There are a number of different regulatory considerations for projects. When you look at essentially any major project, there is typically provincial as well as federal regulation of some sort that comes into play.
In terms of its rationale, the Impact Assessment Act really is designed as a planning tool to look at the impacts of major projects. Projects that are not on the list were ones that for the most part either were formerly on the list or ones that, in addition to those, were considered but already have a regulatory framework of some sort around them for managing the interests that fall within federal jurisdiction.
Specifically, if you look at impacts on migratory birds or on climate change—those different areas—those are the things that were taken into account when we were looking at these projects.
