CBC's Waterloo Region morning show returned to 89.1 FM at 6 a.m. on Friday morning.
The broadcast licence for the region was approved by the CRTC Thursday afternoon. The licence will run until 2019.
The CBC had filed an application for the station with the CRTC in June 2012. It also submitted a follow up clarification in September 2012 and filed a reply to interventions in December 2012.
