Okay, thank you.
Continuing on the topic of pipelines, I have seen a chart from Transport Canada that's in the public domain and actually lists the number of pipeline incidents that have occurred in Canada over the past 10 years or so. It's quite dramatic to see the number rise steadily from 2001 to 2011. I'm wondering if you can comment on what's happening in a chart like that. Why are we seeing so many more?
