I'm afraid I don't have any insight into the specific example you've cited. I would say, though, that it's important to note that new projects, be they pipelines or other facilities, tend to be very long-lead, high-capital investments, and for a company such as Suncor to justify making that capital investment, we are trying to get as much fiscal and cost certainty as we possibly can. They're very long timelines.
When I say very long, we're talking 10-years plus, perhaps, in terms of the conception of an idea through to executing it on the ground, and there are examples of things taking longer than that. When we talk about certainty, we're talking about as much confidence as we can possibly get in justifying capital investment because of the long lead times and because of the high capital involved.
