I think the government has been very clear in its commitment to addressing those types of situations. It has the federal contaminated sites action plan, but that's for legacy government properties.
For those properties not owned by government, there is something called the shared responsibility framework that's in place. This is a vehicle through which the government can contribute to the addressing of contaminated sites when there were federal activities that led to that contamination.
For example, Defence has at the present time three shared responsibility framework agreements in place. We're negotiating a fourth in order to do exactly that: to be able to contribute to the cleanup of contamination off federal property.
