I think it's important to prevent online the same things that are illegal and objectionable offline. We need to ensure that we have strong measures online to prevent piracy, child exploitation imagery, and hate speech and defamation, the things that in Canadian society generally are inappropriate or illegal content. We need to find legal mechanisms to ensure that we address those issues online, too.
The precise legal mechanisms will vary depending on the issue and that's a much longer discussion. But at the level of general principle, I don't think the Internet should be a free-for-all.
