On DTV licences from the CRTC: There might be a misunderstanding here. The CRTC no longer issues separate licences for transitional DTV operations. Rather, they add transitional DTV stations to existing licences for analog stations. However, I've read nothing about the CRTC denying TV stations the opportunity to apply for transitional channels.
On CBRT going digital: If CBC audience relations is now saying a channel change is coming for CBRT, then that's news. As I've previously reported, they'd written in 2009 to say they were likely staying on VHF 9. A channel change for CBC is technically plausible. There are plenty of high-power UHF allocations available in this region.
