Trudeau said at the press conference that Canada would not be "pushed around" by the United States. The two leaders also stood side-by-side for a photo of the world leaders together, showing that Trudeau is visibly taller than Donald Trump.

"Canada does not conduct its diplomacy through ad hominem attacks".
"From day one, we have said that we expected moments of drama and that we would keep calm and carry on throughout this drama", she said.
