US President Donald Trump has announced new 50 per cent tariffs on a range of Canadian goods, accusing Canada of discriminatory trade practices against American alcohol, automobile and dairy products.

The tariffs, set to take effect in 30 days, will apply to products including wine, hockey sticks and cement. The White House said energy, potash and goods already subject to sector-specific tariffs will be exempt.

The new duties, imposed under Section 338 of the Tariff Act of 1930, will also apply to products covered by the US-Mexico-Canada Agreement (USMCA).

Canadian Prime Minister Mark Carney condemned the move as a “direct violation” of the USMCA and said Canada was ready to intensify talks with Washington to resolve the dispute.

The White House defended the tariffs, accusing Canada of retaliating against previous US trade measures by removing American alcohol from store shelves, favouring European dairy imports and limiting US vehicle exports.
