Four routes reach a Canadian address and they do not cost the same. The crossing itself now sells at our own checkout, door to door: a 0.9 kg box to Toronto came back at $25.61 all-in on 2026-08-31, with the customs declaration completed before payment and duty left with the recipient. USPS's lightest tier is cheaper on paper, a published $19.40 to start under 4 lb, but that is a post office transaction rather than anything we sell. A courier account of your own is the volume answer, and for a box too big or heavy to price online the domestic leg to a border hub is still the cheapest first move. Every figure below carries the date it was read or quoted.
Door to door at checkout, the post office counter, your own courier account, or a domestic leg to a border hub.
This is the route that did not exist on this page until the end of August: a Canadian address typed into the calculator, live courier rates back, one payment, and the customs declaration completed before the label prints. The rows below are what our checkout returned for a single small test box. Each price is the whole checkout amount, with nothing added afterwards.
| Carrier | Service | Price | Transit returned |
|---|---|---|---|
| UPS | Worldwide Economy DDU | $25.61 | 8 business days |
| UPS | Standard | $25.83 | 2 business days |
| FedEx | International Priority | $35.67 | 1 business day |
Twenty-two cents separated the eight-day economy tier from the two-day one on that box, which is the kind of thing no static price list will ever tell you. Two limits belong next to those numbers: the origin has to be a US address, and every lane sells on a DDU basis, so whatever Canada assesses on the contents is billed to your recipient when the box lands rather than folded into the price above. No USPS option came back for this particular box either — a heavier parcel can return one on the same lane, which is why the published counter prices in the next section still matter.
USPS is the only one of the two with a retail price a private shipper can simply pay. UPS Worldwide Economy exists, but it sits behind a contract rather than a counter rate, which changes who this option is really for.
| Service | Who can buy it | Published starting price | Weight ceiling | Stated timing |
|---|---|---|---|---|
| USPS First-Class Package International Service | Anyone, at a counter or Click-N-Ship | Retail prices start at $19.40 | 4 lb (64 oz) | USPS states delivery varies by destination |
| USPS Priority Mail International | Anyone, at a counter or Click-N-Ship | $32.65 Flat Rate Envelope, or from $43.55 by weight | 4 lb for the Flat Rate Envelope and small box, up to 70 lb by weight | 6 to 10 business days to many major markets |
| UPS Worldwide Economy | Contract holders only, per UPS's own terms | No retail counter price published | Not stated on the page read | 5-8 days with duties prepaid (DDP), 5-12 days billed to the recipient (DDU) |
USPS names Canada explicitly in its Priority Mail International coverage list, alongside Mexico and Australia. UPS's own wording is blunter about the contract requirement: Worldwide Economy is "offered on a contract-only basis," which is why it never appears as a walk-up rate the way a Priority Mail label does. It is also why the same service name sits in the table above this one rather than on a receipt from a counter: it reaches a retail shipper through somebody whose account already carries it, with nothing to open on your side. USPS's products stay a counter transaction either way.
USPS also sells a Delivered Duty Paid option for outbound parcels, and Canada is on the list of destinations it covers. It is not automatically cheaper, but it removes a step that otherwise slows a parcel down at the Canadian side.
USPS states that its DDP service "allows senders to understand the total cost of delivery upfront and prepay those costs in advance," calculated at Click-N-Ship, a retail counter or through its shipping software. Choose it and the import duties, taxes, fees and a third-party service charge are added to the postage before the label prints; skip it and the recipient in Canada is billed separately once the parcel arrives, on top of whatever USPS's own delivery fee for handling a dutiable item comes to. Nineteen countries are on the eligible list, Canada among them, alongside the UK and most of the EU.
A large share of shippers sending regularly to Canada never buy an international label at all. They ship to a forwarder near the border on an ordinary domestic label, and the forwarder handles the crossing as a consolidated load rather than one parcel at a time. That first leg is exactly what our checkout prices, so here is what it looks like against a real border city.
| Carrier | Service | Price | Transit window returned |
|---|---|---|---|
| UPS | Ground Saver | $11.47 | Not supplied |
| USPS | Ground Advantage | $11.53 | 2-3 business days |
| UPS | Ground | $11.56 | 4-5 business days |
| FedEx | Ground Economy | $11.68 | 4-5 business days |
| USPS | Priority | $15.14 | 2-3 business days |
Four of those five landed inside a quarter of a dollar of each other, which makes the transit window worth more attention than the price on a run this short. Nothing in that table includes the border crossing itself; a forwarder charges separately for consolidating and clearing the load, and that fee is not one our checkout returns. What it does show is that the run to a border city costs about what any other mid-country domestic parcel costs, which is the whole appeal of routing through one.
Buy the crossing here and it is one transaction: live courier rates to the Canadian address, the customs declaration completed before payment, duty billed to your recipient when the box lands. The 0.9 kg test box above came back at $25.61 all-in, and the origin has to be a US address.
USPS First-Class Package International Service holds the lowest published starting price of anything on this page, $19.40, as long as the packed box stays under 4 lb. It is a counter or Click-N-Ship transaction rather than one of ours, and it did not come back among the rates for the box quoted above.
A courier account of your own starts paying for itself once enough parcels move to justify the paperwork of opening one, which is why it is priced per account rather than published as a retail rate. Below that volume, checkout gets you a courier service without the account.
Past parcel size, the domestic leg to a border hub is the part we can still quote to the dollar, and the crossing is arranged by whoever takes delivery of the load at the other end. Same answer when somebody is driving it over.
Whichever route carries the parcel, the CUSMA-based duty thresholds that decide whether a Canadian recipient owes anything sit on our Canada lane guide, and the customs form itself is covered on our customs forms and HS codes guide. The broader question of postal against courier against freight for any destination, not Canada specifically, is worked through on our cheapest way to ship overseas guide.
Carrier prices and eligibility change without notice. Treat the figures above as what each carrier published on the date shown, and confirm the current page before committing a shipment.
Two answers, and the box decides between them. Under 4 lb, with a post office within reach, USPS First-Class Package International Service holds the lowest published starting price at $19.40. To buy the whole crossing online instead, the cheapest option our checkout returned for a 0.9 kg box to Toronto on 2026-08-31 was UPS Worldwide Economy DDU at $25.61 all-in, eight business days, duty billed to the recipient on arrival.
Yes. USPS names Canada directly among the more than 180 countries its Priority Mail International product reaches, with a Flat Rate Envelope starting at $32.65 and by-weight pricing from $43.55, delivered in 6 to 10 business days to many major markets. First-Class Package International Service is cheaper still, from $19.40, but caps at 4 lb.
Not at a counter, no. UPS states that Worldwide Economy is offered on a contract-only basis, so it is not a rate a private individual walks up and buys the way a USPS parcel is. It does reach retail shippers through somebody whose account carries it: the DDU version of that service was the cheapest rate our own checkout returned for Canada on 2026-08-31, at $25.61 all-in for a 0.9 kg box. UPS quotes transit as 5 to 8 days when duties are prepaid and 5 to 12 days when the recipient pays them at delivery.
Sometimes, and mostly at volume. Routing the box to a forwarder near the border first turns the trip into an ordinary domestic parcel for the first leg, and the border crossing gets consolidated with other freight rather than billed to one box alone. It is not a shortcut around duty, just a cheaper first leg, and since our checkout now sells the Canada crossing directly, compare that math against a live door-to-door rate before choosing.
Possibly, depending on the declared value. Canada's own courier and mail thresholds decide that, and they are covered in full, with sources, on our Canada lane guide. Picking the cheapest shipping method does not change what the recipient is assessed at the border.
