I'm going to switch gears, because this is a discussion and a reference to the study on rail safety. I'd like a couple of people on the panel, if not everyone, to comment on this. When we talk about rail safety, one thing is that we've seen a reduction in accidents in the past few years, with less crude oil being shipped by rail than by pipeline. Pipelines are a safer way to ship natural gas and crude oil. We saw what happened in Lac-Mégantic.
What are your comments about the appropriateness or safety of pipelines versus that of shipping by rail?
