I'll be very brief.
In Canada, which has a market-based system, decisions to pursue the construction of pipeline infrastructure are made by the companies based on the business need, but it's very clear that in order to get our oil and gas and other resources from where they are to where they're wanted, we need the infrastructure, which, in the case of oil and gas, is our pipelines. We're committed to ensuring that pipeline projects proceed in a manner that's environmentally sustainable, economically feasible, and socially beneficial.
