On the second question, clause 3, we have to remember there are two different obligations under this act. Under clause 3, they're required to report to a designated agency, and under clause 4 it's a requirement to notify the proper police authorities. If they have reason to believe under clause 4, they must preserve the evidence under clause 5.
Under clause 3, you're worried about the standard of “may be available”. When developing the legislation, two principles that the minister articulated were kept in mind: that the legislation shouldn't contribute to the further dissemination of child pornography, nor should it contribute to the creation of further consumers of child pornography. So creating a lower threshold may be available.
This is a standard that the ISP will employ when receiving a tip. If they receive an e-mail from a subscriber that says he or she found child pornography at a website, that's the standard that meets “may be available”. We don't want them to require their personnel to go to the website and confirm there's child pornography; we simply want them to advance that tip to the designated agency to triage and send it on to police if it turns out to be child pornography.
The standard really is for their own recognition of the credibility of the tip and whether it constitutes something that fits under this legislation.
