I can elaborate.
Basically, all the departments that charge user fees do so individually under their regulations generally. What the Transport Canada folks who were just presenting were talking about were non-regulatory areas where the administrator would enter into an agreement to charge fees on a voluntary basis. They're quite complex and subject to each department's stakeholders, industries, and consultations.
All that is governed by the principles of the service fees that Treasury Board is bringing forward, but some departments have been in this business quite a long time and have very robust frameworks already.
