Mr. Chairman, I will talk generally about rule harmonization and the challenges we have overall.
In all domains—it's not just transportation of dangerous goods by rail; it's also in the marine world and in the aviation world—we try to have the highest possible level of standards. In both the marine and aviation domains, we're dealing with international organizations, the International Maritime Organization and the ICAO, the latter located in Montreal. With these organizations, we have the chance to develop international standards that are adopted across numerous nations. The IMO has 169 members.
When it comes to TDG, transportation of dangerous goods, and rail, we are in the context of North American standards, and it requires a significant amount of dialogue with the U.S., in particular. On a continuous basis, we try to influence the U.S. regulators, but bear in mind that we're dealing with quite a giant and we need significant support at the highest level. The RCC does that particular work for us.
Working with our counterparts on both sides of the border on specific items of harmonization helps us level the types of requirements that we get and also looks at best practices on both sides of the border. They have been fairly beneficial so far, and we'd like to continue with these aspects.
