That's an excellent question, because that has actually been our challenge with different users being at various different stages in terms of their adaptation to new technology. We are in the situation now, and will continue to be in the situation for a while, of having to manage more than one system through the transition.
Our challenge, as I think the committee knows and as the Auditor General noted, is we have had significant difficulty being able to discontinue some types of services and some types of aids that in our view, quite frankly, no longer contribute at all to safe navigation, issues of foghorns, issues of staffed lighthouses or things that this committee is very well aware would fall into that category.
What we have done is to launch a program that we're calling aids to navigation for the 21st century. We announced that in January. A part of that program will be to develop a vision for electronic navigation. We have a pilot under way now in the St. Lawrence on that issue, but we hope through that to develop a longer-term vision and to engage the various users of our services in it.
