First, what are we doing on the risk assessment side? There are 800,00 points of call, and these points of call are organized around 6,000 different routes, so there are sometimes many hundreds of points of call in a single route. To assess which point of call has a highway traffic safety problem is a huge undertaking, because you have to go out to all of those routes and have a look, site by site.
That's what we're doing. We've asked the rural officers of our company and the local officers of our company--officials of our company--to do that for us, and the National Research Council study at least gave us some criteria that we could use to make that assessment.
We are also relying, to get this done as quickly as we possibly can, on engineering maintenance companies that work with us throughout the country on maintaining our facilities, because they have engineering capability. We're relying on these companies to give us extra arms and legs, to go and look and try to assess where we might have an issue so we can be a little bit more proactive and say to Canadians who might be affected, “We're worried and we don't want you to see a disruption in service without notice.” So we're doing that.
