I think for the space that these questions are in now, it will be good to hear from DND about that. We're probably into some occupational health and safety as well as some types of issues that may be in more in a uniquely defence space, so I will suggest that.
In terms of the process for identifying chemicals of concern—and I may refer this question to Greg in a moment—there is the chemicals management plan that the federal government has. Health Canada and Environment Canada co-lead that. It is not my particular area of focus, but it is a long-standing program that's been working through the many industrial chemicals that have been developed over the last 100 years and identifying and learning about those so as to understand the risks to human health and the environment.
