Canada and the U.S. Race to Finalize a Trade Deal Before Saturday's Tariff Deadline
Federal Trade Minister Dominic LeBlanc and chief negotiator Janice Charette planned to meet U.S. Trade Representative Jamieson Greer in Washington on Friday, hours before a 12:01 a.m. EDT Saturday deadline to finalize a Canada-U.S. trade deal and avert 50-per-cent U.S. tariffs on roughly US$20-billion in Canadian exports (The Globe and Mail).
The threatened tariffs cover about 5.2 per cent of the roughly US$383 billion in goods the United States imports from Canada each year. They were set to take effect at 12:01 a.m. Saturday under Section 338 of the Smoot-Hawley Tariff Act of 1930, a seldom-used provision of U.S. trade law. U.S. President Donald Trump postponed the tariffs by three days on Tuesday, saying the two countries had reached a deal but still needed to finalize its wording. Prime Minister Mark Carney cautioned that "important work still to be done" (The Globe and Mail).
The proposed deal would lock in 15-per-cent auto tariffs, lowering the current 25-per-cent rate on the sector with no carve-out (exemption) for Canadian or Mexican components (The Globe and Mail). Canada has also sought reductions to existing Section 232 tariffs — duties imposed on national security grounds — which currently sit at 50 per cent on steel and aluminum, 25 per cent on autos, and 10 to 25 per cent on forestry products. Those duties were strengthened by an April 2, 2026 proclamation building on Proclamation 9704 of March 8, 2018 (The Globe and Mail; whitehouse.gov).
The American demands extend well beyond tariff lines. Washington has asked Canada to end retaliatory tariffs on U.S. autos, modify dairy supply-management licence allocation (the system that controls how much imported dairy enters the Canadian market), and have provincial premiers drop retaliatory bans on U.S. alcohol and Buy Canadian procurement policies. The U.S. also sought right of first refusal on Canadian critical minerals, completion of the F-35 fighter jet purchase, participation in the planned Golden Dome missile defence system through U.S. military equipment procurement, and increased oil exports (The Globe and Mail).
Proclamation 11046, published August 19, temporarily suspends additional U.S. duties intended to offset Canadian discrimination against U.S. commerce in alcoholic beverages, dairy, and motor vehicles. The suspension appears to function as the holding mechanism while final wording is negotiated (whitehouse.gov).
The tariff conflict traces back to the earliest days of the Trump administration's second term. A 10-per-cent temporary import duty took effect February 24, 2025, under a 150-day proclamation. Canada responded on March 4, 2025, with 25-per-cent counter-tariffs on $30 billion in U.S. goods, part of a broader $155-billion retaliation package announced the previous day. Canada removed most of those counter-tariffs effective September 1, 2025 (pm.gc.ca; pm.gc.ca; canada.ca). On August 1, 2025, Trump announced 35-per-cent tariffs on Canadian exports not covered by any trade agreement, and on July 20, 2026, the administration signalled its intention to impose the new 50-per-cent tariff now at issue (pm.gc.ca; pm.gc.ca).
Canada has maintained a 25-per-cent tariff on non-preferential U.S. motor vehicle imports since April 9, 2025, a measure the White House has explicitly cited as discrimination against U.S. commerce (whitehouse.gov).
The negotiating dynamics carry political weight domestically. Manitoba Premier Wab Kinew criticized Carney for not holding out for a better deal, warning that the concessions could weaken Canada's position heading into the planned USMCA review — the mandatory 2026 reassessment of the trilateral trade agreement among Canada, the U.S. and Mexico. Kinew's intervention reflects a provincial concern that federal concessions on auto rates, dairy access, or critical-minerals priority could set precedents that compound during the trilateral review (The Globe and Mail).
The broader context here is that this negotiation is not a standalone free-trade agreement but a bilateral attempt to manage the layers of tariffs built up since early 2025. The proposed deal does not eliminate Section 232 duties on steel and aluminum; it would reduce auto tariffs from 25 to 15 per cent while removing any carve-out for regional content. That structure leaves substantial U.S. tariff exposure in place and effectively trades a lower rate for Canadian concessions on defence procurement, critical minerals, and dairy access. For negotiators and policy professionals tracking the file, the question is whether the bilateral deal constrains or pre-empts Canada's options when the USMCA review opens, particularly given that the auto rate and the absence of a carve-out would already represent a concession from CUSMA's duty-free threshold for qualifying vehicles.
