A little bit of discussion has taken place with respect to the precautionary principle, but I was interested to get Ms. Collins' take on it. You mentioned it in your opening remarks. Just for reference, the precautionary principle, as defined by the Canadian Environmental Law Association, is a duty to prevent harm when it is within our power to do so, even when all evidence is not in. Can you explain what currently happens without that principle, the way the legislation is currently set up?
