The signal from CBUT-DT, real CH-43 appears on the 'Pending Applications' version of your TV Fool Report.

It would appear that either Chuckanut or Lookout Mt. is obstructing your view toward Mt. Seymour where the CBUT transmitter is located.
The extremely weak signal level, -128.7 dBm and noise margin, -37.8 dB imply you would need an antenna with forward gain of about 50 dBd. I'm not sure if deep space radio-astronomy antennas achieve such performance. It's certainly far beyond the performance of any consumer grade antenna. (Your HD8200 is among the highest performing all channel antennas available.)
The old analog signal on VHF CH-2 was more powerful, passed over terrain a bit better than UHF and your TV would display the weak analog signal rather than loosing 'digital lock'.
Unless you can consider
remote location of your antenna, or an extreme tower, I don't see a way for you to receive much, if any, stations transmitting from Mt. Seymour, Vancouver, BC.
