Jeff will come back on the last part of the question.
But I'd like to clarify, Chair, that in terms of no governance, I think it's really important for me to mention that if I misled the committee, again, I apologize. I certainly did not want to leave the impression that there's no governance with respect to these issues. In fact, it's quite the opposite. We take our role very seriously as regulators in the federal government of these major resource projects and have been working hard and long at putting in effective regulatory practices over the last number of years—and decades, I would argue.
In fact, we continue to look at it on a daily basis: how pipelines operate in a safe and secure manner; how we can do environmental assessments in a time-oriented but effective way. We've put in means and mechanisms over the last four years that, we would argue, are amongst the world's best—the environmental certificating process and on we go. So the NEB does take its role very seriously. I would never want to leave this committee with an impression that there is no governance. In fact, we exist to do that. That's why we're here at this table.
Jeff, answer the specific question on the reviews, please.
