I think the point is that in my understanding, the way the act is currently structured, the named works are dealt with in a very specific manner, even though in some cases those very works may not be of concern from a navigation safety point of view. The proposed change, as I understand, involves providing Transport Canada with greater flexibility to decide how the review and approval of particular projects should proceed, and there could be situations where they would not need a review and approval that is as in-depth as they currently receive.
It's not to take them off completely, but it's to provide greater flexibility to the department in order to design the assessment and approval process to match the project circumstances.
