2026-09-08 date stated in the document
Canada's counter-tariffs became legally effective
Legally effective on this date under the Department of Finance Canada's own published schedule. This record has not yet observed duties assessed or collected on shipments.
2026-11-04 issuer-stated date
The first trade record covering the September reference month Period covered: 2026-09-01 — 2026-09-30
Entirely after the original August United States duties (2026-08-22)
Only partly after Canada's counter-tariffs (2026-09-08)
Nothing in this record separates price from volume, or one country's action from the other's. These calendar comparisons use the original United States duties and Canada’s counter-tariffs; the September scope changes and import exclusions are described separately in the legal record.
Daily truck counts now cover all September. The computed goods and services rows cover August, and the separately dated August Balance of Payments successor below retains its own definitions. September has a higher daily average and a lower United States plate share than August, with different calendar and holiday composition. Labour Day counts as a weekday in these calendar totals. These unadjusted counts do not establish a trade trend. Neither counts nor trade aggregates identify tariff effects or duties paid.

Next release
Next release: not stated in the captured evidence. Recheck when new daily observations or revisions appear.
Trigger
New days or revisions. A full month after the duties took effect would extend coverage, not identify their effect.

Preliminary, unadjusted entries: September has more weekdays and fewer weekend days than August; Labour Day is counted as a weekday. No holiday or seasonal adjustment is applied. Monthly averages do not establish a trade trend. Plates do not identify cargo origin, goods values or duties paid. The first captured month remains partial.
Provinces and statesState For every province, one United States state buys more of its domestic exports than any other -- and how much of a province's domestic-export sales to the United States that one state accounts for varies widely from province to province.

Trigger
The next release, updating every province's exports-by-state figures for a new month, or a province's largest destination changing.
Limitation
This province-by-state reading uses Statistics Canada's 'domestic exports' figures, which leave out goods shipped onward through Canada without being made here. That is a different, narrower total than the Canada-level export share reported elsewhere on this Monitor, and the two are never added together. A leftover category the table calls 'Other states' is not counted as a single state when finding each province's biggest customer. Where two states are exactly tied for largest in a province, this record refuses to break the tie and states that no single largest destination exists that month; no tie occurs in this reading. The full breakdown by product type, province, and state together is still not fetched. The observation ends before the duties became legally effective.

Evidence cutoff: 2026-10-13
Canada's trade with the United States sets prices, jobs, and policy choices across the economy, and the two countries' governments are now applying and answering tariff actions against each other. This view holds the record's own trade tables together in one place: what is directly observed, what a trade-agreement qualification narrows without closing, and what no institution yet measures at all.
The evidence cutoff states the scope of the review. Reference dates identify the periods measured by individual figures. The assessed date records when Countability last reconsidered the reading; the oldest member reading identifies the earliest period among its cited inputs. How to read the clock →

Since the last reading
New periodEvidence 2026-10-13
September is fully covered: 14,614.87 truck entries/day, including 1,811.87 with United States plates (12.40%). August: 14,144.03 entries/day and a 12.57% plate share. September has 22 weekdays and 8 weekend days; August has 21 and 10. These unadjusted averages do not establish a trade trend.
Truck coverage reaches September 30; the dated goods-trade successor remains August. This extends border-count coverage, without measuring tariff effects.
The full check
What happened: The October 13 captures added all 30 September days and July 26–27, 2025 in both truck series. The initial month remains partial; its average changes because coverage expanded, not because daily counts were revised. All held daily counts remain unchanged; future captures retain this native start.
Limitation: Preliminary daily entries to Canada, not freight volumes or goods values. Licence plates do not identify cargo origin or duties paid. Calendar composition differs between months; Labour Day is counted as a weekday and no holiday or seasonal adjustment is applied. No tariff effect is inferred.
Next trigger: New daily observations or revisions; no truck-specific next release date is established.

2026-10-09 · New period
The U.S. share of Canada’s goods exports was 68.34% over the twelve months through August 2026, compared with 73.88% over the preceding twelve months. U.S.-bound exports rose 8.1% in August from July, to $54.35 billion.
2026-09-14 · New reading
The United States import bans reach their legal effective date on September 29. Three proclamations cover specific Canadian alcoholic beverages, whey and molasses products, non-alcoholic beer and motorcycles in the tariff line for engines over 800 cc. These are listed products, not whole industries. Two further proclamations changed the goods subject to earlier 50 percent duties from September 15 and made those amended duties apply alongside Section 232 duties. The trade reading remains on July, before these September actions.
2026-09-14 · New period
August is fully covered: 14,144.03 truck entries/day, including 1,778.42 US-plated (12.57%). July: 14,329.90 entries/day, including 1,811.55 US-plated (12.64%). August has more weekend days; entries rose within both weekday and weekend groups. Plate shares rose on weekdays but fell on weekends; these averages do not establish a trade trend.

