He added: "Why should I, as President of the United States, allow countries to continue to make Massive Trade Surpluses, as they have for decades, while our Farmers, Workers & Taxpayers have such a big and unfair price to pay?"
"Prime Minister Trudeau is being so indignant, bringing up the relationship that the USA and Canada had over the many years and all sorts of other things. but he doesn't bring up the fact that they charge up to 300 percent on dairy - hurting our Farmers, killing our Agriculture!"
Following Trudeau's statement during the news conference, Trump posted two tweets slamming his words as "false" and accused the Canadian prime minister of being dishonest. "Not fair to the PEOPLE of America!" he tweeted.
EU nations are set to impose counter-measures on USA 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.

Trump's favourite U.S. network Fox News invited Canada's outspoken former conservative prime minister Stephen Harper, usually a reliable Trudeau critic, to discuss the crisis. The official North Korean news agency said Sunday Kim is prepared to talk about "denuclearization" and a "durable peace".
That was short-lived after Trump again took to Twitter following Prime Minister Trudeau reaffirmation of Canada's position on the tariffs. "This I've never seen before, nor has anyone else", Mulroney said.
Sometimes described as a "mini-Obama", not least due to his omnipresent smile, Trudeau is clearly far closer in his political alignments to the US Democratic Party than Trump's Republicans. The first issue involved the World Trade Organization.
"We hope it doesn't come to that, but if the USA tariffs remain in effect, we will impose our tariffs on July 1", he said. In the most Canadian manner (polite), not directly targeting anyone unlike POTUS (President of the United States).
