I think it would be useful to discuss the definition of minor works and have a good debate on that. From a DFO perspective we certainly don't classify waterways as minor works or major works. If there's fish and fish habitat, we're there.
If the real concern is whether an environmental assessment will be done or not, I think the issue is whether there's a federal regulator that will be doing that, and what the value-added is of NWPA being another federal regulator on the same project.
