According to Trudeau, he told the president that Canadians may be polite and reasonable but they will not be pushed around and that his nation doesn't "relish" putting tariffs on US goods and services but is willing to do so.
Kudlow was particularly offended that Trudeau would say this ahead of Trump's North Korean summit. He also attacked Trudeau's character, calling the Liberal Party leader meek, weak and dishonest.
EU nations are set to impose counter-measures on U.S. goods in response to tariffs on European steal and aluminium, but Mrs May cautioned against tit-for-tat retaliation that might lead to a trade war.
While foreign policy issues such as North Korea do not usually have much bearing on the polls, Mr Trump's outburst against Nato allies, the European Union and Canada appeared aimed at striking a chord with voters who support his America First agenda.
"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", Trump trade adviser Peter Navarro said in an interview nationally broadcast Sunday in the United States.
"On his comments, I'm going to stay focused on defending jobs for Canadians and supporting Canadian interests", Trudeau said before walking away from reporters.
The U.S condemnation stems from Trudeau's assertion that Canadians "are polite, we're reasonable, but we also will not be pushed around", a point he had made several times before.
Mr Trudeau and the European Union have vowed to take retaliatory action next month over USA tariffs on steel and aluminium.

French President Emmanuel Macron's office reacted Sunday by saying that "international cooperation can not be dictated by fits of anger and throwaway remarks".
When Trump left Quebec, it was thought that a compromise had been reached, despite the tension and the determination of European leaders Macron and Chancellor Angela Merkel of Germany to push back against the U.S. president's protectionist policies.
According to White House economic advisor Larry Kudlow, Trump's preference now is to actually negotiate with Mexico and Canada separately.
Last month, US Trade Representative Robert Lighthizer said the current NAFTA is a seriously flawed trade deal, and the Trump Administration is committed to getting the best possible trade agreement for all Americans.
"Navarro himself crossed a line, basically telling a leader of a foreign nation that he needs to go to hell.I don't care how mad, how angry you are, you don't treat the head of state of another country like that unless you are getting ready for a military engagement of some kind".
"Congressmen, politicians, people, you know realizing this is a bad thing-maybe that message will get to Donald Trump and we can hope he'll listen, although one might not be very confident that he'll listen to reason".
Meanwhile, the Canadian province of Quebec has offered $C100 million ($A101 million) in loans and guarantees for steel and aluminium companies hit by the USA tariffs.
While trade is expected to dominate, Trudeau also wants to focus on gender equality and climate change.
