No, there hasn't.
As far as we know, the federal government, or rather national defence, hasn't done any decontamination work.
As I explained earlier, we're the ones responsible for overseeing the decontamination of a tiny part of the site so we can build our Urbanova interchange. We would be happy to partner. If we could get the site decontaminated, that would also create a number of opportunities for things like conservation, housing, economic development and businesses.
