CIHT-FM

The station was licensed by the CRTC in 2001, to broadcast a rhythmic contemporary/dance music format known as The Planet 89.9. The station launched on February 7, 2003, as The New Hot 89.9 under a rhythmic contemporary format, but flipped to its current format after 105.3 Kiss FM signed on the air in 2004. Both CIHT and CHBN-FM in Edmonton share the distinction of having been shifted from rhythmic contemporary to Top 40 in less than a year after their 2003 sign-ons.

Even while CIHT is the only English Top 40 station in Ottawa, it was one of the few Top 40 stations in Canada to continue supporting older music, making CIHT lean towards more of a hot adult contemporary direction than most Top 40 stations in Canada, but on March 31, 2014, CIHT picked up new competition with CKQB-FM's flip from active rock to a rhythmic-leaning CHR format, a move that prompted CIHT to back off from the hot AC fare and become more hit-driven with more currents.

The station produces the Stingray Hit List Countdown (formerly the Canadian Hit 40 and the Canadian Hit 30), a weekly countdown show that is syndicated to other Stingray sister stations.
