I don't have any answer for you on the enforcement question. I don't have any experience in the United States in that regard. I'm sorry, I can't help you there.
I do have an answer for you on the lessons learned. One lesson clearly learned in Canada a long time ago, which we've put in place and has benefited us, is the ERAP lesson. I'm proud of that on a Canadian basis. In the States when they started to look at legislating security, the question came up, what goods? The answer was everything. In Canada we've already done that homework. It's already been split out as to what should be regulated in security--the ERAPs--and what are lower levels that wouldn't necessarily see a benefit from that.
So I think the lesson learned, at least in some cases, is that Canada is ahead of the game. We didn't have that struggle with a long list.
