That's an issue that has been addressed by the International Holocaust Remembrance Alliance. I'm part of the Canadian delegation to that alliance, representing B'nai Brith. I'm on the access to archives project. We've done a lot of work in that area. There are some very elaborate and specific definitions. Because Canada is a member of the alliance, they normally comply with what that alliance has recommended.
The answer to your question is there. It's posted. It's on the Internet. It's detailed. The government, I would say, should just adopt it.
