Issue 020  ·  Week of August 24, 2026

Canada’s counter-tariffs were announced for the Tuesday after Labour Day — and CBSA published the bonded-warehouse rules the day before the US duties landed

For about two weeks you have the date and the sectors and not the tariff lines. The one document published on a domain we can cite is the one about deferral — and about how deferral goes wrong.

Update — a correction we owe you: on August 19 we posted on X that Section 338’s 50% duties were in effect that morning. They were not. They had been paused hours earlier, and took effect at midnight ending Friday, August 21. The X post is still live and still wrong. A scheduled LinkedIn post carrying the same date was corrected before it published. The rate and the scope were right; the date was not. Issue 19 itself called the date certain and the outcome open, and the outcome stayed open until the last hours — which is why we write it that way.

§ 1 — The Dashboard

§ 2 — The Briefing

The clock ran out, and the second date is already set

If you spent Friday evening watching a deadline that had already slipped once, here is where it landed. The pause ended without a deal: the 50% Section 338 tariffs took effect at midnight ending Friday, August 21 (12:01 a.m. ET Saturday), negotiations were suspended that evening, and Canada announced it would match them dollar for dollar.

The matching duties come into force the Tuesday after Labour Day — September 8. The instrument and product list do not exist yet, so for two weeks you know the date and the sectors, and not your tariff lines.

§ 3 — The Connection

CBSA published the deferral rules the day before the duties landed

The Prime Minister’s Office published the suspension, the imposition and the dollar-for-dollar response on August 21 and 22. CBSA published Customs Notice 26-20 on August 21. Neither refers to the other; together they describe the same two weeks from opposite ends.

One caveat, and it is ours to own: the $28 billion figure, the sector list and the September 8 date come only from PMO documents, and pm.gc.ca is not on this publication’s citation list. We describe those, not link them. The departmental record is citable and says less. Global Affairs Canada’s August 14 readout is still its last on the trade file, and Finance Canada’s August 24 readout confirms the suspension and records the provinces being invited to give input on proposed countermeasures and impacted products — the list was still being consulted on, not circulated.

26-20 is the operational half. It sets out how goods under a tariff rate quota work inside a customs bonded warehouse, and CBSA is explicit that it is “not a change in policy, but a clarification.” A bonded warehouse is the first thing an importer reaches for when a duty is two weeks out; 26-20 is what it costs.

§ 4 — The Numbers

A week of currency is worth about three-quarters of one point of duty

Take a US$250,000 order of US-origin goods in a named sector. At Friday’s close of 1.3760 that is about C$344,000. At August 17’s 1.3865 it was about C$346,625 — a week of CAD firming took roughly C$2,625 off the order.

The duty term cannot be priced; the instrument does not exist. What can be sized is the sensitivity. On C$344,000, every point of duty is C$3,440, so the week’s currency move is worth about three-quarters of one point. A known date, an unknown rate, and a currency term too small to argue with it.

Which leaves timing. If those goods move under a tariff rate quota, 26-20 sets the terms: the Global Affairs permit must cover the date the goods exit, final accounting happens the same day as release, and a permit that expires in storage drops the entry out of the within-access rate, with penalties available. Swap in your own volumes; the structure is the point.

§ 5 — The Action

Reconcile permit expiry against exit date — one pass, under two hours

If you export into the US: USTR’s August index still carries nothing Canada-directed.

§ 6 — The Broader Picture

Output prices were already running hot before any of this

July’s Industrial Product Price Index was up 12.4% year over year; the Raw Materials Price Index was up 18.1% year over year but fell 2.2% month to month — input prices have run ahead of output prices over the year, with a one-month pause.

The counter-tariffs as announced would, from September 8, raise the Canadian-dollar cost of the US-sourced portion of that same input base — sectors named, tariff lines not. The planning question is not whether costs rise, but which line of the cost stack moves first, and whether your quotes have room for a duty carrying a date but not yet a rate.

§ 7 — The Question

Pull it forward, bond it, or wait for the list?

A note on framing: Fully Briefed synthesizes publicly available government source material and translates it into financial terms. This is education, not legal, customs, or tax advice. Nothing here interprets whether a specific product falls under a tariff rate quota or within the announced counter-tariff sectors, predicts what the eventual instrument will contain, or determines how your permits and declarations should be filed — Customs Notice 26-20 and Memorandum D17-2-1 govern, and your customs broker works the inputs.
