Canada Post Fuel Surcharges Increase September 28: What Sellers Should Recalculate
Canada Post’s weekly parcel fuel percentages increase September 28. See the affected service groups, a worked cost example and the checks to make now.
Information checked as of September 27, 2026.
Canada Post’s parcel fuel surcharges increase for shipments dated September 28 through October 4. The domestic percentage moves to 46.50% from 44.50%; USA and International Parcel moves to 26.50% from 25.50%; and USA and International Packet moves to 24.50% from 23.50%. Those are increases of 2.00, 1.00 and 1.00 percentage points respectively—not relative increases of 2%, 1% and 1%.
The three service groups are not interchangeable
| Canada Post service group | Sept. 21–27 | Sept. 28–Oct. 4 | Change |
|---|---|---|---|
| Domestic Services | 44.50% | 46.50% | +2.00 percentage points |
| USA and International Parcel Services | 25.50% | 26.50% | +1.00 point |
| USA and International Packet Services | 23.50% | 24.50% | +1.00 point |
Canada Post’s official fuel-surcharge page identifies the service scope. Domestic includes Priority, Xpresspost, Expedited Parcel and Regular Parcel. The international parcel group includes Xpresspost USA, Xpresspost International, International Parcel Air and Surface, and Expedited Parcel USA. The packet group includes Tracked Packet USA and International plus Small Packet USA and International.
This is a weekly table. Canada Post says it updates the percentages each Monday and reflects them on the invoice. It is not an annual list-rate change, and it does not by itself tell you the final all-in price of a label.
What the percentage-point change means
The relative increase is larger than the percentage-point label may suggest. Domestic moves from 44.50% to 46.50%, a 2-point change but approximately a 4.49% relative increase in the fuel percentage. Both cross-border groups rise by 1 point; that is approximately 3.92% relative for Parcel and 4.26% relative for Packet.
Do not apply those relative figures to the whole invoice. They describe how the surcharge percentage changed. Your actual dollar increase depends on the eligible shipping amount, shipment mix, contract pricing, service, weight and destination.
A clearly hypothetical cost example
Assume a domestic parcel has a hypothetical CAD $20.00 eligible transportation charge before fuel. This is not a Canada Post quote and does not include taxes or other charges.
- At 44.50%, the illustrative fuel amount is CAD $20.00 × 0.445 = CAD $8.90.
- At 46.50%, the illustrative fuel amount is CAD $20.00 × 0.465 = CAD $9.30.
- Illustrative difference: CAD $0.40 per parcel.
If 3,000 shipments in a week had the same eligible amount, the illustrative change would be CAD $1,200. Real invoices will differ; use the eligible amount and calculation terms in your agreement or rating system.
Five checks to make before Monday
- Version the table by shipment date. Do not overwrite the prior week if you need to audit labels created before September 28.
- Map every service to the correct group. Tracked Packet and Xpresspost USA do not use the same percentage.
- Re-rate a real order sample. Include common weights, regions and residential destinations rather than one “average” parcel.
- Compare customer recovery with carrier cost. A static checkout charge can quietly under-recover when fuel changes weekly.
- Audit the first invoice. Verify shipment date, service code, eligible amount and applied percentage.
Use all-in cost—not fuel percentage alone
A lower fuel percentage does not guarantee a lower shipment cost. The useful comparison is the carrier’s net transportation charge plus fuel, delivery-area or residential charges, package-related fees and any contract-specific items for the same parcel. Our guides to parcel invoice auditing, multi-carrier routing rules and a dimensional-weight audit show how to build that comparison.
The practical answer is simple: load the September 28 table as a dated rule, re-rate representative orders and inspect the first invoice. If your team needs help turning carrier tables into repeatable shipping controls, 247 Fulfillment can review the shipment data and assumptions behind the model.
