Why is there lag between a live game on TV and the Sportsnet+ stream?

The lag time compared to live broadcast is dependent on the device being used, the location and connection of the user, and other factors. The lag time is typically between 30-60 seconds.

Because internet streaming lags behind television, your sports apps may send off a notification of a goal or a result before you have seen it. If you wish for this not to happen, you must disable your game alerts/notifications.
