I haven't really turned my mind to this in any depth before. As you're aware, there are obviously re-evaluation requirements. As new information comes to light from other jurisdictions or from within Canada, the act happily does provide mechanisms to ensure that as we learn more, as scientific knowledge increases, we have the ability to go back and review again. A special review mechanism is probably the most public-friendly version of all of those mechanisms, because the public has the right to ask for it.
