I'd be remiss not to make one important comment.
Mr. Watson had a question about how we could improve our SMS. One of the areas that we're seized with is expanding and collaborating and partnering with industry, with pipelines to improve those response times, assets resources to reduce the response times. The second point we're seized with is risk mitigation and the closing of crossings. We have a very problematic situation in Canada where Transport Canada's objective is to close crossings. However, CTA opens crossings, so Transport Canada may close, for instance, three in a year, and CTA, without collaboration, without any due process, may open six.
Every time you have a crossing, you have an opportunity for an uncontrolled situation to occur. You have an opportunity for a truck, for instance, to impale the side of a train that may be carrying these very hazardous materials, so it's in the Canadian public's best interest and safety's interest to eliminate as many unnecessary crossings as possible and to strictly control the opening of any new crossings.
