Canadian Prime Minister Justin Trudeau closed the summit by issuing a strong rebuke to Trump's trade threats, calling them "kind of insulting" and saying they would be met with retaliatory measures from July.
Trump has periodically expressed skepticism about the USA intelligence community's conclusion that the Kremlin meddled in the 2016 election that he won, and he has forcefully rejected assertions that Russian Federation was responsible for his victory.
European officials at the summit were shocked by the idea, or dismissive, and Tusk, while admitting that it was hard to be surprised by Trump's pronouncements any more, said: "Let's leave the G7 as it is".
This meant there were some pretty big characters in that room - German Chancellor Angela Merkel, British PM Theresa May, Canadian PM Justin Trudeau, French President Emmanuel Macron, as well as Europe chiefs Donald Tusk and Jean-Claude Juncker.
Mr. Trump did smile and wave with the other leaders at the traditional posed "family photo", on a bluff high above the St. Lawrence River, despite the obvious tensions. I think the G-8 would be better.
President Trump said he expects something will happen on trade, and that it will be positive. Trump hasn't said whether he is considering the proposal.
Despite earlier reports of a rant over trade from Trump, he said the meeting "was not contentious" and called the relationships between the leaders "outstanding".
The G7 summit came after the Trump administration decided last week to impose tariffs on steel and aluminum imports from the European Union (EU), Canada and Mexico, which has drawn strong opposition from the domestic business community and quick retaliation from major USA trading partners.
Trudeau again denounced Trump's decision to invoke national security concerns to impose tariffs on aluminum and steel as "insulting" to the Canadian war veterans who had fought alongside United States allies.

Manchester United Manager Jose Mourinho Makes Startling World Cup Prediction
Manchester United have confirmed on their official website that midfielder Fred will be at Old Trafford next season. United are in need of midfield reinforcements with Michael Carrick retiring and Marouane Fellaini out of contract.
But by insisting on re-negotiating every five years, Trump is diametrically opposed with Canada, which says the sunset clause would create perpetual uncertainty and harm long-term investment.
The US president also repeated his call for Putin to join the other leaders around the summit table.
President Donald Trump wrapped his short trip to Canada extolling his relationship with the G7 countries as a 10 out of 10, and blasting reports of rifts between the US and world as nothing more than "fake news".
"I'm happy to announce that we've released a joint communique by all seven countries", Trudeau said.
May reiterated the need to avoid tit-for-tat actions in a trade dispute between the European Union and the United States.
The tensions surrounding the tariffs underscore what appears to be a growing distance between the US and its allies over Trump's isolationist policies, including his decisions to withdraw from the Paris climate accord in 2017 and the Iran nuclear deal in May. "I blame our past leaders".
"We condemn all financial support of terrorism including terrorist groups sponsored by Iran". "It's going to stop now or we'll stop trading with them (other nations)".
It did not specifically mention the 2015 nuclear accord, which provided Tehran with relief from sanctions in return for curbs on its nuclear program.
But what has changed since Russia's ouster is Trump's election.
