Sure. As I said, the EA review process, which began in 2016, was something that included the review of the project list. The basis for that review included starting with the existing project list in CEAA, 2012, and looking internally at what projects had typically come through the process.
The project list is actually fairly extensive and there were a number of projects that we typically saw coming through the system. There were others that we didn't see a huge number of projects. There were also changes, of course, over the past seven years since CEAA, 2012, came in in terms of regulatory frameworks. We looked at that with all of the expert federal departments that typically support us through an environmental assessment, and then also with the life-cycle regulators that I mentioned. In doing that, we determined what projects had the greatest potential for significant impacts on areas of federal jurisdiction in light of the other regulatory frameworks.
