I will let my colleague Alex Neve complete my comments, because he will probably be able to provide more references in this regard. For my part, I know that other countries such as Great Britain have created such parliamentary committees. We all understand that Bill C-22 refers to a parliamentary committee on national security, but that kind of mechanism often reaches its limits.
National security agencies sometimes have trouble working together, and we have unfortunately seen that in the past. Organizations all have their own particular culture. That is why other countries, and even Canada, have trouble putting in place an organization that will be able to oversee all of it. There has to be a way to get beyond those cultural differences and that past in order to be able to do so.
Perhaps my colleague could provide a better answer to your question.
