We've had to make choices about putting our priority on what changes, what recommendations, we should address first in terms of ensuring the greatest of value from a safety point of view. For example, one recommendation was to enhance our safety management system regulations. Another was to conduct effectiveness audits of those requirements. Our first step was in 2015 to bring in the new SMS requirements. Our second step was to make sure that companies had properly implemented them, and we're now turning our attention to doing effectiveness audits, as I suggested, in September of 2021. I think Mike might also be able to provide a little bit more detail in terms of some of the work we've done subsequent to Lac Mégantic.
