I'll kick it off. Thank you for the question. It's a great one.
I'll tackle the competitiveness with the U.S. first. That is an important point. We can't forget about our neighbours to the south. As I mentioned in my opening remarks about cargo being king, once cargo finds another routing it won't come back, no matter what you do and no matter what incentives you apply. The switching costs in shipping are so high that once an alternative route is found, a port won't get it back. There may be some small exceptions. There's always the worry of the thin edge of the wedge. If the door is open a bit and cargo finds its way into Canada via a U.S. port, that would probably expand and continue.
U.S. ports are at capacity, or many of them are, so there could be some constraints there that may not make this practical. Something that we as Canadians have to be very aware of is keeping the whole system competitive. That's in trucking, rail, ports and labour. It all works together.
