Canada Post’s domestic fuel surcharge climbed to 39.5%, while FedEx lowered parts of its international schedule. For ecommerce brands, the split is another reason to stop treating one carrier as the default.

Last updated: August 17, 2026

Two parcels leave the same Canadian fulfillment centre on the same morning. One is headed to Calgary. The other is crossing the border into Chicago.

This week, the domestic parcel may carry a heavier fuel burden, even as some of the cross-border charges move in the opposite direction.

It sounds contradictory, but it isn’t. Domestic and international carrier surcharges follow different fuel markets, indexes and adjustment schedules. They can rise and fall independently, creating small windows where one service becomes more competitive while another quietly gets more expensive.

For brands shipping thousands of orders, those small movements add up quickly.

What changed this week

For August 17 through August 23, Canada Post raised its domestic fuel surcharge from 38% to 39.5%. Its U.S. and international charges also increased: parcel services moved from 22.25% to 23%, while packet services rose from 20.25% to 21%.

The domestic surcharge applies to services including Priority, Xpresspost, Expedited Parcel and Regular Parcel. Canada Post reviews the rate weekly using Canadian diesel-price data with a two-week reporting lag. The current figures are available on Canada Post’s fuel-surcharge page.

FedEx moved differently.

Its intra-Canada Express and Ground surcharges remained at an elevated 43.5%. However, its international Express surcharge declined from 36.75% to 35%, while its Ground surcharge for Canada–U.S. shipments eased from 20.25% to 20%.

The changes are published in FedEx Canada’s current surcharge schedule.

Purolator adds another layer to the picture. Its monthly courier surcharge fell from 39.5% to 36% on August 3 and is scheduled to remain there through September 6, according to Purolator’s published rates.

The market is not moving in one direction. It is separating by carrier, service and lane.

A fuel surcharge is not a percentage of the whole invoice

A 39.5% fuel surcharge does not necessarily mean the complete shipping bill is 39.5% higher.

The percentage is applied to eligible transportation charges and, depending on the carrier, certain additional services. Residential delivery, remote-area service, oversized handling, address corrections, pickup fees and other accessorial charges may also affect the final invoice.

Contracted discounts can reduce the base transportation rate, but they do not always apply equally to fuel and accessorial charges.

That is why the advertised carrier discount is often a poor measure of the actual cost.

A simple example shows how the weekly changes compound. If an eligible domestic transportation charge is $10, an increase from 38% to 39.5% adds 15 cents to the parcel. Across 10,000 weekly shipments, that is another $1,500 in cost from a movement of only 1.5 percentage points.

The same math works in reverse. On a $20 international transportation charge, FedEx’s 1.75-point Express reduction saves approximately 35 cents per shipment.

Neither amount looks dramatic on one label. At scale, both matter.

Why domestic and cross-border costs can move apart

Canada Post and FedEx base their intra-Canada fuel surcharges largely on Canadian diesel prices. FedEx international Express services use a U.S. jet-fuel benchmark, while Canada–U.S. Ground services reference U.S. highway diesel.

Purolator uses a four-week Canadian diesel average and generally resets its courier surcharge monthly. Canada Post and FedEx make weekly adjustments.

Each carrier is therefore reacting to a different benchmark over a different period. A decline in U.S. jet fuel can lower an international surcharge while Canadian diesel keeps domestic costs elevated.

This lag also means today’s surcharge does not necessarily reflect today’s fuel market. A major rise or fall in energy prices may take several weeks to reach a carrier invoice.

Lower cross-border fuel does not mean lower landed cost

The easing at FedEx is useful, but brands should keep it in perspective.

Fuel is one line in the cross-border cost stack. Duties, tariffs, brokerage, customs-entry fees, taxes and importer-of-record expenses can outweigh a modest carrier reduction.

A shipment can become cheaper to transport and more expensive to import at the same time.

This matters even more following the suspension of U.S. duty-free de minimis treatment and the introduction of new product-specific tariffs. Carrier pricing and customs exposure need to be calculated together before a brand decides whether to fulfill an order from Canada or hold inventory inside the United States.

The carrier should be chosen order by order

The old approach was to negotiate a national-carrier agreement, set that carrier as the default and review the pricing once a year.

That leaves money on the table in a market where surcharges move every week.

A better approach compares the complete expected cost of each order using its destination, service level, weight, dimensions and applicable surcharges. It should also consider delivery performance, claims experience and tracking quality. The lowest label price is not always the lowest operational cost.

Brands should review their shipping data by lane rather than averaging everything together. Toronto-to-Montreal, Toronto-to-Vancouver and Toronto-to-Chicago are three different cost problems. One carrier does not need to win all three.

Inventory placement matters as well. When stock is positioned closer to Canadian customers, the underlying zone and transportation charge can fall. Because the fuel surcharge is calculated as a percentage of that charge, regional fulfillment can reduce both the base cost and the dollar value of the surcharge.

For brands with sustained U.S. demand, holding inventory in an American fulfillment centre can convert repeated cross-border parcel movements into domestic U.S. deliveries. The import cost still needs to be addressed when inventory enters the country, but the customer order no longer has to clear the border one parcel at a time.

How 247 Fulfillment responds

At 247 Fulfillment, we use a multi-carrier network instead of forcing every order through one provider.

Our Parcel Plus routing system compares available services based on cost, destination and delivery requirements. Combined with fulfillment locations in Ontario, British Columbia, Utah and Florida, this gives brands more control over where inventory sits and how each order moves.

The practical response to changing carrier costs is straightforward:

Refresh carrier and surcharge data regularly.
Compare the final expected charge, not just the negotiated base rate.
Route domestic and cross-border orders separately.
Audit invoices for accessorial and fuel-charge errors.
Position inventory closer to the customers creating the most volume.
Avoid locking long-term customer shipping prices to a cost that changes weekly.

Carrier prices will keep moving. The advantage belongs to the operation that can move with them.

The cheapest carrier is no longer one company. It is the right decision for each order.

Published fuel surcharges are subject to change. Actual billed costs depend on the shipper’s agreement, service, zone, package characteristics and applicable additional charges.
