Trudeau avoided mentioning China by name - the country that the US and Canada must now carefully monitor, under the terms of the agreement, to prevent cheap foreign steel from being dumped into North America.
China has since detained two Canadians on claims of espionage and sentenced a third to death for drug smuggling. The federal Conservatives were also critical. The foreign ministry in Canada had no immediate comment. Jean Simard, president and CEO of the Canadian Aluminum Association, says the deal will put "an end to the harmful uncertainty that is impeding the development of the Canadian and North American aluminum industry".
Reacting to the announcement, Dieter Kempf, head of the German industrial federation, said "cars do not threaten the national security of the United States". They were hurting Canadian consumers, Canadian workers, and American workers and American consumers. The United States past year imported $192 billion worth of passenger vehicles and $159 billion in auto parts.
"After extensive discussions on trade in steel and aluminum. the United States and Canada have reached an understanding as follows, the United States and Canada agree to eliminate, no later than two days from the issuance of this statement, all tariffs the United States imposed under Section 232 on imports of aluminum and steel products from Canada".
"I'm pleased to announce that we've just reached an agreement with Canada and Mexico and will be selling our product into those countries, without the imposition of tariffs", Trump said at an event in the United States capital. They paused the discussions to give Canada time to negotiate with the US, he said.
As part of the agreement to lift the levies, the US will be able to impose new tariffs on Canada and Mexico if they don't do enough to prevent any surge of imports of the metals, according to the people.
The rules of origin requirement could also be an impediment to Canadian exports, creating additional red tape for US companies importing steel and aluminium from Canada and pushing them to choose American suppliers instead.
At the time Freeland called it the "the strongest trade action Canada has taken in the post-war era".
"Removing the metal tariffs restores zero-tariff trade to US pork's largest export market", Herring said.
Friday's tariff agreement, which enlists Canada's help in policing the North American steel market against Chinese dumping, could be seen as pushing Canada even deeper into America's corner.
For some, however, the scars will linger.
President Donald Trump pumps his fist before speaking at the National Association of REALTORS Legislative Meetings and Trade Expo, Friday, May 17, 2019, in Washington.
Once America's neighbors were included, the levies drew retaliation with tariffs on a host of USA products.
"Ending tariffs means Canadians can get back to work", Hassan Yussuf, the president of the Canadian Labour Congress, said on Twitter.
The decision sparked tit-for-tat duties from Canada and Mexico on U.S. farming goods and other products, and became an obstacle for lawmakers in all three nations to ratifying the U.S. -Mexico-Canada Agreement.
