Let me try to answer you. You've asked two or three questions there.
Let me first clarify the role of the CTA. The CTA is essentially the regulator under the Canada Transportation Act, which is essentially the act that regulates our commercial relationships and also areas such as accessibility, disabled accessibility, and those sorts of things. There's a separate piece of legislation that regulates us for safety, which is called the Railway Safety Act. It is operated in an entirely different context. The CTA does not involve itself, in normal circumstances, in safety regulatory matters.
But how does the CTA enforce its rulings? It has the legislated power to do so and can order us and has ordered us in the past to do a number of things. And that has strength. They also have a number of sanctions they can impose in terms of the way in which licences are issued in the country and those sorts of things. So they have a number of remedies, and frankly, you would defy a CTA order, if you were a company operating in the transportation system in Canada, at your peril. They have significant powers.
