CHRS-FM is a radio station broadcasting at 105.7 MHz in Toronto, Ontario, Canada. It is owned and operated by Rogers Sports & Media and broadcasts a Top 40/CHR (Contemporary Hit Radio) format branded as KiSS 105.7. Its studios are located at the Rogers Building at Bloor and Jarvis Streets in downtown Toronto, while its transmitter is located atop the CN Tower.

CHRS-FM's history dates back to 1961 when it first signed on as CHFI-FM, a sister station to CHFI-AM. Initially, CHFI-FM broadcast a beautiful music format, which was a staple of FM radio in its early years.

In 1986, CHFI-FM transitioned to a soft adult contemporary format.

The station adopted the CHR format and the KiSS branding in 1992. The call letters were changed to CHUM-FM to reflect its ownership under CHUM Limited.

In 2007, CTVglobemedia acquired CHUM Limited, and in 2011, Rogers Communications acquired CTVglobemedia's broadcasting assets, including CHUM-FM. At this point the call letters changed to CHRS-FM.

KiSS 105.7 is a consistently popular radio station in the Toronto market, known for playing current hit music and featuring on-air personalities. It competes with other Top 40 stations such as CKIS-FM (KiSS 92.5) and CIDC-FM (Z103.5).
