It can be difficult to speak in hypotheticals.
How I would respond is to say that, if Environment Canada or Health Canada is made aware of a particular case, and DND or any custodian is in need of some supporting detailed analysis, that is possible for us to do. We can review the conclusions.
I think we would discuss it with DND or any given custodian and then assess the science, if that was required. I would point to the accountabilities of each custodian, which we've mentioned, and also to the professional obligations of the staff and the consultants who work with them to meet their ethical and professional requirements.
