Canada to Impose Dollar-for-Dollar Retaliatory Tariffs on US Goods from 8 September

Canada will impose retaliatory tariffs matching US measures dollar for dollar, beginning on 8 September 2026, Prime Minister Mark Carney announced after trade negotiations with the United States collapsed.

The US imposed 50 percent tariffs on roughly $20 billion of Canadian goods that took effect on 22 August 2026. The duties cover items including wine, dairy, cement, clothing and hockey equipment, in addition to existing levies on steel, aluminium, autos and lumber.

Carney said last-minute changes in the US proposed terms were unfair and uneconomic and called into question the reliability of any deal. He directed Canadian negotiators to return to Ottawa and suspended talks.

The Canadian countermeasures will target US steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics. Detailed lists will be released in the coming days. Carney stated that Canada had been willing to drop remaining retaliatory tariffs on steel, aluminium and autos if the United States substantially lowered its own duties.

No further talks are currently scheduled. Ontario Premier Doug Ford criticised the US approach, describing President Donald Trump in strong terms and signalling readiness for confrontation. Trump responded by threatening higher tariffs on Canadian vehicles, auto parts and steel from January 2027.

The dispute forms part of a broader deterioration in Canada-US trade relations since the Trump administration returned to office. The new US tariffs do not apply to goods covered by the US-Mexico-Canada Agreement preferences in the same way as earlier measures, affecting about 5 percent of Canadian exports to the United States.

Both sides have framed the measures as protecting domestic workers and supply chains. The economic impact will depend on the final product lists and any further escalation.
