Okay. If you'll permit, I will answer in French on that.
First, it's important to understand that, before a website can be blocked, the person responsible for it will receive a detailed notice. They will then have 20 days to decide whether or not to comply with the law. After that, the case will be referred to federal court, which will deliberate to decide whether we've really reached the stage where the site needs to be blocked. I want to say this because it's a method that is in keeping with Canadian legal standards, which protect those whom we want to punish by giving them the recourse to speak in court and defend themselves.
If, after all that, the pornographic site is deemed not to be taking action, the question of blocking arises. When an ISP is told that it must block a site, it can do so. If a website contains both pornographic and non-pornographic material, once you block it, you're blocking more than just the pornographic content. In this case, the reason is simple: it's up to the site to decide whether or not it complies with the law. Let's take the analogy of a bar. If a bar lets minors in and lets them drink alcohol, the bar will eventually lose its liquor license, preventing it from serving alcohol not only to minors, but also to adults.
