BUENOS AIRES — Just hours before the United States, Mexico and Canada are slated to sign a landmark trade agreement between the three nations, Prime Minister Justin Trudeau confirmed he would participate in a ceremonial signing event here.

Earlier Thursday, U.S. officials were unsure if Trudeau would attend the event, which is expected to include President Donald Trump. Trump and Trudeau have a sometimes-tense relationship, though White House aides say the two leaders have mended some of frustrations stemming from June’s G-7 meeting. Trump left that summit early and later decided to withdraw his support for the joint statement signed by the participating countries.


And Canadian officials and others familiar with the event also had said Thursday night that Trudeau’s participation was in doubt, though they stressed that Canada — perhaps by way of a lower-level government official — would sign the agreement. As of Thursday night, Trump and outgoing Mexican President Enrique Peña Nieto were scheduled to participate in the Friday morning signing ceremony.

An early release of Trudeau’s public schedule at this weekend’s G-20 summit here featured 11 events Friday — none of them about the trade deal signing. But the schedule did include a gap in the morning before his first announced event at 10 a.m.

Canadian officials then confirmed Trudeau is slated to be there after all.

The potential snubbing would have come as Canada is still in negotiations with the United States about whether Trump will exempt Canada and Mexico from his tariffs on steel and aluminum as part of the trade deal. The lack of progress on the issue has infuriated the Canadians.

There's a key reason Canada wants the deal signed: It will immediately be excused from the threat of auto tariffs upon the exchange of the agreement’s side-letters.

A Canadian government spokesman said the text is now final, but there is also no deal to remove Canada and Mexico's retaliatory duties on U.S. farm and other exports. The spokesman also said the agreement will be the first trade deal in Canadian history that includes protections for gender identity and sexual orientation.

As of Thursday night, President Donald Trump and outgoing Mexican President Enrique Peña Nieto were scheduled to participate in the Friday morning signing ceremony. But officials said the format of the event could change and perhaps include lower-level officials.

The potential snub comes as Canada continues to negotiate with the United States about whether Trump will exempt Canada and Mexico from his tariffs on steel and aluminum as part of the trade deal. The lack of progress on the issue has infuriated the Canadians.

Canada’s ambassador to Washington, David MacNaughton, recently said in jest during a POLITICO interview that with steel tariffs lingering, perhaps the appropriate Canadian to sign the agreement would be a Buenos Aires embassy underling “with a bag over his head.”

But the Canadian government is worried about more than the tariffs: Next year’s election is also a concern. Trudeau is wary of being seen as kowtowing to Trump, for fear of losing votes to the left-wing New Democratic Party and jeopardizing the Liberal hold on big-city and suburban districts.

One U.S. source familiar with the late-stage discussions about Friday’s event says it’s possible there will be two events: a signing featuring ministers and a public leaders’ meeting that might — or might not — include Trudeau.

A Canadian government spokesman had no comment on the event.
