Thank you, Madam Chair.
And thanks to our witnesses, especially those from British Columbia, because I know how early it is out there.
I'll start with you, Ms. Lui. You are aware, of course, that both the Trans Mountain line and Line 3 are following existing corridors, so it's not as though we're blazing a new trail through the wilderness with them.
I'm wondering if your group has any background information on how the existing pipelines have performed in those two places with respect to spills, accidents, etc. If you don't, that's fine.
