Let me pose the question in a slightly different way.
Your report highlights quite a large number of gaps between what the DFO should reasonably be expected to do and what they are able to do. I think the capability is there, but the resources have gone through ups and downs over many years. With so much not being done, and so much not known conclusively, it would appear that the risk management regime that DFO is supposed to apply is shot full of holes, which certainly must run headlong straight into the precautionary principle and that obligation.
Would you agree?
