"That's going to cost a lot of money for the people of Canada; he learned", Trump said wagging his finger.
Trump also called Trudeau "very weak and dishonest" following the summit.
Hours after Mr Trump withdrew his support for the joint statement and attacked Mr Trudeau, Mr Kudlow and trade adviser Peter Navarro drove the message home on Sunday morning news shows in an extraordinary assault on a close United States ally and neighbour.
"The European Union will continue to stand up for an worldwide, rules-based, multilateral system".
President Donald Trump's trade adviser says: "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".
All lawmakers gave a standing ovation for the government's response to the Trump administration's verbal attacks on Trudeau.
Trump said he chose to back out of the G7 communique after watching Trudeau's closing summit news conference, at which he warned that Canada would not be pushed around on tariffs - a point the Canadian prime minister had made several times before.

But then Trump pulled out of a joint statement while citing "false statements" by Canada's prime minister, Justin Trudeau.

The motion in parliament, introduced by the opposition New Democrats, rejected "disparaging ad hominem statements by U.S. officials which do a disservice to bilateral relations".
Trudeau, on the June 3 episode of NBC's "Meet the Press", uses stronger words to characterize Trump's tariffs - "The idea that Canadian steel that's in military vehicles in the United States, that makes your fighter jets is somehow now a threat ... the idea that we are somehow a national security threat to the United States is quite frankly insulting and unacceptable".
Before leaving for Singapore, Mr. Trump had delivered a stark warning to America's trading partners not to counter his decision to impose tariffs on steel and aluminum imports.
Trudeau, in Quebec City for bilateral meetings with non-G7 leaders after the summit, did not comment as he arrived.
