I'll preface my remarks by saying that this is an issue that was identified in 1987, when these sites were first identified as being severely degraded and in need of remediation. There have been, as you said, four plans—Canada-Ontario agreements—since that time. We have noted some weaknesses in previous plans. We've noted some marked improvements in the most recent plan in terms of identifying the roles and responsibilities more precisely.
One of the things that gave us some cause for concern was that whereas the government previously had targets for delisting these sites—in other words, returning them to beneficial uses and delisting them from being areas of concern—they no longer have targets for doing that. So that was an issue of concern in the most recent agreement.
