I would add to that the importance of our U.S. partners and our relations with the U.S., because a lot of this we share with respect to our interests. Of course, with that, there is the integration of those.
Thinking ahead then, although we invest in our infrastructure, sometimes we have to talk to our neighbours on the other side of the border to ensure that what we integrate, transportation strategies for example, integrate appropriately with those we're doing business with.
