After Trump left the event, he launched a scathing attack on Canada's tariffs, while Trudeau called the USA president's steel and aluminum imports tax "kind of insulting", and insisted that Canadians "will not be pushed around" when it comes to further talks.
The joint communique was published online before Trump tweeted his disapproval after comments made by Canadian Prime Minister Justin Trudeau on the new trade tariffs.
Canada's Prime Minister Justin Trudeau takes part in a news conference in Ottawa, Ontario, Canada, May 31, 2018. Addressing reporters in Singapore ahead of Trump's summit Tuesday with North Korean leader Kim Jong Un, Pompeo said he was "unconcerned" that Trump's treatment of Canada - a close ally - boded poorly for his ability to forge peace with a longtime USA adversary. In fact, completely the opposite is true, especially when we are treating our Canadian brothers and sisters like pariahs after we've had each other's backs for decades.
White House Director of Trade Policy Peter Navarro said on "Fox News Sunday" that "there's a special place in hell for any foreign leader that engages in bad faith diplomacy with President Donald J. Trump and then tries to stab him in the back on the way out the door".
Mr Trudeau did not immediately respond, but his office said on Saturday after Mr Trump withdrew support for the communique that the Prime Minister had not said anything in his closing news conference he has not said to Mr Trump before.
Saturday, Trump summit pulled the U.S. endorsement of the summit communique - a joint statement that was signed by all the other G7 participants: Canada, France, Germany, Italy, Japan and the United Kingdom.

He explicitly linked American military spending to the European Union's trade surplus with the United States, with Germany his main target.

As BuzzFeed News reports, footage from last week's G-7 summit has sparked speculation that the 46-year-old Trudeau - whose good looks are often compared to The Little Mermaid's Prince Eric - wore, erm, fake eyebrows to meet with his fellow world leaders.
"[Trump] wants to move all of that manufacturing back to the States, [but] we don't have people to actually do this work", Heyman said.
"Canadians are polite and reasonable but we will also not be pushed around", he said.
But the response by USA lawmakers, business executives and officials falls short of the concerted and effective nationwide pressure campaign Canadian officials had hoped would be launched if a major threat developed.
Sometimes described as a "mini-Obama", not least due to his omnipresent smile, Trudeau is clearly far closer in his political alignments to the US Democratic Party than Trump's Republicans.
