'Add on required' for Sportsnet+ live channel streams?

For years ive been signing into sportsnet's site to watch their live channels by using the 'sign in with tv provider' and using my videotron username and password

As of 2 days ago, its now telling me i need an 'add on required' in order to watch their regular live channels. 

Curious if anyone else has been seeing this lately, or if its something going on with my account behind the scenes?

Thanks
