I'll talk for Suncor.
I would say first of all that we do a lot value-added, so we do run upgraders. As I mentioned at the start of my comments, we are in the refining business, so we like to add value wherever we can within Canada. One example where we'll be able to improve that I think is the reversal of Line 9 and being able to take crude oil into our Montreal refinery. We see that as a positive step.
It is a complicated calculation in terms of market balance and where existing refinery operations exist and where markets exist. We'll do it where we can, but I don't think it's a one-size-fits-all blanket comment that it can be done everywhere.
