I think it would be something that is case-specific, so it probably would be more useful to comment on specific recommendations, but in general, where there is a safety issue that has been raised and there is an evident step forward that can be taken to rapidly address that, we do have tools to make some changes to those. We do consult with industry and with other affected parties to find out what those unintended consequences might be, as the TSB chair mentioned earlier, and we go through a process of looking at how they could be implemented and what kind of regulation you would make to do that.
In some cases, in addition to those steps, we need to do some research on what that would look like. On some of the recent recommendations on OC Transpo, for example, in terms of distracted driver guidelines, to follow up on that recommendation is going to need some research. It's going to need some collaboration with the provinces. Some of those types of things can take a little longer.
