Thank you.
In listening to all of this today, from the hands-on, to the learned legal side of things, we hear about Kalamazoo and lot and the lessons learned. It was probably one of the worst that's ever happened in the States, as we understand.
We've been very fortunate that our pipeline industry has done their due diligence and made sure that our pipelines have been secure. What environmental precautions have been brought forward as a result of those lessons learned in Kalamazoo? How much more effective has the safety regime been on the Canadian pipelines as a result of those lessons learned?
I'll go first to Mr. Blakely, and then ask Mr. Donihee, please.
