Canada and the United States are in the final stretch of trade talks aimed at averting a fresh 50% tariff wave on roughly $20 billion of Canadian goods after President Donald Trump moved an original August 19 trigger date to August 22. The framework under negotiation would lower duties on Canadian-built vehicles from 25% to 15% and cut steel and aluminum tariffs from 50% to 25%, with quotas possibly attached, while Ottawa weighs concessions on U.S. alcohol sales and potential dairy access that have drawn mixed provincial reactions. Trade Minister Dominic LeBlanc and U.S. Trade Representative Jamieson Greer are leading the talks, which Washington has tied to Depression-era tariff law and complaints over Canadian automotive, dairy, and alcohol policies. A collapse by the new deadline would stack the full 50% levy on top of existing metals, lumber, and auto measures and could weigh on the Canadian dollar, whereas a deal would ease pressure on deeply integrated cross-border auto and metals supply chains.
