Part of my role is to provide the front-line functional guidance in matters related to a regulatory change and policy change. We have a process set up whereby we would issue what's called a “shift briefing” in an operational bulletin. It will reference back to the various authorities governed by Transport, and step-by-step instructions will be issued to the front-line staff so that they understand what the form looks like, how it's applied for and what it means in terms of the application of the various requirements at the border.
