Following the 2018 G7 summit in Charlevoix, Quebec, a significant diplomatic disagreement erupted between Prime Minister Justin Trudeau and President Donald Trump regarding trade and personal conduct.

Although Trump initially supported the summit's end-of-summit communiqué, he withdrew his support after taking offense at remarks Trudeau made during a post-summit news conference. Specifically, Trudeau stated that Canada would reluctantly impose counter-tariffs on the United States if necessary, asserting that while Canadians are "polite" and "reasonable," they "will not be pushed around."12

In response, Trump took to Twitter to characterize Trudeau as "dishonest & weak" and accused him of making false statements. Additionally, Trump’s economic adviser, Larry Kudlow, labeled Trudeau a "backstabber." Canadian officials maintained that Trudeau’s comments were consistent with what he had previously expressed to Trump in person and in public. The conflict concluded with the Canadian House of Commons unanimously passing a motion to condemn the U.S. president's personal attacks on the prime minister.12
