CHLO (530 kHz) is a commercial AM radio station in Brampton, Ontario, serving Greater Toronto.

Some Italian, German, Croatian, Tagalog, Bulgarian, and Spanish language shows are heard on weekends.

CHLO's radio studios and offices are on Dundas Street West in the Eatonville neighbourhood of Toronto.

In the 1960s, Alekos Columbos hosted a 90-minute Greek radio show on Saturdays and Klaas Mulenar preached in Dutch on Sundays, as the station incorporated more ethnic broadcasts into its schedule.

The station adopted the new call sign CIAO in 1987, and moved to its current frequency in 1991 after CJFT in Fort Erie converted to the FM band.
