prize to be awarded to the listener who follows the clues to locate the hidden "T". Three clues were given out daily.
The missing "T" was found at "Rooms by Design" on Highway 31 in Greely.
