Ottawa's LeBlanc Back at Greer's Door to Close Tariff Deal
Dominic LeBlanc flew back to Washington on Thursday for another session with Jamieson Greer, with a deal to head off fresh U.S. tariffs on Canada still unsigned.
Canada-U.S. Trade Minister Dominic LeBlanc returned to Washington on Thursday, August 20, 2026, for another meeting with U.S. Trade Representative Jamieson Greer as the two sides work to finalize an agreement that would avert a new round of U.S. tariffs on Canadian goods.
Canada's trade file has become a commuter route. Dominic LeBlanc, the minister responsible for Canada-U.S. trade, was back in Washington on Thursday for another sit-down with U.S. Trade Representative Jamieson Greer, with both governments still working to convert months of talks into a signed agreement that would keep a new round of American tariffs from taking effect.
The meeting, reported by BNN Bloomberg, is the latest in a sequence of face-to-face sessions between the two men. Neither side has published terms. What is known is the shape of the problem: the deal is not done, the tariff threat has not been withdrawn, and the negotiation has moved into the stage where the remaining gaps are the hardest ones.
Why the shuttle diplomacy itself is the story
Trade agreements that are close to completion do not usually require repeated in-person visits by a cabinet minister. Technical annexes get handled by officials; ministers appear to sign. When a minister keeps flying down, it signals that the outstanding items are political rather than procedural — the kind of questions that need someone with authority to trade one concession against another in the room.
That is the reasonable reading of LeBlanc's return trip. "Finalization" is a word that covers a wide range of conditions, from initialling a text to still arguing over which sectors are covered and for how long. Until a document exists, Canadian exporters are planning against a tariff schedule that may or may not arrive.
For Ottawa, the calculation is straightforward and uncomfortable. The United States is by far Canada's largest export market, and the integrated nature of North American supply chains — autos, energy, metals, agriculture, forest products — means a tariff applied at the border does not fall on one company in one province. It travels through parts networks and processing chains on both sides of the line. That is also the strongest Canadian argument at the table, and it is one Greer's office has heard before.
What businesses on both sides are doing while they wait
Uncertainty has a cost even when the tariff never lands. Purchasing managers hedge by pulling orders forward or delaying them. Firms with the option to hold inventory in the United States do so. Capital projects that depend on cross-border shipments get pushed a quarter. Insurers and lenders reprice risk on receivables. None of this shows up as a tariff line item, but it shows up in margins.
Companies most exposed tend to share three characteristics: a high share of revenue derived from U.S. customers, thin operating margins that cannot absorb a duty, and limited ability to switch suppliers or ship from an American facility. Larger multinationals with plants on both sides of the border have flexibility that a mid-sized Ontario or Quebec manufacturer does not.
- Exporters with U.S.-heavy order books face the most direct revenue exposure.
- Firms with U.S. production capacity can shift volumes and blunt the impact.
- Businesses reliant on cross-border inputs face cost pressure regardless of which way the duties run.
- Currency moves can offset or amplify a tariff, depending on direction.
The absence of published terms is itself a planning problem. A company cannot model a tariff whose rate, scope and start date are unknown, so many are modelling several scenarios at once and committing to none.
The market backdrop on the day of the meeting
A company cannot model a tariff whose rate, scope and start date are unknown, so many are modelling several scenarios at once and committing to none.
Equities were soft while the two ministers met. As of the last trade at 17:53:40 GMT on Thursday, August 20, 2026, the S&P 500 tracker (SPY) stood at $764.85, down 0.55% from the previous close of $769.06 and trading in a day range of $764.23 to $768.15. The Nasdaq 100 fund (QQQ) was at $711.25, off 0.67% against a prior close of $716.08. The Dow tracker (DIA) was weakest of the three at $528.92, down 1.00% from $534.27.
That pattern — the Dow lagging the broader index and the tech-heavy benchmark — is what one would expect on a day when industrial and consumer-facing names take the brunt of the selling. It is not evidence that the Washington meeting moved markets; a single day's tape rarely isolates one cause, and trade headlines compete with rates, earnings and energy prices for attention. But it is a fair description of the environment into which any tariff announcement would land: an equity market already trading defensively rather than one primed to shrug off a new cost on cross-border goods.
What would confirm a deal, and what would signal it has slipped
The tell for progress is a joint statement, or parallel statements timed together, from LeBlanc's office and the Office of the U.S. Trade Representative. Anything less — a readout describing "productive discussions" without a text — means the gap remains.
The tell for trouble is the opposite: a scheduled meeting that does not produce a follow-up date, or a shift in language from finalizing to negotiating. Watch also for whether the tariff threat is formally suspended, extended, or simply left to sit. A suspension buys time; leaving it in place while talks continue keeps pressure on the Canadian side and is a recognizable negotiating posture.
Canadian investors with exposure to export-weighted industrials, autos and resource processors have the most riding on which way this goes. So do American buyers who source north of the border and would pay the duty themselves. The absence of news from Thursday's meeting is not neutral — every week without a signed agreement is another week of deferred decisions on both sides of the border.

Frequently asked questions
Who is Dominic LeBlanc and what is his role?
Dominic LeBlanc is Canada's minister responsible for Canada-U.S. trade. He is Ottawa's lead negotiator in talks with Washington and returned to the U.S. capital on Thursday, August 20, 2026, for another meeting with the U.S. Trade Representative aimed at finalizing an agreement that would prevent a new round of American tariffs on Canadian goods.
Who is Jamieson Greer?
Jamieson Greer is the United States Trade Representative, the cabinet-level official who leads American trade negotiations and administers U.S. trade policy. He has met repeatedly with Canada's trade minister Dominic LeBlanc as the two governments work toward a deal that would head off fresh tariffs on Canadian exports.
Has a Canada-U.S. tariff deal been signed?
No. As of the August 20, 2026 meeting, work was continuing to finalize an agreement. No terms have been published by either government, and the threatened new round of U.S. tariffs had not been formally withdrawn. Until a text exists, exporters on both sides of the border are planning against an uncertain tariff schedule.
Which sectors would new U.S. tariffs affect?
Neither government has published the scope of the threatened tariffs, so the specific sectors are not confirmed. In general, Canadian industries most exposed to U.S. trade measures are those with high U.S. revenue shares, thin margins and integrated cross-border supply chains. Without published terms, companies cannot model the rate, coverage or start date.
How were U.S. markets trading on the day of the meeting?
Major U.S. benchmarks were lower. As of the last trade at 17:53:40 GMT on August 20, 2026, the S&P 500 tracker SPY was at $764.85, down 0.55%. The Nasdaq 100 fund QQQ was at $711.25, down 0.67%. The Dow tracker DIA lagged at $528.92, down 1.00% on the day.
What should investors watch next in these talks?
The clearest confirmation of progress would be a joint statement, or coordinated parallel statements, from LeBlanc's office and the Office of the U.S. Trade Representative setting out agreed terms. Signs of slippage include readouts citing productive discussions without a text, no follow-up meeting date, or language shifting from finalizing back to negotiating.
