I think the example of the Barrick mine at Porgera in Papua New Guinea is very relevant to this discussion, because it is actually an example of a situation in which there is no real regulatory framework being applied, given the failure by the government of Papua New Guinea to apply its own laws and regulations to the situation.
So what you have, essentially, is a company that says it is applying all of the standards that are incorporated in Bill C-300. Barrick is not yet a member of the voluntary principles on security and human rights, but it says that it applies them in all of its operations. It says that it has a zero tolerance policy for all of the abuses that our research and Harvard and NYU research uncovered there. They say they're doing everything they can think of to combat these abuses, but the fact is that they haven't managed to go as far as they need to go.
I think their failure to do so really does expose the limits of a purely voluntary framework. There has to be some kind of binding regulation to go along with whatever voluntary measures businesses choose to participate in. Even if those voluntary measures are very useful and ought to be encouraged, they're not an adequate replacement for government regulation in and of themselves.
