The Canadian prime minister met with President Trump days after being elected on an anti-Trump platform as relations between the two allies are at a historic nadir.

A meeting between the leaders of Canada and the United States is not usually considered a high-stakes showdown, but there was little ordinary about this encounter after Trump spent months musing about annexing Canada and turning it into the 51st state.

When President Donald Trump welcomes his new Canadian counterpart to the White House on Tuesday, among the questions looming over their Oval Office encounter will be whether Trump will agree to attend a major summit Prime Minister Mark Carney is hosting next month in Alberta.
