The gestures of support came after Trump and Prime Minister Justin Trudeau had a clash of words after the G7 leaders' summit over the weekend in La Malbaie, Que.
Trump pulled out of endorsing a joint communique after the G7 meet finished on Saturday with the U.S. president accusing Trudeau, the summit's chairman, of dishonesty.
And the young Canadian leader, who has attempted to maintain a public facade of friendship with the United States leader, confirmed that he would regretfully impose retaliatory tariffs on United States goods from next month to offset the steel levy.
"The historic and important agreement we all reached at #G7Charlevoix will help make our economies stronger & people more prosperous, protect our democracies, safeguard our environment and protect women & girls' rights around the world". The dispute weighed on the Canadian dollar on Monday.
"That has meant the dismantling of multilateral agreements, the pulling out of the Paris climate change accords and the destabilisation of the Iran nuclear deal, and now the imposition of tariffs on steel and aluminium". "Do Timber & Lumber in US?"
"In Maine, we have a special relationship with Canada", she wrote.
Trump pushed back at the reporter's agenda and said the relationship between the USA and her allies is a "ten".
Later Sunday, Trump's trade adviser Peter Navarro piles on - "There's a special place in hell for any foreign leader that engages in bad-faith diplomacy with President Donald J. Trump and then tries to stab him in the back on the way out the door".
Washington has said it put tariffs in place after having national security concerns about Canada, but Canada has rejected the suggestion.
"We should think very carefully about a situation in which we are retaliating against one of our closest neighbors and our best friends and longtime allies", said Dr. Robert Kudrle, of the Humphrey School of Public Policy.
Trudeau himself sidestepped questions about the attacks from Washington.
Mr Trump has consistently said that countries that have a trade surplus with the U.S. - meaning they export more to the USA than they import - are "taking advantage" of the US.
But other Republicans have held their tongue, wary of doing anything to undermine Trump's negotiating hand ahead of the President's meeting with Kim in Singapore.
But the response by US lawmakers, business executives and officials falls short of the concerted and effective nationwide pressure campaign Canadian officials had hoped would be launched if a major threat developed.
German Chancellor Angela Merkel said in a television interview on Sunday that the summit is a "sobering" and "depressing" experience with an outcome that "wasn't a great thing".
One new reason for optimism in Ottawa is a new-found strength in numbers.
Trump refused to sign a joint agreement with US allies at the end of the summit and threatened to cut off trade with them unless deals were renegotiated. The countries coordinated closely on their response, Freeland said.
Canada's most powerful response to this diplomatic dissonance, short of the mutually assured destruction of blocking energy exports, is a popular mobilization that gives individual Canadians a stake in the trade war effort.
Domestically, Trudeau has also received support from all corners, and is backed by all opposition parties.
May 31 - The Trump administration announces that Canada will no longer be exempt from steel and aluminum tariffs, prompting the Trudeau government to announce its own counter-measures. "He's talked about pulling out of NAFTA but hasn't done so", noted the first source.
