Home > Guides > Duty on returns to Canada
Not on the same goods, no. If a parcel you imported leaves Canada again, for example a return to a US seller, the person who paid the duty can reclaim it through the CBSA Casual Refund Program with a B2G Informal Adjustment Request. If a parcel you sent comes back undelivered, it re-enters duty-free with proof it left Canada unchanged.
One honest boundary up front: LetterAgent sells Canada-only Canada Post Xpresspost shipping labels with a five-kilogram limit, so an international return shipment to a foreign seller is outside what the label flow can cover. Here is how the duties themselves work.
Returned-to-Canada situations split into two, and the rules are different for each:
| Scenario | Duty treatment | Who acts |
|---|---|---|
| You bought from abroad, paid duty at the door, and shipped it back | The duty you paid is reclaimable through the CBSA Casual Refund Program | You, as the importer who paid |
| Your seller shipped it DDP (duty paid by them) and you returned the item | The duty was never your money, so there is nothing for you to reclaim | The seller claims their own refund |
| You mailed a parcel abroad and it came back undelivered or refused | It re-enters Canada duty-free as returned goods, with proof it left unchanged | You, when it clears customs on the way back |
| Your package was lost abroad and a replacement is sent | The replacement is a fresh import and duty applies again on it | Whoever receives the replacement |
The Casual Refund Program exists for non-commercial importers: ordinary consumers who paid duty on a personal import and then exported the goods again. You file a B2G Informal Adjustment Request with the Canada Border Services Agency, asking for the duties and taxes back. It is an informal process, which mostly means no broker is required, but the paperwork standard is strict.
You need two documents stapled together, in effect: proof that the goods left Canada (the carrier's export receipt or tracking showing the export scan) and the original import receipt showing what you paid. The goods must be exported in the same condition they were imported, not used, altered, or partially consumed. Filing deadlines apply, so start the request as soon as the carrier confirms the export rather than waiting for the refund from the seller.
Only the person who paid the duty can reclaim it. That is where the delivery terms on your order matter. Under DAP (Delivered At Place), you as the buyer bore the import charges, so you are the importer of record and the refund is yours to claim. Under DDP (Delivered Duty Paid), the seller paid everything, which means any refunded duty is the seller's money, not yours. Check the shipping terms on your order confirmation before you spend time on a claim.
A parcel you mailed out that gets returned undelivered or refused is not a new import. When it re-enters Canada, customs can clear it as returned goods provided you can show it is the same item you exported: the original shipping receipt, the export tracking, and the returned parcel itself are usually enough. If you opened or altered the contents before it was re-shipped to you, the returned-goods treatment can be denied, which is one more reason to photograph the parcel before it leaves.
