Understood, but it's just that it's not a non-disclosure agreement. It's called being read in. It is an agreement that is signed by officials when they're going to be party to highly sensitive official information or secret information.
For many of our files, the Department of National Defence requires it, even if you have a security clearance, which I do. For specific files, if you're going to be privy to sensitive information, you have to sign an agreement saying that you have been read in, you will abide by the security procedures, and you will respect the classification of information. It's very important. I should say that you are also read out at the end of that.
To answer your question, yes, I was.
