That's a good point.
When I set out to prepare some remarks, I went on the Internet. I looked at material available from the federal government. I even looked at Wikipedia, things like that. Those were the sources I used.
I probably missed useful sources. I even looked at information from other countries like the United States and some others, Oceania and so on. I didn't find a tremendous amount of detail available but I thought I had enough to at least craft a position.
