When U.S. President Donald Trump last came to Canada for a Group of Seven summit, the enduring image was of him seated with his arms folded defiantly as then-German Chancellor Angela Merkel stared daggers at him.

President Donald Trump departed the White House on Sunday en route to Western Canada for the annual G7 summit, promising to secure trade deals weeks ahead of a tariff hike deadline.

World leaders could face a tense G7 in Alberta, with U.S. President Donald Trump’s trade war and the Israel-Iran conflict front and centre. Prime Minister Mark Carney is set to meet Trump Monday to continue tariff negotiations.

The summit will revolve around the president, reflecting the wider picture of a world working out Mr Trump and shaping its response accordingly.

This summit was meant to showcase Carney’s global leadership and Canada’s push for independence from the US. But the Middle East conflict has now overshadowed those goals, posing a major diplomatic challenge.

Canada’s Mark Carney will host world leaders in Kananaskis in coming days, with his plans for a unity G7 summit to unblock trade at the mercy of a new Mideast war and the temperament of Donald Trump.
