It's increasingly difficult to figure out where CEPA begins and ends and where government action begins and ends.
The act itself is quite a fine piece of legislation. That reminds me of the story about your kid has great manners; they've never been used. It's a good piece of legislation. We just haven't actually used it very much to figure out where it can be seen to be effective and where really the challenges are. The precautionary principle is in the preamble. There's no reason why it shouldn't filter through the kinds of actions that are enabled through CEPA.
In one way my response is that I don't really have any criticism of the precautionary principle or the act, but I have a lot of criticism around how it has or has not been implemented. Reading the act, one would assume we would have all kinds of great action in Canada, but we don't.
