In the next few weeks and months there will be time for a careful review of the new NAFTA — the United States-Mexico-Canada Agreement (USMCA) — that was posted to the website of the United States Trade Representative in draft form on October 1. Now, in the immediate aftermath of the harrowing negotiations of the past 14 months, it is easier to assess the larger importance of this agreement for US-Canada relations.

Veteran trade negotiators will tell you that tough talk and theatrics are to be expected in an important negotiation. Each side attempts to pressure the other, politically and psychologically, with threats and red lines.

The USMCA negotiation, however, was unusual in several ways.

Typically, leaders express confidence in an eventual agreement, and praise the relationship in broad terms. Presidents and prime ministers are the “good cops” so that the negotiators can play the bad cops. In these talks, however, US President Donald Trump played the bad cop, too, and made a convincing show of being angry with Canada and prepared to leave Canada without an agreement at all, and to withdraw from NAFTA as well.

Normally, interested citizens read a bit about the talks as they proceed, but must wait until a deal is reached to have an idea of what was agreed. Businesses and others directly affected work more closely with the governments and know a bit more. This time, social media made detailed arguments and analysis available to anyone, any time (though governments still remained quite guarded with negotiation details). We had Trump tweets on an almost daily basis that were cause for speculation and anxiety about what might happen next.

Since 1945, the United States has advanced principled arguments on the merits of liberalizing trade, while Canada and Mexico more often sought to protect their smaller industries and economies from competitive US firms. Now, it was Canada reciting the virtues of free trade and the United States proposing managed trade and punitive tariffs in the name of national security.

Historically, Washington has devoted attention to rivals and enemies, and for the most part ignored Canada. To manage bilateral relations with limited and sporadic US engagement, the two countries have structured bilateral relations with institutions, from the International Joint Commission to NORAD and NAFTA. Each institution is established by a political agreement on how to manage a problem or issue. The institution is then operated by public service professionals who develop solid working relationships with counterparts. This keeps important areas of the relationship on track without needing to get the US president and Congress directly involved (which works out well, since it is difficult to get either to focus on Canada, unfortunately).
