They're temporary members of the National Energy Board whose job will be assigned to them by the chair of the National Energy Board. That is not the job of the Government of Canada, and the chair of the National Energy Board will determine the best way to deploy this increased capacity of the board to do its job. That will happen sometime after the application has been lodged. It won't be a long time after that, and it will enable the National Energy Board to do a better job than it could do if it didn't have these additional temporary members.
