When globalism was hot, then-prime minister Justin Trudeau tried to be hotter by deciding that Canada has “no core identity, no mainstream,” and suggesting Canada had become a “post-national state.” Now that nationalism is back in vogue, Prime Minister Mark Carney, unwilling or unable to counter U.S. President Donald Trump’s taunts and tariff barrage, has become an odd recipient of Canada’s quest for a U.S.-like national identity. Even as he rails against America’s temperamental chief executive, he has shown little interest in curbing his country’s own protectionist policies.
