Could I just add one sentence to that?
Marie-Hélène's point is very well taken as it relates to the differences between the types of ethanol that are out there. Right now Canada imports one billion litres of American ethanol. We do that because it's very inexpensive. By removing the excise tax on the cellulosic fuel, we'll be shrinking the differences between that American imported product, which is coming all the way from Iowa, Kansas, or further, and replacing it with a homegrown product.
Very small incremental steps can make a difference, but when you're buying at 10 million litres at a time, that will make a very big difference.
