Perhaps I can answer part of that.
With respect to the amendments to NWPA, I think the changes being proposed to the legislation would identify minor works from a navigation perspective. That doesn't mean there wouldn't be the possibility of an environmental assessment being undertaken should a project be proposed that could damage that waterway--if, for example, it constitutes fish habitat. So if fish are there, the Fisheries Act is another trigger for CEAA, or if there's federal funding going into a project, but I think it's fair to say that the trigger for EA would be lost if that type of waterway were deemed to be a minor waterway.
