I have a last question about the slide that shows the benchmark prices, WCS versus Maya. I know you are not petrochemical engineers, but what is the difference between Maya and WCS? I know they're both heavy crudes, but are they similar in consistency in every way? Do they have different effects on the infrastructure they're moving through? Does one type wear out pipeline infrastructure quicker than the other, or are they basically the same? I know Maya is already passing through the line, through the Portland-Montreal line, and through Line 9 as well sometimes. Could you address that?
