I've been going through reddit threads that are littered with tons of people complaining about this. In the viewing region but for whatever reason, being blacked out by TSN. Often only on 1 of their devices like their smart TV, while it works fine everywhere else. Sometimes it'll work on that device for 1 game, then not the next, according to the claims.
Using a VPN didn't work for me at all and won't play anything on TSN Go, but I read that using a Location changer can work. I've set that up on my phone and will see if it works at game time! Fingers crossed.
