"Canada is very clear", she said.
U.S. President Donald Trump angered his G7 allies last week by slapping them with hefty tariffs on steel and aluminum - a move that prompted Canada and the European Union to threaten duties of their own.
Trump went on to say that the United States gets "unfairly clobbered" on trade despite "protecting Europe at great financial loss".
But the House of Commons wasn't the only place Trudeau found support. On Twitter, Trump complained that Trudeau had criticized US trade policy - specifically USA tariffs on Canadian metals - after the Canadian premier had "acted so meek and mild" in their one-on-one meeting.
White House economic adviser Larry Kudlow continued the war of words between the Trump administration and Canadian Prime Minister Justin Trudeau on Sunday morning. Mexico, Canada, China and others have treated them unfairly.
On Sunday, Trudeau ignored the barbs from Trump's advisors, tweeting a link to the G7 communique and hailing the "historic and important agreement we all reached".
"Don't take the bait, don't dance this dance of countervailing insults and emotional outbursts".
"Stay calm, keep moving forward, be the adult and come back with meaningful and substantive policies at the table that makes sense to arrive at an appropriate NAFTA outcome".
"They pay only a fraction of the cost - and laugh", he wrote, adding that the European Union needed to pay "much more" to help fund the global military alliance, which comprises 28 members including the UK, US, Germany, Canada and Turkey. He had other things, bigger things, on his plate in Singapore.
He told Fox News Mr. Trump "did the courtesy to Justin Trudeau to travel up to Quebec for that summit".
For good measure, Trump sent out more tweets the morning of June 8 before his arrival in Quebec - "Canada charges the US a 270% tariff on Dairy Products!"
Trump - who has a history of hair-trigger responses to slights - landed in Singapore on Sunday for the Tuesday summit meeting with Kim. They accused Trudeau of betraying Trump and stabbing him in the back.
Trump also took aim at Canadian Prime Minister Justin Trudeau and said he might double down on import tariffs by hitting the sensitive auto industry, throwing the G7's efforts to show a united front into disarray. He claims these unfair trade practices cost American jobs and somehow create a national security risk by weakening producers. "And no subsidies. I even said, 'no tariffs!'" Trump insisted. And tariffs are going to come way down, because people can not continue to do that. He says that we are the problem with tariffs.
"Let me correct a mistake I made", Navarro said at a Wall Street Journal conference, according to video provided by the Journal's CFO Network. And he urged Canada's industrial leaders to remain calm in the face of ongoing threats from the U.S president.
In a news conference June 9 shortly before his departure from Quebec, Trump brings up his problems with trading with his friends - "It's going to change, a hundred per cent". These countermeasures amount up to 16.6 billion Canadian dollars (about 12 billion US dollars) in imports of steel, aluminum, and other products from the Unites States, and are set to come into effect on July 1 this year.
