Mr. Trump's tweets taking aim at the leader of a country that has always been a United States ally came after the President left the G7 summit in Canada to travel to Singapore ahead of a planned diplomatic meeting with North Korean Leader Kim Jong-un, CNN reported.
On Monday afternoon, the House of Commons passed a unanimous motion decrying "disparaging, ad-hominem statements" as counterproductive, while supporting Trudeau's threat last week to impose retaliatory tariffs on the US if it doesn't rollback its own fees on steel and aluminum.
May 31 - The Trump administration announces that Canada will no longer be exempt from steel and aluminum tariffs, prompting the Trudeau government to announce its own counter-measures.
"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", Navarro said in an interview on "Fox News Sunday".
White House economic adviser Larry Kudlow explained on CBS' Face the Nation that Trudeau's comments had inspired Trump's fury. Hours ago, Secretary of State Mike Pompeo held a news conference in which he said Trump is prepared to offer North Korea unprecedented security assurances, although he did not specify what these guarantees would be.
"Kim must not see American weakness", Kudlow said.
Trudeau said he told Trump directly that Canada "particularly did not take lightly the fact that [the tariffs were] based on a national security reason".
But Trudeau didn't say anything after Trump left the G7 that he hadn't signaled before - namely, that Canada finds Trump's steel and aluminum tariffs insulting and will retaliate.
The motion in parliament, introduced by the opposition New Democrats, rejected "disparaging ad hominem statements by USA officials which do a disservice to bilateral relations".
Trump was infuriated by the news conference and abruptly withdrew US support for the summit's relatively anodine closing statement, a boilerplate invocation of the importance of multilateral trade rules.
Since Trump's election in 2016, Trudeau has tried to take a conciliatory approach to the populist Republican president and has been careful never to run him down in public.
After Mr Trump had left the summit in Quebec he rounded on Justin Trudeau personally via Twitter, suggesting the Canadian prime minister was "very dishonest and weak" and "acts hurt when called out".
Mr. Trump's actions led to an extraordinary juxtaposition: an abrupt public feud and deterioration of ties between the USA and Canada at the same moment as warm words and a detente between the US and North Korea.

Only United States can get all the perks and profits? Its tariff on milk of 270 percent, highlighted by Trump officials, is stupid and indefensible.
- En route to Singapore, Trump launches a ferocious attack against Trudeau on Twitter, calling his behaviour during G7 meetings "meek and mild" and accusing him of making "false statements" at his press conference.
He also asked why he should allow countries to amass "Massive Trade Surpluses, as they have for decades, while our Farmers, Workers & Taxpayers have such a big and unfair price to pay?"
The President insists he has slapped the levies on to hit back at charges imposed by other countries and has accused his allies of trying to milk the Us's economy.
