Two CBSA updates issued between October 23 and November 5, 2026 require attention from importers and logistics providers, but neither creates a new Ontario-specific customs measure with a new effective date. The October 30 notice clarifies cargo-container reporting, while the October 23 revision updates guidance for U.S. surtaxes that were already effective September 8. For importers in Brampton, Toronto and Mississauga, the practical response is a file and process review—not a general change to routing.
What the two updates actually changed
On October 30, CBSA published Customs Notice 26-25 on the reporting of cargo containers through the ACI/eManifest system. The notice addresses containers that are full, empty or part of a consolidated shipment. It distinguishes temporarily used containers in international commercial transportation, empty containers, importer- or shipper-owned container banks or instruments of international trade, and containers imported into Canada for sale.
The notice describes requirements within the existing ACI/eManifest framework and is identified as having no regulatory impact. It does not state a new effective date. Containers imported into Canada for sale require their own cargo transmission and customs accounting, unlike containers handled as transport equipment or instruments of international trade.
On October 23, CBSA revised Customs Notice 26-23, which concerns administration of the United States Surtax Order (2026). The revision covers the accounting and treatment of existing 15%, 25% and 50% surtaxes, including the use of surtax codes 26186A, 26186B and 26186C in the Commercial Accounting Declaration. The notice also addresses CARM, EDI and API declaration channels, Chapter 98 and Chapter 99 goods, proof of origin, goods in transit, and eligible remission or relief claims.
Why the dates matter
The October 23 date is the date of the guidance revision, not the effective date of the underlying surtax measure. The source notice identifies September 8, 2026 as the effective date of that measure. Importers reviewing October entries should therefore avoid treating the publication date as the start of a new tariff obligation.
The same distinction applies to the October 30 container notice. It clarifies how existing reporting requirements apply to different container situations; it does not announce a new regulatory effective date. This is important when teams triage CBSA notices into tariff changes, declaration updates and operating clarifications.
Operational review for GTA shipment files
Container and consolidation data
Importers and forwarders handling consolidated cargo through Ontario highway, rail and intermodal networks should confirm that the container status used in the ACI/eManifest process matches the shipment structure. A container bank, an empty container, temporary transport equipment and a container imported for sale are treated as different situations in the notice.
Where a container is imported for sale, the responsible parties should verify that the cargo transmission and customs accounting are handled for the container itself. Where the container is transport equipment or part of a consolidation, the file should support the status reported to CBSA. These checks are relevant to freight moving through GTA distribution channels serving Brampton, Toronto and Mississauga, even though the notice applies nationally.
U.S.-origin goods and accounting data
Importers of covered U.S.-origin goods should review the tariff classification, origin documentation and surtax coding used for affected entries. The revised notice identifies the relevant surtax codes and permits declaration through CARM, EDI or API. A broker or carrier handling the transaction may need consistent information from the importer to support the Commercial Accounting Declaration.
Teams should also check whether a shipment involves Chapter 98 or Chapter 99 goods, goods in transit, or a claim for remission or other relief. The October revision discusses those treatments, but it does not convert every U.S.-origin shipment into a surtax entry. The review remains dependent on the goods, origin and applicable relief or exclusion conditions.
What importers should not infer
- The October 30 container notice does not establish a new importer-facing effective date.
- The October 23 surtax revision does not mean the surtax measure first took effect on October 23.
- The updates do not, on the information reviewed, establish a new Ontario-specific customs regulation.
- They do not support rerouting freight solely because the notices were published.
The most useful response is to retain the notices in the relevant operating or accounting files, confirm container-status data for consolidated shipments, and reconcile U.S.-origin surtax coding against the applicable entry facts. Importers with a specific shipment should have the classification, origin, container role and relief position reviewed before accounting or release decisions are finalized.
