Not long after bringing the station on-air, the Simards soon discovered that the area's rugged topography made it all but unviewable in the lower, western parts of the city. To solve this problem, CKRT applied for and received permission to sign on a "nested" rebroadcaster in Rivière-du-Loup, CKRT-TV-3, on channel 13. The repeater signed on in 1964 and mainly serves the western portion of the city. All other stations in the region eventually followed CKRT's lead. Earlier that year, it moved to its current studio in Rivière-du-Loup.
