CIMT-DT, virtual and VHF digital channel 9, is a TVA-affiliated television station licensed to Rivière-du-Loup, Quebec, Canada.

The area's rugged topography renders the main CIMT signal more or less unviewable in the lower portions of the city.

As part of the Spectrum auction in Canada in 2016, CIMT-DT applied to move repeater CIMT-DT-6 on UHF 41 down to UHF 35, in line with international coordination with the FCC as a result of their 600 MHz band spectrum auction removing channels 38-51 from television service.

Ultimately, by November 24, 2021, CIMT-DT would instead be granted permission by the CRTC to move CIMT-DT-6 to the former CKRT-DT-3 facility, effectively restoring that transmitter to active use and decommissioning CIMT-DT-6.

The reasons cited were greater reliability and lower power usage (and thus, less expensive to run), as CKRT-DT-3 was on VHF 13 when it was shut down, as opposed to the UHF band the repeater occupied.
