The US and Canada are embroiled in a tariff war, and it may "will come at a cost" for Ottawa as the Canadian PM Mark Carney had warned. But the fight is proving a win for at rather unusual sectors: from the ice-cream counter and gift shops to wineries and even defence manufacturing. As American goods face fresh Canadian tariffs, local businesses have seen an uptick due to the "buy Canadian" wave. Prime Minister Mark Carney has warned that moving away from the US as Canada's biggest trading partner "will come at a cost," adding that the counter-tariffs on American goods "are necessary to protect our workers".
