On October 15, 2026, the Canada Border Services Agency revised Memorandum D19-6-3, Importation of Energy-using Products. The revision records that responsibility for the Energy Efficiency Regulations moved from Natural Resources Canada to Environment and Climate Change Canada on July 30, 2026, but it does not call for an immediate change to the existing Customs Single Window submission settings.
What changed on October 15
The revised memorandum updates the federal department responsible for the Energy Efficiency Regulations and replaces references to the Single Window Initiative with Customs Single Window. CBSA also describes the remaining edits as minor editorial changes.
The institutional change is therefore clear: Environment and Climate Change Canada is now the department associated with the Energy Efficiency Regulations. The border-processing change is more limited. CBSA states that system changes to Customs Single Window have not yet been finalized.
The source for the revised guidance is CBSA Memorandum D19-6-3.
What importers should do with the transition
Importers and dealers bringing regulated energy-using products into Canada for sale or lease are generally expected to provide prescribed product information to CBSA at import. The October 15 guidance creates a distinction between the department named in the regulatory framework and the system reference used in a release request.
Until Customs Single Window changes are finalized, clients should continue submitting release requests using the existing settings that reference NRCan. Replacing the existing setting solely because the responsible department has changed could put an importer out of step with the current system instruction.
- Identify shipments that fall within the regulated energy-using product process.
- Review internal instructions and broker release data for references to the responsible department.
- Retain the current NRCan-referencing Customs Single Window setting unless updated system instructions say otherwise.
- Separate the regulatory-owner update from any future technical change to the release workflow.
Why the distinction matters in shipment controls
Product and data mapping
A product may remain operationally subject to the same import-information process even while the department named in guidance changes. Importers should therefore review product records, prescribed information and release instructions as separate control points rather than treating the departmental transfer as an automatic change to every data field.
For a company managing imports through facilities in Mississauga, Brampton or Toronto, this distinction is relevant when purchasing, compliance and customs teams maintain different versions of product and release instructions. A revised department name may need to be reflected in compliance documentation, while the current Customs Single Window transaction setting remains unchanged.
Broker instructions and exception handling
Importers who use a broker are generally best served by giving the broker a dated copy of the applicable product and release instructions, including any internal list of regulated goods. The October 15 guidance supports maintaining the existing NRCan system reference during the interim period, while monitoring for a later Customs Single Window update.
If a release request is prepared with a new departmental reference before the system change is finalized, the shipment should be reviewed against the current CBSA instruction rather than assumed to be correct because the institutional transfer has already occurred.
What has not been reported in this update
The supplied CBSA guidance does not identify a new tariff rate, surtax, Ontario-specific border measure or broad change to customs treatment. It is a memorandum revision focused on responsibility references, Customs Single Window terminology and interim submission handling.
That makes the practical task one of controlled change management: update the regulatory owner in the relevant compliance records, keep the existing NRCan-referencing system setting for now, and watch for a subsequent instruction confirming that Customs Single Window changes are ready.
Questions for the next internal review
- Which imported products in the company’s catalogue are handled as regulated energy-using products?
- Where is prescribed product information maintained before the release request is submitted?
- Do procurement, compliance and customs instructions identify the same responsible department?
- Does the broker’s current Customs Single Window instruction still reference NRCan as directed by the October 15 guidance?