The U.S. Exposure Brief now compares July 2026 trade by road, rail, air, water and other transport. Each mode shows exports and imports separately, against July 2025 and against its own world total.
2026-09-03 · New period
Third reading, on the July 2026 trade record, and the share set a record. Over the twelve months through July 2026 the United States bought 68.50 per cent of Canada's goods exports, against 74.08 per cent a year earlier -- a one-year fall of 5.58 percentage points. That window is the lowest United States share in the twenty-nine-year monthly record, and unlike the previous low it stands alone: the next-lowest window, ending April 2026, reads 68.99 per cent, half a percentage point higher. The single month is sharper than the window. Exports to the United States fell 6.6 per cent from June to July, ending a run of five straight monthly rises, while exports to every other country together rose 7.4 per cent to the highest monthly level this record holds. In July, 33.7 per cent of Canada's goods exports went somewhere other than the United States. The reallocation is still narrow: 52.7 per cent of the twelve-month rest-of-world rise is the United Kingdom alone, and on the customs record the all-countries unwrought gold, silver and platinum-group-metals series is up 43.9 per cent window on window. Motor vehicles found almost no other buyer -- a 9.7 per cent fall in United States-bound sales against a rest-of-world gain worth 5.6 cents of every dollar lost.

Each province’s largest United States-state destination, domestic exports only
For each province, its largest single U.S.-state domestic-export destination and that state's share of the province's total U.S.-bound domestic exports, all HS sections, single latest reference month. 'Domestic exports' (excludes re-exports) is the only Trade member this cube populates at the provincial level -- the headline United States export share reported elsewhere on this Monitor reads 'Total exports' (includes re-exports), a different quantity, never merged with this row. Both sit on this page, and they do not reconcile: Canada's total exports to the United States for 2026-08-01 are $52,185,129,000, while the ten provinces' domestic exports to the United States sum to $48,515,842,000 -- a difference of $3,669,287,000. That difference is not decomposed here. The two figures differ in the cube's Trade member (total exports include re-exports; domestic exports do not) AND in its geographic coverage (the ten provinces exclude the territories and any province-not-specified member carried at the Canada level), and this record does not apportion the gap between those causes or divide either figure by the other. 'Other states', a residual cube member naming no single jurisdiction, is excluded from the largest-destination search. Where two states are exactly tied for largest in a province, this record refuses to break the tie by list position: it states that no single largest destination exists that month rather than naming whichever member the cube happens to list first. No tie occurs in this reading. Every province's 50 named states plus the District of Columbia and the residual are reconciled against that province's own independently fetched total before any share is derived.

Latest observation: 2026-08-01 — after the proclamations were signed (2026-07-20) but before the duties became legally effective (2026-08-22).
Limitation: The Canada-level series above are 2 of 15 x 4 x 53 x 22 cube members; the HS-section-by-province-by-state full micro-cut is still not fetched (controlled storage; fetch only what a reading needs). The province x US-state concentration reading above fetches all 15 x 10 x 52 x 1 province-by-state combinations at the all-HS-sections total, on the cube's 'Domestic exports' Trade member -- the only one populated at provincial grain, verified directly against the issuer's own published cube. The headline United States export share reported elsewhere on this Monitor reads 'Total exports', a different, broader quantity never merged with this row's provincial figures.
What no government publication states: the actual tariff coverage and effective rate applied to Canadian exports.
Blocked
Evidence gap
What share of Canada's exports to the United States is actually subject to tariffs right now, and at what effective rates?
What is missing: No official source on either side of the border publishes a continuously updated, machine-readable statement of the tariff status of Canadian exports. The operative documents state rates, scopes, and effective dates, but the duty actually applied to a shipment depends on USMCA qualification, product classification, exclusions, stacking rules, and later modifications — determinations spread across executive orders, proclamations, agency notices, and rulings, with no consolidated official series.
Consequence: The U.S. Exposure Brief shows the export record beside the dated tariff actions, but it cannot state what fraction of U.S.-bound exports is tariffed or at what effective rate — any such coverage percentage would be an outside model, not a reading of the record. Public claims about 'x per cent of exports now face tariffs' rest on estimates whose assumptions are rarely published.
What would close it: Either government publishing a continuously updated, openly licensed series of duty collections or tariff coverage on Canada–U.S. trade at product grain — or customs releasing duty-assessed values beside trade values on a compatible classification.
