So toʻnight I can't even find the game on the app on my internet TV. I am watching thru a bell streamer. I can find the game on the app on my tablet and it seems to be about 30 seconds ahead of the cable tv
So,
Your smart TV, not even showing up let alone showing as a blackout,
Your Bell streamer, no problem
Your cell/tablet, no problem. (presumably off wifi)
So, the issue doesn't appear to be related to your internet connection being geo identified as out of market, rather the specific device you're viewing on.
My best guess is Bell stores MAC addresses in a database to identify the geo location, and somehow your Smart TV got misidentified as in a different Geo location. Alternatively, it could be something to do with the app used by your smart tv, I know at least in my experience, Roku tends to be a bit flaky with the TSN app (more about crashing) and some TV's have very minimal updating of their OS and apps
