CKLO-FM is a radio station broadcasting a classic rock format on the frequency 98.1 FM in London, Ontario, Canada.

CKLO's studios are located on Richmond Row in downtown London, while its transmitter is located near Highway 401 near Veterans Memorial Parkway southeast of London.

Owned by Blackburn Radio, the station received CRTC approval on February 2, 2009.

[1] On October 15, 2010, Blackburn applied to increase CKLO's effective radiated power from 4,000 to 12,600 watts (directional antenna with a maximum ERP from 7,000 to 40,000 watts), by increasing the effective height of antenna above average terrain from 106.5 to 150 meters and by changing the transmitter site.
