A review of official Canadian customs and border materials published or updated from September 29 through October 12, 2026 found no clearly new substantive customs, tariff, import-control, permit, CARM or border regulation taking effect for Ontario or GTA importers during that period. The practical result for businesses in Mississauga, Toronto and Brampton is a status check—not a new filing or tariff deadline identified in the reviewed material.
What the review found
The October 7 edition of the Canada Gazette, Part II did not contain an apparent new customs, import-control, surtax or border instrument affecting ordinary commercial importers, based on the material reviewed. The Gazette edition is available at Canada Gazette, Part II, October 7, 2026.
CBSA also revised Memorandum D10-15-22 on October 9. The revision concerns the classification of automatic-transmission parts under tariff item 9961.00.00, but CBSA described the change as related to plain language and accessibility rather than a new tariff measure or new effective-date requirement. Importers reviewing classification controls should therefore distinguish an updated explanation from a newly imposed obligation. The memorandum is available at CBSA Memorandum D10-15-22.
Two developments still require monitoring
CREDITS procedure revision
CBSA revised Customs Notice 25-26 on October 1. The notice addresses how CREDITS Program participants submit refund claims when surtax was paid at importation. The procedure described in the notice separates surtax claims into a separate batch, combines the surtax and duty in the “Duty” field, and requires a separate surtax template to be sent to CBSA. The details appear in Customs Notice 25-26.
This is an operational item for customs brokers and refund-service participants using CREDITS. Importers who rely on a broker or refund provider for these claims may wish to confirm that the provider has incorporated the revised submission workflow. The official listing and notice do not state a separate legal commencement date, so October 1 should be treated as the revision or publication date rather than assumed to be a new statutory effective date.
Forced-labour consultation results
On October 8, the Government of Canada released “What We Heard” reports concerning proposed measures under Bill C-35 to strengthen Canada’s forced-labour import ban. The release states that consultation feedback will inform future legislative and regulatory measures. It does not identify a new import prohibition, enacted regulation or new importer documentation requirement. The release is available at Government of Canada releases What We Heard reports on fighting forced labour.
What GTA importers should do with this update
For current shipment planning, the reviewed material does not support changing tariff rates, release procedures or import documentation solely because of an October publication date. Importers who participate in CREDITS-related refund activity should separate that operational review from ordinary entry processing. Businesses sourcing goods through Ontario distribution operations may also want to keep the Bill C-35 consultation on their regulatory watch list without treating it as a current compliance change.
- Record the publication or revision date separately from any stated effective date.
- Ask the broker or refund provider whether CREDITS surtax claims are being submitted under the revised procedure.
- Track future Bill C-35 legislative or regulatory steps rather than creating a new documentation requirement based only on the consultation release.
- Continue evaluating classification guidance on its substance; an accessibility revision alone does not establish a new tariff measure.
This update is a review of the cited public materials, not a determination of the requirements for a particular product, transaction or importer account.
