I agree with Kapil that to finish it in less than a couple of months would be aggressive and ambitious at the same time. I think a more substantive review is due. I was around for the CEPA 1999 review. That one took a considerable amount of time, and in my humble opinion, the changes were not adequate to address the needs. So I would encourage you to take that into consideration.
On the issue of which parts of CEPA need more attention, I think Kapil is quite right in that the changes to one section will inadvertently require reviews of other sections. That said, I think increased attention to the pollution prevention clauses and implementation of regulatory backstops would go a huge way to improving the way that CEPA, as it's currently written, is implemented. Similarly, provisions to make stronger ties to international agreements would help consolidate the Government of Canada's approach to toxics management, both domestically and internationally, with our allies.
