Just a very quick follow-up.
I don't have the expertise of some people at the table, such as Mr. Bevington and others have expressed, or a local community affected, but if it's a technical change I would have thought that rather than a marketplace condition--because you are the sole provider of service--if they're going to land there, they're going to use your services, such as they are. Who has the competence to evaluate those technological advancements so that we can believe this advancement can be relied on because you took up the business at a certain price, at a certain cost, and so on?
I think everybody wants to understand what's at work here, and if there are technological advancements that make things safe. If these changes are just transitions, we should understand and then approve or let Transport Canada approve. Who can tell us that technology does what you say it does, aside from the practice? I don't want to be crude about it, but you wouldn't want to learn in practice whether it works. It must be in place elsewhere; there must be bodies, international bodies perhaps, that validate this technology.
