Thank you for the question. I think it's an important question. I don't know if I have an answer for you.
Our colleagues at Natural Resources Canada are the lead for pipelines and oil and gas policy. The role of Transport Canada as the safety and security regulator touches air, marine, road and rail, so we're focused on the safety and security regulatory regimes for those modes.
It's an important question. I think it will have to be directed to Natural Resources Canada, or we can take it back to see what information we can get in terms of the analysis you're looking for.
