Trump’s diplomatic trolling has sparked disbelief and defiance – but also revived questions of national identity

A lone figure takes to the stage, a giant maple leaf flag rippling on a screen behind him as he gingerly approaches the microphone.

“I’m not a lumberjack, or a fur trader,” he tells the crowd. “I have a prime minister, not a president. I speak English and French, not American. And I pronounce it ‘about’ – not ‘a boot’.”

The crowd, indifferent at first, grows increasingly enthusiastic as the man works his way through a catalogue of Canadian stereotypes, passing from diffidence to defiance before the climactic cry: “Canada is the second largest landmass! The first nation of hockey! And the best part of North America! My name is Joe! And I am Canadian!”

In response, Canadians have taken to acts of patriotism, small and large: one pilot flew his small plane in the shape of a maple leaf; sports fans have booed US teams; hats insisting “Canada is not for sale” have gone viral; consumers have pledged to buy only Canadian-made products – a pledge skewered in a viral sketch in which one shopper berates another for buying American ketchup.
