I think you've put your finger on a significant problem, not only for the geological survey but for most of the scientific components of the government.
As you know, there's this demographic bulge moving through the public service and society generally, and we are in fact worried about what will happen over the course of the next couple of years when people start retiring.
We're trying to develop a program to deal with these issues. NRCan, for example, has what's called a scientist emeritus program in which we have a couple of scientists who are over 80 years of age. They stay on after their retirement and continue to work in return for an office, a computer, and a lab.
That's one way we're trying to deal with keeping people on who have a lot of knowledge, but we're going to have to come up with other devices, as is the public service generally, because at some point we really are going to face a significant problem with retirements.
In terms of more detailed programs, I apologize, I just don't have it on the top of my head. We'd be more than happy to make other officials available if you'd like a more detailed briefing.
