### Region

Canada

### Provide a description that is worded well enough to be understood

I get an "unsupported url" error when trying to download from a supported site, gem.cbc.ca.
Expected outcome: the video should download.

I'll note cbc gem isn't completely broken.  I also tried to download https://gem.cbc.ca/the-passionate-eye/s03e06, and that one worked.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
