CKTO-FM is a Canadian radio station, broadcasting at 100.9 FM in Truro, Nova Scotia.

The station airs an adult hits format and is branded as Bounce 100.9, which has a wide coverage area over much of western and central Nova Scotia and Prince Edward Island.

The station first began broadcasting in March 1965 originally as CKCL-FM before adopting its current call letters.

In 2002, the station rebranded to "Big Dog 100.9" with a rock-leaning Hot AC format.

As part of a mass format reorganization by Bell Media, on May 18, 2021, CKTO flipped to adult hits, and adopted the Bounce branding.
