Canada's $27.6B Counter-Tariffs Begin September 8 Amid Escalation Threats

Canada imposes counter-tariffs — retaliatory taxes on imports — of 15 to 50 per cent on $27.6 billion in U.S. goods starting September 8, 2026, after trade talks collapsed August 21. Ottawa threatens to expand to $155 billion if U.S. tariffs persist. Trump separately threatens 50 per cent tariffs on Canadian vehicles and parts, hitting deeply integrated cross-border manufacturing.
