It broadcasts an adult contemporary format branded as Mountain FM.

The station was founded in 1981 by Mountain Broadcasting, which was sold to Selkirk Communications in January 1989.

Selkirk, in turn, was sold to Maclean-Hunter in September 1989, and CISQ was resold to Rogers Communications as part of the purchase.

This relocation will result in a decrease in the average effective radiated power (ERP) from 586 to 474 watts (directional antenna with a decrease in the maximum ERP from 1,430 to 1,000 watts) as well as an increase in the effective height of antenna above average terrain from -306.2 metres to -238.3 metres.

Then in March 2015, Rogers switched the call sign of CKKS-FM in Sechelt to CFUN-FM for a Rogers-owned station serving Metro Vancouver and the Fraser Valley.
