50% Tariffs Take Effect on $20B of Canadian Goods; Carney: 'We're at War'

The Section 338 tariffs took legal effect at 12:01am ET Saturday after the deal collapsed, hitting roughly $20 billion (C$28 billion) of Canadian goods — about 5% of Canada's exports to the US — including electronics, plastics, wood, paper, dairy, alcohol, cement, clothing and hockey equipment. Energy, potash, fish, critical minerals and goods already under Section 232 national-security tariffs remained exempt. At a Saturday press conference, Carney said 'You're at war when you get attacked. We got attacked,' and separately called the US move 'a miscalculation,' while acknowledging the tariffs would raise costs and reduce choice for Canadians and also hit 'innocent' US companies and states.
