Canada is a little bit unique in terms of our rail structure to start with because we do have the presence of, at best, an oligopoly; there are just two railways.
In general, the U.S. is much more competitive for rail. That’s why I indicated at the outset that we as an agency only come into play, or should only be in play, when there is some type of market failure. That's why I indicated at the outset, we only really come into play, or we should only be in play, we, as an agency, when there is have some type of market failure. We'll come in and interswitching is one type of regulation that we have at our disposal to try to address that. The other is the dispute resolution. It's a little long-winded, but when you go to a competitive market, for example like the U.S., the need and requirement, just in general and in most instances, are less.
