Trust Communications applied twice for a new station in Kitchener-Waterloo with its own schedule and studios, but these applications were rejected in favour of CJTW-FM.

Trust Communications applied for a transmitter to serve the Inuit residents of Iqaluit, Nunavut with the first Christian station in the territory (which would rebroadcast CJLF-FM); however, this application was rejected.

On September 28, 2011, the CRTC denied Trust's application to increase CJLF-FM-1's power in Owen Sound.

On January 28, 2011, the CRTC revoked the licence of CKLN-FM for regulatory non-compliance. The decision was appealed to the Federal Court of Canada, which denied the appeal on April 15, 2011. The CRTC subsequently issued a call for applications to occupy the now-vacant 88.1 FM frequency on September 28, 2011. Trust Communications filed an application to launch a new Christian music radio station in Toronto. The CRTC rejected Trust Communication's application on September 11, 2012, in favour of a new station, CIND-FM, owned by Rock 95 FM.
