I'm referring to Mr. Mulligan and Mr. Brown who are representing the railways. I don't recall a motion of this committee inviting them as witnesses. We passed a motion inviting the minister to speak with us for an hour on the topic of rail safety—an invitation he declined. We invited the Auditor General to appear for an hour on the topic and she graciously appeared today for an hour to answer our questions.
I'm just a little bit confused about how witnesses are invited. Obviously, the gentlemen who are with us today have important information on rail safety, but if we're going to study the topic of rail safety, which I very much want to do, there are others who I believe the committee should hear from, notably rail workers, independent experts and rail communities.
As I mentioned, I put a motion on notice previously regarding a study of rail safety and I would like to bring that forward at this time.
