"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.
Canada, Mexico and the European Union were among the partners to who he gave momentary relief, but the administration of the Republican president announced this week that from last Friday, they would also be subject to new tariffs, of 25 percent on steel and 10 percent on aluminum.
On Sunday, during an interview with Fox News, White House economic adviser Larry Kudlow responded to Trudeau's comments saying that he didn't think these tariffs would impact the US "friendship and longstanding alliance with Canada". Mexico complained the tariffs will "distort worldwide trade" and said it would penalize US imports including pork, apples, grapes, cheeses and flat steel.
"The fact that the president has moved forward with these tariffs is not just going to hurt Canadian jobs, it's going to hurt U.S.jobs as well and neither of those things is something Canada wants to see", Trudeau said.
The dragging on of the NAFTA talks was a key reason behind the USA move to target Canada and Mexico, but given the importance of that trade agreement to the continent's economy, neither US neighbour was deterred.
"One of the things that I have to admit Im having a lot of trouble getting around is the idea that this entire thing is coming about because the president and the administration have decided that Canada and Canadian steel and aluminum is a national security threat to the United States", he said.
Mr Trump has said the tariffs are needed to protect U.S. steel and aluminium industries vital to the nation's security. The group includes Canada, France, Italy, Germany, the United Kingdom, Japan and the United States. "To say that it is an attack on Canada is not right".
Trudeau said the reciprocal tariffs would hurt both United States and Canadian workers and consumers.
Canada's expressions of disappointment comes as China warned that any trade dispute deals reached at talks in Beijing "will not take effect" if Trump's threatened tariff hike on Chinese goods goes ahead.
The tariffs are also imposed on other allies like Mexico and the European Union, both of which have also hit back with retaliatory tariffs.
"The national security issue is a flood of imports from 20 countries that are putting our aluminum and steel industries out of business--the national security interest.is us defending ourselves against that flood of imports, so those industries can survive", Navarro said.
"He's anxious about trade surpluses, trade deficits around the world".
Trudeau, who took office in 2015, is expected to press his case directly with Trump next weekend when Canada hosts the annual Group of Seven summit, which brings together leaders of the world's largest economies, in Quebec.
Trudeau said the main goal for the meeting was to discuss how trade can ensure inclusion and growth for everyone, but said all the G7 leaders are concerned with Trump's idea that trade is a war that must have winners and losers.
"On trade, this is a G6 plus one", Mr Le Maire said after stepping outside briefly from the talks.
Mr Le Maire said it is up to the U.S. to take action to rebuild confidence among G7 members and to avoid any escalation during the leaders' summit next week. Trudeau said Thursday that the process imploded after Vice President Pence demanded that a renewed deal expire in five years.
French Finance Minister Bruno Le Maire said the United States has only a few days to avoid sparking a trade war with its allies and it was up to Washington to make a move to de-escalate the tensions. "Do Timber & Lumber in USA?" But a Business Insider analysis found that the Canadian tariffs could apply to $15 billion or more in USA goods. "But it's not going to happen like that anymore". Mexico, the US President said, had taken US auto companies, a big percentage of them.
