"I think that we've had a massive effort on tax reform in the United States which has had a incredible impact on the USA economy", Mnuchin said.
Trudeau added that he does not know what Trump wants Canada to do in order to remove the tariffs, because the US actually exports more steel to Canada than Canada sends to the USA, and when it comes to oversupply from China, Canada is on the same page as Trump.
Kudlow said steel and aluminum tariffs on USA allies "may go on for a while" or "they may not", because the matter is subject to negotiation.
The U.S., Canada and Mexico have been holding talks to renegotiate the deal.
Canadian Prime Minister Justin Trudeau hit back at the recent tariffs implemented by President Donald Trump against Canada, telling NBC's Chuck Todd it was "insulting" that the tariffs were imposed under the guise of protecting United States national security and that Canada is not "going to be pushed around".More news: 30-year-old New York man evicted by parents leaves their home
European Union Trade Commissioner Cecelia Malmstrom said Trump's steel tariffs have nothing to do with national security and called them "pure protectionism". "As a fine friend and ally of the United States, nobody denies that".
Speaking on "Fox News Sunday", Larry Kudlow said that the Trump administration's confrontation with Canada is a "family quarrel" that can still be resolved through negotiations.
The US tariffs are "absurd", as Canadian metal sales are no security risk to the US and the measures would destroy jobs on both sides of the border, Morneau has said previously.
The protectionist actions by the Trump administration seem to have changed that relationship, but U.S. Treasury Secretary Steven Mnuchin maintains that the U.S.is committed to its role, telling reporters after the meeting, "I don't think in any way the U.S.is abandoning its leadership in the global economy". It also requested a review of the U.S. measures under the North American Free Trade Agreement Chapter 20 trade dispute mechanism.
Allies including Canada and the European Union are threatening retaliatory tariffs. "They're saying something that we believe is patently untrue".
Trump and other G7 leaders meet next weekend in Quebec.
Finance Minister Bill Morneau, who chaired the Whistler meetings, said even though the group found common ground on many subjects, G7 members are now forced to do whatever they can to convince Trump to move back from the tariffs.More news: Roseanne Wanted TV Show To Be Canceled, Ex-Husband Says
Mr Le Maire said it is up to the United States to take action to rebuild confidence among G7 members and to avoid any escalation during the leaders' summit next week.
His opinion was echoed by French Finance Minister Bruno Le Maire who said that Mnuchin was alone on the tariff issue, with the group becoming a "G6 plus one" as the other six G7 members had expressed "total incomprehension" over Washington's move.
The tariffs are also unlikely to force the Mexican government's hand, especially given current electoral dynamics.
Canada announced plans to slap tariffs on $12.8 billion worth of USA products, ranging from steel to yogurt.
Trump also said in a separate tweet that "The United States must, at long last, be treated fairly on Trade".
