Thank you, Ms. Fox. It's good to see you back at the committee.
I'd like to pick up on the earlier remarks of my colleague, Mr. Barsalou-Duval, about safety management systems. When I looked at the TSB's watch-list and the concerns the TSB has had with it over time, which it hopes to see remedied, I was surprised to learn that safety management systems have been on the watch-list since it was created.
Could you speak to why these safety management systems have remained on the watch-list for so long—over a decade—and why Transport Canada hasn't been able to do enough to meet your concerns and address the things you're raising when it comes to these vital components of railway safety?
