CBSA’s July 7, 2026 trade-compliance priority update does not create an Ontario- or GTA-specific enforcement program. It does, however, identify a national set of goods and accounting issues that can affect importers operating warehouses and distribution networks in Mississauga, Brampton and Toronto. The practical response is to rank shipments and product lines by verification exposure before a request for records arrives.
What CBSA’s current priority list covers
The CBSA’s published trade-compliance verification page lists priorities involving steel and aluminum surtaxes, certain steel goods subject to tariff-rate quotas, U.S.-origin goods affected by Canadian surtax measures, Chinese steel and aluminum, Chinese electric vehicles, supply-managed goods, GST and excise-tax coding, preferential origin under CETA, CUKTCA and CPTPP, and energy commodities including electricity classified under Customs Tariff heading 27.16. The page was updated on July 7, 2026. CBSA trade-compliance verification priorities
The two steel-related priorities were identified by CBSA as having started in April 2026 and as remaining part of its evergreen, risk-based targeting process. The published results were national rather than Ontario-specific: three of six closed steel-and-aluminum cases were reported as being in error, with approximately $49,691 in assessed revenue. The certain-steel-goods priority had targeted 10 companies, with no cases closed at the time of the page update. CBSA trade-compliance verification priorities
Those results should not be read as a forecast for a particular GTA importer. They are a reason to separate higher-exposure product lines from routine entries and review the evidence supporting the declarations.
Build the review queue by exposure, not warehouse location
For a company receiving goods through Pearson or moving inventory along the 401/407 corridor, the relevant question is not whether the shipment is destined for Mississauga, Brampton or Toronto. The question is whether the goods fall within one of the listed national priorities and whether the importer can support the accounting declaration.
| Priority group | Review focus | Records to organise |
|---|---|---|
| Steel and aluminum | Applicable surtax treatment and material-origin information | Product specifications, supplier records and available melt-and-pour or smelt-and-cast information |
| Certain steel goods | Tariff classification and tariff-rate-quota treatment | Classification rationale, quota-related records and commercial documents |
| U.S.-origin or Chinese goods affected by Canadian measures | Origin, tariff classification, value for duty and surtax coding | Origin support, invoices, valuation records and accounting data |
| Supply-managed goods | Classification, origin and applicable import treatment | Product descriptions, permits or supporting commercial records where relevant |
| Tax and energy priorities | GST, excise-tax or energy-commodity coding | Product data, tax logic and the records supporting the declared tariff item |
The table is a practical review structure, not a substitute for checking the tariff item and facts for each product. Importers should discuss the correct evidence set with their customs broker before changing declarations.
The September surtax adds a shipment-level verification test
Customs Notice 26-23 states that, beginning September 8, 2026, certain U.S.-origin goods became subject to surtaxes of 15%, 25% or 50%, depending on the applicable schedule. The notice addresses goods originating in the United States even where they are shipped through another country, and it describes accounting through the Commercial Accounting Declaration using CARM, EDI or API. CBSA Customs Notice 26-23
For an affected importer, the control issue is broader than whether a surtax code was selected. The notice says that goods may be examined at importation or subjected to post-release verification covering tariff classification, value for duty, origin and other CBSA-administered requirements. CBSA Customs Notice 26-23
A useful review queue therefore starts with U.S.-origin products that could fall within the September 8 schedules. For each product family, the importer can compare the declared tariff item, origin determination, customs value and surtax coding against the underlying commercial records. If a product is sourced from the United States but routed through another country, the routing should not be treated as the origin analysis.
Prepare the evidence file for the current CARM framework
On September 9, 2026, CBSA revised Memorandum D11-6-8, which covers verification of non-free-trade-agreement origin, tariff classification and value for duty. The revision addresses CARM Release 3 and the use of the Commercial Accounting Declaration in place of the former B3-3 and B2 forms. CBSA Memorandum D11-6-8
The memorandum describes verification methods that can include questionnaires, verification letters, site visits and other information-gathering steps. It also confirms that CBSA may reassess origin, tariff classification or value for duty following a verification. CBSA Memorandum D11-6-8
That framework makes record retrieval part of the compliance control. Importers and customs agents can discuss whether the following items are consistently connected to the CAD and the product master data:
- the tariff-classification rationale and product descriptions;
- origin support, including material-origin information where steel or aluminum is involved;
- commercial invoices and records supporting value for duty;
- the applicable surtax schedule and the code reported in the CAD;
- records showing how corrections, adjustments or unusual transactions were handled.
The goal is not to create a separate file for every entry without regard to risk. It is to ensure that higher-priority product families have a documented explanation that can be retrieved when the broker or importer needs to respond to a verification request.
A practical 30-day review sequence
- Identify affected product families. Start with steel, aluminum, U.S.-origin goods covered by surtax measures, Chinese-origin priority goods, supply-managed products and energy commodities listed by CBSA. CBSA trade-compliance verification priorities
- Separate classification questions from origin questions. A supplier’s country of shipment may not answer the origin issue, and a product description may not establish the correct tariff item. Keep the two analyses traceable to their supporting records.
- Test the accounting path. For goods affected by the September 8 surtax order, compare the applicable schedule with the CAD data transmitted through CARM, EDI or API. CBSA Customs Notice 26-23
- Check valuation support. Review whether the value for duty recorded for higher-risk goods can be reconciled to invoices and the importer’s transaction records. The verification framework specifically covers value for duty. CBSA Memorandum D11-6-8
- Escalate unresolved items. Ask the broker to review products where material-origin information, tariff-rate-quota treatment, surtax coding or valuation support is incomplete before the next related shipment is accounted for.
What this means for GTA importers
There is no published CBSA verification priority directed specifically at Brampton, Toronto or Mississauga. The exposure is determined by the goods, their origin, their classification, their value and the quality of the accounting records. A Peel Region warehouse or a Toronto distribution operation can therefore face the same national priorities as an importer elsewhere in Canada if it handles the covered products.
Importers should treat the July 7 priority list, the September 8 surtax rules and the September 9 verification memorandum as connected control signals, while keeping their roles distinct: the first identifies CBSA’s published targeting areas, the second creates surtax accounting exposure for covered U.S.-origin goods, and the third describes the CARM-era verification process. The immediate broker discussion should focus on which product families belong in the review queue and whether the supporting evidence can be produced consistently from the importer’s records.
