In June, the Pew Research Center found that 74 percent of Americans hold favorable views of Canada, while 34 percent view the country unfavorably. Their polling on Trump’s approval tells a similar story as Gallup. It began at 47 percent but dropped to 38 percent in August.

CNN’s chief data analyst explained why the president’s picking of a fight with Canada is “just something totally different.”

US President Donald Trump said he had a “very nice conversation” Wednesday with Canadian Prime Minister Mark Carney, despite the latest increase in tensions over trade between the two nations.
