Weight settles it. Tracked Packet USA caps at 2 kg with no dimension over 60 cm: under that, it is Canada Post's economy tracked lane to the United States. Expedited Parcel USA takes up to 30 kg and much larger boxes, and it carries an on-time delivery guarantee that Tracked Packet does not. Both quote a comparable 4 to 7 business day estimate. Always confirm the price and the date at the rate step: that is the only reliable source for your specific shipment.
The 2 kg rule decides it almost every time
Most Canadian shippers think they are choosing between two speeds. They are actually choosing between two formats. Tracked Packet USA is a small-packet service: 2 kg maximum, no single dimension over 60 cm, and length plus width plus height capped at 90 cm. The moment a parcel breaks any one of those three ceilings, Tracked Packet is simply not eligible, whatever the price would have been.
Expedited Parcel USA covers everything else: up to 30 kg, no dimension beyond 200 cm, and length plus girth up to 274 cm. It is the full parcel service on Canada Post's US network. Put plainly: under 2 kg you have a real choice, over 2 kg the decision has already been made for you.
- Jewellery, cosmetics, light apparel, accessories, printed matter: almost always under 2 kg, so Tracked Packet is eligible.
- Boxed footwear, small appliances, multi-item orders: frequently cross 2 kg, so Expedited Parcel.
- Light but bulky items (cushions, lampshades, foam parts): can pass the 2 kg test and fail the 60 cm one. Measure before you assume.
Tracked Packet USA: the tracked small packet
Tracked Packet USA (service code USA.TP) is built for cross-border e-commerce with a small per-item footprint. It is tracked end to end, it moves through the postal network to final delivery by USPS, and its estimate is 4 to 7 business days. What it does not carry is an on-time delivery guarantee. Canada Post classes it as a non-guaranteed service, which means the posted transit time is an estimate rather than a commitment.
For a retailer shipping dozens of small parcels a week into the United States, this is usually the right trade: the tracking number keeps customers calm, and the missing guarantee rarely costs anything when the goods are not time-critical.
Expedited Parcel USA: the guaranteed parcel
Expedited Parcel USA (service code USA.EP) is the standard parcel service into the United States. It is tracked like Tracked Packet, its estimate is the same 4 to 7 business days, but Canada Post publishes an on-time delivery guarantee for it. It also accepts substantially bigger and heavier boxes.
One practical detail that gets missed: past 22.7 kg (50 lb), a parcel needs an "Overweight Parcel" sticker for handler safety. It does not change eligibility, but it does change your packing-bench routine.
| Criterion | Tracked Packet USA | Expedited Parcel USA |
|---|---|---|
| Service code | USA.TP | USA.EP |
| Maximum weight | 2 kg | 30 kg |
| Maximum dimension | 60 cm | 200 cm |
| Size formula | L + W + H: 90 cm | length + girth: 274 cm |
| Tracking | Yes, end to end | Yes, end to end |
| On-time delivery guarantee | No (non-guaranteed service) | Yes |
| Estimated transit | 4 to 7 business days | 4 to 7 business days |
| Signature included | No | No |
The guarantee is the only real difference at equal speed
This is the point most comparisons miss. At the same size, under 2 kg, both services quote the same 4 to 7 business day window. So the difference is not speed: it is what recourse you have when the window is missed. Expedited Parcel USA is a guaranteed service, Tracked Packet USA is not.
In practice: if a late shipment costs you real money (a dated gift order, a replacement part, a customer who paid for speed), the guarantee is worth the price gap. For ordinary restocking, it almost never pays for itself.
Guarantee terms, exclusions, surcharges and postal-code coverage change, and prices vary by lane, dimensional weight and your own agreement. Treat the figures above as eligibility rules, not as a price: confirm the amount and the delivery date at the rate step before you buy the label.
The other Canada Post services into the United States
Tracked Packet and Expedited Parcel are not alone on the US lane. If your shipment is more urgent, or conversely less urgent and does not need tracking, two other options are worth a look.
| Service | Max weight | Tracked | Guaranteed | Estimated transit |
|---|---|---|---|---|
| Small Packet USA – Air | 2 kg | No | No | 6 to 10 business days |
| Tracked Packet – USA | 2 kg | Yes | No | 4 to 7 business days |
| Expedited Parcel USA | 30 kg | Yes | Yes | 4 to 7 business days |
| Xpresspost USA | 30 kg | Yes | Yes | 2 to 3 business days |
| Priority Worldwide USA | 30 kg | Yes | Yes | 1 to 3 business days |
Small Packet USA Air shares exactly the same size ceilings as Tracked Packet (2 kg, 60 cm, 90 cm total), but without tracking and with a longer estimate. For e-commerce, the missing tracking number generates enough "where is my order" email to erase the saving. Xpresspost USA and Priority Worldwide USA are the fast, guaranteed options, with signature included on Priority Worldwide.
How to decide for your shipment
The sequence is short. Measure and weigh first: past 2 kg or 60 cm, Expedited Parcel USA is your only option of the two. Under those ceilings, ask whether a delay would cost you money: if yes, pay for the guarantee; if no, Tracked Packet does the job. Then compare.
Because Canada Post is not the only route into the United States. On some lanes and some weights, UPS, FedEx or Purolator come out cheaper or faster for the same box, and the difference is not predictable from any general rule: it depends on the postal code, the dimensional weight and the day. That is exactly what a multi-carrier comparison is for. With a free MesColis account, no contract and no minimum, you enter the parcel once and see the Canada Post services beside the other carriers, each with its real arrival date and all-in price. MesColis is not the cheapest on every lane, and does not claim to be: the point is seeing which one is, today, for this parcel.
Frequently asked questions
Is Tracked Packet USA cheaper than Expedited Parcel USA?
For a small light parcel, Tracked Packet is generally the economy option in the tracked lineup, but the gap depends on the lane, the weight and your rate agreement. Compare both at the rate step rather than assuming.
Who actually delivers my parcel in the United States?
Canada Post carries the shipment to the border and hands it to the US postal network (USPS) for final delivery. That is why tracking continues under the same number once the parcel is in the United States.
Do I need a customs declaration for both services?
Yes. Any commercial shipment into the United States needs a customs declaration listing the item descriptions, their value and their country of origin, whatever service you pick. The service does not change the customs obligation.
