Let me say that we are tracking it very closely. I'll unpack a bit of what you just said. The Mexican electoral calendar is the following. The actual election is in July 2018, but the informal electioneering has already begun, as you noted. There are various theories as to what the key issues will be. It will begin in earnest as we get into December 2017 or January 2018. I believe there is a law or at least a protocol in Mexico that anybody running for president has to step out of current functions six months before the election. That's how that timeline is driven. Then there is a very long period between election day and the inauguration. There is a very long handover period that lasts from July, in this case July 2018, through to November. The Mexican electoral calendar will intersect with the NAFTA renegotiation calendar, or at least the projected calendar, and I might turn to Martin in a moment to speak to the NAFTA calendar.
The other thing I would say, on your question about a trilateral or bilateral negotiation—again, Martin can fill in the details—is that Canada's position is that we would like a trilateral negotiation. That is Mexico's position as well. But even in the existing NAFTA, which is a trilateral agreement, there are various elements that are essentially bilateral in nature. This question continues to be presented in the media and elsewhere as a binary question—it's either bilateral or trilateral—but you can have a trilateral negotiation that ends up with elements that are more applicable to two of the parties than to all three parties.
