Lashing out at the longtime USA ally and northern neighbor, President Donald Trump tweeted that Canadian Prime Minister Justin Trudeau is "dishonest & weak" and that the US was pulling back its endorsement of the G-7 summit's communique in part because of what he called Trudeau's "false statements" at a news conference.
The announcement and Trump's planned tariffs have also put him on a collision course with Trudeau, leader of another key United States ally. "He did a great disservice to the whole G7", Kudlow said.
Trump's bombshell announcement that he was backing out of the Group of Seven communique, made after he left the summit in Canada early, torpedoed what appeared to be a fragile consensus on the trade dispute between Washington and its top allies.
In her own tweet, Green Party leader Elizabeth May says Trudeau is handling what she calls Trump's outbursts and bullying as well as anyone, and that all Canadian leaders need to support the prime minister.
"Canadians are polite and reasonable but we will also not be pushed around", he said.
Canada's Prime Minister Justin Trudeau leaves a press conference at the G7 Summit in the Charlevoix town of La Malbaie, Quebec, Canada, June 9, 2018.
"[Trudeau] went out of his way to try to downplay tensions", said White House reporter Michael Shear.

In retaliation, all three allies vowed to impose retaliatory tariffs on scores of US products.
"We were very close to making a deal with Canada on NAFTA, bilaterally perhaps, and then we leave and Trudeau pulls this sophomoric, political stunt for domestic consumption".
"We have to keep a cool head now and draw the right conclusions", Maas said.
What did Trudeau say to warrant Kudlow's claims?
Trump also called for Canada to drop all trade tariffs, such as the one created to protect Canada's small dairy industry, and threatened more trade action if Canada did not acquiesce.
"Very dishonest & weak", Trump said, adding that recently imposed U.S. tariffs on imports of Canadian steel and aluminium were in response to similar measures imposed on American dairy products by Canada.
IHOP Is Changing Its Name to IHOB and Twitter Is Shook
Although the pancake giant did not say what the "b" means, it said it will announce what the "b" stands for on June 11. Some suggested the "b" could stand for breakfast, bancakes or burritos - and a few other inappropriate proposals too.
Saturday's picture was not the first awkward moment between Mr Trump and Mrs Merkel, who makes no secret of her disagreement with the American leader's approach on trade, his rejection of the deal to limit Iran's nuclear programme and his decision to take the United States out of the global Paris deal to fight climate change.
In a separate interview on CBS's "Face the Nation", Kudlow said the Trump had a "very successful, calm, friendly, respectful bilateral" with Trudeau and that the USA won't withdraw from Nafta. He also attacked Trudeau's character, calling the Liberal Party leader meek, weak and dishonest.
He said he had suggested to the other G7 leaders that all trade barriers, including tariffs and subsidies, be eliminated. "He ought to come out today and wish President Trump well in the negotiations instead of taking pot shots at him".
A German government spokesman said Sunday that despite Trump's retraction, Berlin stands by the jointly agreed G7 communique. "Americans stand with you, even if our president doesn't", he wrote.
Trump was doing Trudeau a favor by coming to Quebec for the G7 when he "had bigger things on his plate" with the North Korean summit.
Trump also targeted Trudeau on Twitter this weekend after the talks, saying Trudeau's "false statements" led him to decide not to sign the G7 communique.
