Blowing up the deal appears to be Trump's favored choice.
"We'll see what happens", Trump told reporters in the Oval Office after being asked whether NAFTA was dead.
This scenario carries the most risk, Barutciski said, as it would involve the USA president "recalibrating" and making a number of unilateral decisions such as imposing direct tariffs on Canadian dairy producers, Mexican trucking companies or any number of other products the US brings in via its northern or southern borders.
Trudeau, who is on his second visit to the U.S., seemed to be polite about Trump despite Canada's repeated collision with the USA due to the NAFTA negotiations. "It's possible we won't be able to make a deal and it's possible that we will", Trump said, noting the close relations between the two countries and leaders.
U.S. Commerce Secretary Wilbur Ross, one of Trump's top trade advisers, downplayed the chances that a NAFTA termination would become necessary.
"I hope the Trump Administration realizes that negotiating without foresight doesn't just adversely affect our economy, it is a return to a panicked approach to globalization and adversely affects the jobs of the 21 Century workforce that depend heavily on American ingenuity".
On the issue of taxation in the United States of 300 % of the countervailing duties and anti-dumping duty on the aircraft of the CSeries by Bombardier, the prime minister was said to have had frank discussions, but hard, with the president and expressed his disagreement.
Both Canada and the United States are in favour of making an environment agreement in the new NAFTA instead of designing a separate deal.
So the administration has been seeking to ensure that more auto production be made in America to receive NAFTA benefits, that more government contracts in the NAFTA bloc go to USA companies and that NAFTA expire unless the countries agreed every few years to extend it.
Those proposals are considered poison pills by Canada and Mexico.
In a press briefing at the Canadian embassy, Trudeau insisted that maintaining the trade deal between the United States, Canada and Mexico would "produce better outcomes for the citizens of all three countries", enabling North American businesses to compete more effectively in the global market. "The circumstances are quite unpredictable and we are ready for anything". But Congress can fight back. Under the USA proposal, America would require more to be made in the country and less sourced from other members of the block. They could also threaten to block the president's agenda unless he secures congressional approval to withdraw.
Trudeau goes to Mexico Thursday in the aftermath of a day's worth of meetings in Washington, D.C., largely focused on saving the trilateral trade pact. Some of the tariffs wouldn't be especially high.
For that reason, many agricultural lobbies and lawmakers from farm states have urged the administration to "do no harm" in the NAFTA talks.
In fact, the United States has been the biggest beneficiary of the agreement. "We need to talk about labor costs and how wages are much cheaper in Mexico".
NAFTA supporters are already rallying.
"We're here to support people before corporations - workers, and jobs in the USA that pay a living wage", said Rep. Marcy Kaptur, D-Ohio.
