Trudeau responded with a written statement, saying his comments in public and in private with Trump were "nothing he hasn't said before" and that he was "focused on everything we accomplished here at the G-7 summit".
The other leaders of G7 nations must not be afraid to reach agreements without US President Donald Trump at their upcoming summit, French President Emmanuel Macron said on Thursday, as a trade war between Washington and its allies looms.
Trump said he didn't blame the G7 leaders for "unfair" trade deals but rather their predecessors.
"Canadians, we're polite, we're reasonable, but we also will not be pushed around".
Soon after the joint statement was announced, the USA president tweeted defiantly about not allowing "other countries to impose massive tariffs and trade barriers on its on farmers, workers and companies".
As Buzzfeed's David Mack noted, Trump's sudden change just doesn't look good considering he is on his way to a historic summit with North Korea and begs the question "Why on earth should they trust the United States?"
"I have made it very clear to the President that it is not something we relish doing, but it is something that we absolutely will do", Trudeau said. Trudeau said he "accepted" the long USA explanation in the statement about how Washington did not back the Paris agreement.
Trudeau added that he had not agreed to a new North American Free Trade Agreement with a sunset clause.
He rebuked Canadian Prime Minister Justin Trudeau for being "dishonest & weak" and making "false statements".
"It's a brutal blow to a summit of significant success, both in substance and in presentation", said John Kirton, director of the University of Toronto's G-7 Research Group.
Trump's statement was made just before he left: the United States president has been at odds with the G-7 countries over mounting import duties disagreements.
Trump's early exit on Saturday also means he will be gone before allies begin closing news conferences likely to be laden with criticism of the USA stance on trade and Trump's abrupt suggestion on Friday that Russian Federation be re-admitted to the elite grouping. "And I think on trade, there is a critical path, there is a way to progress altogether", he said, speaking in English.
He said he had suggested to the other G7 leaders that all trade barriers, including tariffs and subsidies, be eliminated.
It's unclear whether Trump was joking or falsely believed Canada was responsible for burning down the official home of the U.S. President more than two centuries ago. Earlier in the day, G7 countries announced they had raised more than $3.8 billion in an effort with other countries to send the world's poorest girls to school. Trump said Friday he thinks the group will produce a joint statement.
"Take down your tariffs & barriers or we will more than match you!" Canadian officials explained that the United States and Japan did not sign on because they did not want to commit to firm targets to reduce plastics. "If we're unable to make a deal we'll terminate Nafta", Trump said Friday morning.
