In the case of mining, I don't know for sure whether there is one internationally that could be pointed to.
What has happened is that in the past, there has been case-by-case sparring, and that has led to specific approvals, in the Canadian history for sure, for a specific mine.
Mining is regulated provincially. In Ontario we now have new standards under Ontario's Mining Act. The environmental community still wants those improved.
For example, in the Ontario context, the environmental community would still say that those need to be further improved, that they are better than they were 100 years ago, but that they are not where they want them to be ultimately.
