Ottawa mounts full-court press for Canada-U.S. trade deal ahead of Aug. 19 tariff deadline

Canada is launching an all-out diplomatic push to close an interim trade deal with the United States before Aug. 19, when a new round of 50 per cent U.S. tariffs on roughly five per cent of Canadian goods is set to take effect. (Globe and Mail, Aug. 11; CBC News, Aug. 4)

Trade Minister Dominic LeBlanc flew to Washington on Tuesday for his third meeting with U.S. Trade Representative Jamieson Greer in as many weeks. Canada's chief trade negotiator, Janice Charette, spent the weekend at the Canadian embassy in Washington working with trade negotiators and experts ahead of the session. LeBlanc, Charette and Greer, along with their entourages, were expected to meet at 1:30 p.m. ET at the Winder Building, the USTR's offices near the White House. (Globe and Mail, Aug. 11)

LeBlanc had been scheduled to return to Washington on Monday, but his aircraft could not land due to turbulence from a thunderstorm and returned to Montreal, where he stayed overnight before flying down Tuesday morning. (Globe and Mail, Aug. 11)

The two sides are working toward an interim agreement in which Canada would accept a long list of U.S. demands in exchange for some relief on the Trump administration's existing tariffs. The U.S. is demanding that Canada accept export quotas on steel and aluminum, remove retaliatory tariffs on U.S. products such as autos, return American alcohol to store shelves, remove provincial procurement restrictions, and agree to Washington's interpretation of how dairy tariff-rate quotas should be allocated. In exchange, the parties have discussed the U.S. lowering Section 232 tariffs on steel and aluminum while leaving some level of tariff in place. Canada is also pushing for relief on the auto and forestry tariffs. (Globe and Mail, Aug. 11)

The tariff architecture Canada is trying to unwind is extensive. President Donald Trump imposed duties of 50 per cent on steel and aluminum, 25 per cent on autos, 10 per cent on lumber and 25 per cent on wooden furniture under Section 232 of the Trade Expansion Act of 1962 after returning to power in 2025. Last month, Trump unveiled plans to levy 50-per-cent tariffs on US$20-billion worth of additional goods, including alcohol, dairy products and electronics, under Section 338 of the Smoot-Hawley Tariff Act of 1930. The Aug. 19 deadline would see that latest round take effect. (Globe and Mail, Aug. 11; Reuters, Aug. 7)

Negotiators on the Canadian side have been reviving a quota-for-tariff-relief proposal that would place Canadian steel and aluminum exports under a quota system in return for lower U.S. duties, a framework that echoes the managed-trade approach Washington has previously favoured in sectoral agreements.

Prime Minister Mark Carney has said he hopes to see all of Trump's sectoral tariffs dealt with before Aug. 19. LeBlanc, however, has cautioned that he was not signalling whether the government expects to succeed in its bid for a deal before the deadline. Sources with knowledge of the talks told The Globe and Mail that although the contours of a deal have been taking shape, nothing has been agreed to and Trump has not signed off on anything.

The stakes of the provincial procurement demand are worth noting. Removing provincial procurement restrictions would touch a constitutionally sensitive area, since Crown corporations and sub-national purchasing preferences fall squarely within provincial jurisdiction under the division of powers. Ottawa can negotiate international commitments on procurement, but delivering on any such commitment requires provincial buy-in, a dynamic that has complicated Canadian trade negotiating positions going back to the original CETA and CUSMA rounds. Whether the federal government can secure provincial consent within the time frame of these talks is an open question.

The dairy quota allocation demand touches a separate but equally fraught domestic file. Washington has long argued that Canada's administration of tariff-rate quotas under CUSMA has channelled too much import share to processors rather than retailers, a complaint that has been the subject of multiple dispute-panel rulings. Accepting Washington's interpretation would require adjustments to how supply-managed sectors allocate import access, which has historically generated pushback from dairy lobby groups and Quebec and Ontario members of Parliament across party lines.

Looking at the broader negotiating logic, the interim-deal structure under discussion suggests Ottawa is prepared to absorb meaningful concessions on export restraints, procurement access and dairy administration in exchange for partial tariff relief. The asymmetry is notable: the U.S. would lower but not eliminate Section 232 duties, while Canada would move on a catalogue of structural demands. Whether that exchange ratio is politically defensible at home, particularly with Conservative Leader Pierre Poilievre having publicly urged the government not to concede to Trump's demands, will depend heavily on the specific tariff reductions Washington ultimately offers. (Globe and Mail, Aug. 9)

With eight days remaining before the Aug. 19 deadline, the Winder Building meeting on Tuesday afternoon is the most concrete opportunity for both sides to narrow remaining gaps. Whether it produces enough to justify a signing ceremony before the next tariff round lands, or simply narrows the field for a further round of talks, remains the central question.
