Thank you.
Thank you to the presenters for your very interesting viewpoints.
I am going to try to ask three quick questions, first to Mr. Marshall; he's been let off the hook so far.
You said that the federal jurisdiction is limited. We know that energy is mostly provincially regulated, and that makes it difficult to come up with national strategies. I just wondered what problems this creates for you as an interprovincial system operator. What kinds of problems do you see all these different regulations causing?
I guess what I'm thinking of is if we're going to move to an east-west grid, what needs to change? What steps need to take place in order to move to the development of an east-west grid?
