With respect to any changes to the guidance itself, that's more, I would say, a straightforward process in some regards, but it is important that the guidance still be consistent with the intent of the regulations themselves. The guidance could not surpass the parameters set out in the regulations.
It would be difficult to say. Probably because it's developed through the Canadian Council of Motor Transport Administrators, there is a need to work towards consensus. It's difficult to estimate what kind of information and how much time that might take, but it is not as administratively complicated as making a change to the regulation itself.
