I can confirm that the victims who registered with the board to receive the information are contacted. Certainly some victims don't know that they have access to the information from the Parole Board and Correctional Service Canada.
When victims are registered with the board, we contact them to ensure that they can participate in the process or that they can share their concerns regarding the offender's release conditions.
I can't assure you that all victims are registered because not all victims have registered with the board.
