Andres Manuel Lopez Obrador is to be sworn into office Saturday as Mexico's president.
"Donald, it is all the more reason we need to keep working to remove the steel and aluminum tariffs between our countries", Trudeau said.
But while Trump proudly refers to the USMCA - a title that again puts the United States in the leading position - Trudeau pointedly called the deal being signed the "new North American Free Trade Agreement" and the "modernising NAFTA".
Trudeau pressed for a resolution to the tariff spat. But he attended and used his remarks to declare the tariffs a major obstacle to their economies.
"It hasn't been a great deal for Canada", he said.
The leaders of the United States, Mexico and Canada on Friday signed a huge regional trade deal to replace the old NAFTA, denounced by President Donald Trump as a killer of U.S. jobs.
"Modern, free and fair trade policies are critical to the success of the American aerospace and defense sector".

It will offer the Star Wars and Marvel movies along with Pixar films and a variety of animated series. No, it has been your week, month and year because Friends is not leaving Netflix UK & Ireland.
Vows to scrap NAFTA and replace it with a better deal also were staples of Trump's campaign rallies across the industrial Midwest in 2016. The trade agreement still has to be approved by each nation's legislatures.
But the path to Friday's signing has been bruising, and those sore spots will be impossible to ignore when the three countries' leaders gather to talk trade for the first time since 13 months of talks culminated in an 11th-hour agreement late in September. That could prove a hard task in the United States, especially now that Democrats - instead of Trump's Republicans - will control the House come January. Already Democrats and their allies in the labour movement are demanding changes to the agreement.
"There's still a lot of work to do on this deal before we hit the finish line", said Daniel Ujczo, an worldwide trade attorney in Ohio.
Trump spent more than a year pushing the leaders of Canada and Mexico into agreeing to a rewrite of North American trade rules.
The pact will lock in USA market access to Canada and Mexico, expand American exports and includes new measures to ensure fair competition, explained Trump as he stood alongside Canadian Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto. He says the parties have "taken a lot of barbs and a little abuse" during the renegotiation.
"It is really an incredible way to end a presidency", Trump said to Pena Nieto, promoting applause from the Mexican officials in the audience. It's the highest honor America's southern neighbor gives to foreigners.
Canada is confident it will win legal challenges to American steel and aluminum tariffs that remain despite the new NAFTA deal, Foreign Affairs Minister Chrystia Freeland said Friday in Buenos Aires following a high-profile signing ceremony for the trade treaty.

Macri is hosting the summit as he struggles with problems at home.
Trump and Macri enjoy a personal relationship dating back to their days as businessman. A senior White House official said Trump and bin Salman exchanged pleasantries during a subsequent leaders' session. Cohen admitted in federal court Thursday that he lied to Congress about a Trump project proposal in Moscow. The prime minister refused to call this the USMCA, as President Trump has called it. "Lightly looked at doing a building somewhere in Russian Federation", he tweeted.
Trump barreled into the two-day meeting by announcing via Twitter that he was canceling on Putin over Russia's seizure of Ukrainian vessels.
It also underscores Trump's turn away from the global trade deals his predecessors supported in favor of regional or even one-on-one agreements.
