The American approach has been to have legislation specifically addressing children's privacy. The Canadian approach has been to deal with it under PIPEDA and to recognize that children may be a special case, so as a matter of interpretation, we take into account the fact that a website might be targeting children.
I guess the issue is, do we want to have something very specific in the legislation that makes it clear that when you're dealing with children, the rules are different or the rules are stricter? I see some merit in that: in being very explicit and up front that the rules for consent may be expressly different when you're dealing with children.
In that a lot of websites that target children are based in the United States, where they actually have to comply with the American laws, we've benefited to some extent. In Canada, we're simply not clear and explicit about the steps that have to be taken to protect children's privacy.
