There is no universal winner between Nationex and Canada Post: the right pick depends on the address, the destination and the parcel. Start with two simple filters. A PO box points you to Canada Post, and a shipment leaving Canada rules Nationex out. For a street address in Canada, get both quotes for the same parcel and compare the total, the estimated date and how the parcel is handed over.
Start with the delivery address
The first cut is not made on price. Canada Post delivers to PO boxes and post office counters; a courier generally needs a street address where it can hand the parcel over. If your customer gave a PO box, the question is settled before you compare rates.
For a street address, both carriers can be in the running, but coverage is never a given. Check that the lane is served for both of your postal codes, especially in remote areas, rather than inferring it from a carrier's reputation.
| Criterion | Canada Post | Nationex |
|---|---|---|
| Type of carrier | National postal operator | Regional courier |
| PO box | Yes, with an eligible postal service | Street address in general: confirm |
| Shipments leaving Canada | Yes, USA and international | Canada only on MesColis |
| Lane coverage | Confirm for your postal codes | Confirm for your postal codes |
| Price | Depends on parcel and service: at the quote step | Depends on parcel and service: at the quote step |
| Weekend delivery | Confirm for the chosen service | Confirm for the chosen service |
Canada only, or outside Canada
Canada Post offers services to the United States and internationally, on top of its domestic network. On MesColis, Nationex is offered only for Canada-to-Canada shipments: for a parcel going to the US or abroad it will not appear in the comparison, and other carriers will be in the running instead.
If you sell both in Quebec and outside the country, nothing forces you to pick one carrier for everything. You can compare parcel by parcel and pick a different carrier depending on the destination.
Compare rates for the same parcel
There is no universal price winner. The result changes with the postal codes, the actual weight, the packed dimensions, the dimensional weight and the options you choose. A carrier's reputation for being "cheap" proves nothing for your parcel.
- Use the same postal codes, weight and packed dimensions for both quotes.
- Compare the total, not the base rate: surcharges, fuel and options add up.
- Record the exact service each carrier offers, not just its name.
- Keep the quotes to compare the final invoice with your original assumptions.
Transit: read the estimated date
Do not infer transit time from a regional presence or a one-off experience. Check the estimated date shown for the chosen service and both addresses, and account for the day the parcel is actually handed to the carrier. An estimate is not a guarantee: any commitment has its own terms, exclusions and claim procedure.
Rates, transit times, service areas and weekend options change with the service and the account. Nothing in this guide is a commitment from Nationex or Canada Post: confirm the price and the date at the quote step, for your parcel.
Drop-off or pickup: handing the parcel over
How the parcel is handed over matters as much as price when you ship often. Canada Post has a large network of post office counters for drop-off, and also offers pickup. For Nationex, check the pickup or drop-off options available at your address before promising a ship date to your customers.
Either way, print the label before handover and note the cut-off time for your area: a parcel handed over after the cut-off leaves the next business day, which moves the estimated date.
Compare the two side by side
MesColis is not a carrier. For a shipment within Canada, we show Canada Post, Nationex and the other carriers that serve your lane side by side, each with its price and estimated date for the same parcel. You then choose on what matters for that shipment: price, date or handover.
With a free MesColis account, no contract and no minimum volume, you compare the carriers that serve your lane before you buy the label.
