"I have a good relationship with Justin Trudeau - I really did, other than he had a news conference that he had because he assumed I was in an airplane", the US president said at a news conference.
Those comments came after Trudeau's closing news conference at the G7 summit in Quebec on Saturday, when the prime minister said he had pushed back against the Trump administration's tariffs on steel and aluminum.

And lo and behold, look what happened".
The president said he had a "good relationship with Justin".
Freeland said she had a "good conversation" Sunday with US Trade Representative Robert Lighthizer, and that the pair would try to meet in Washington this week. "(Trudeau) learned. You can't do that.
In response, Trudeau, who has vowed to defend the system, made a point of making an unannounced visit to a "downtown diner" set up near Parliament Hill by farmers to demonstrate the high-quality food supply management helps provide.
