Details about ShipStation's Canada Post integration. Includes requirements, connection process, features, integration notes, and troubleshooting.
ShipStation is a dedicated Canada Post partner! We allow users to get rates and to create both domestic and international shipping labels for Canada Post shipments.
Use ShipStation with either a Canada Post Commercial or SFSB (Solutions for Small Business) account and you can create manifests for your outbound shipments.
Connection Requirements:
An active Commercial or Small Business account with Canada Post.
Manifest Requirements:
-
Commercial account holders are required to manifest each day's shipments. Failure to manifest shipments may result in additional monthly invoice fees.
Create manifests directly in ShipStation using the End of Day process. Then each day when you drop off your Shipments, provide the Canada Post driver or Canada Post counter person with a physical copy of the manifest.
Small Business accounts have no manifest requirements.

-

If connecting a Commercial account, you must have a Business Profile created for Canada Post. See Create a Canada Post Business Profile for details.

Click Connect.
You'll be redirected to Canada Post to complete the connection.

Click Agree and Continue to agree to the Terms and Conditions.
To connect a Canada Post Commercial account to ShipStation, you must have created a Business Profile in Canada Post that uses your commercial contract number. If you have used your Commercial Canada Post account with another shipping provider, it's likely you have already created this. However, if you're new to Canada Post or recently upgraded from a Solutions for Small Business account, you'll need to create a new user profile that uses the contract information.

Common ShipStation Features
|
|
|
Canada Post return labels are only available to Commercial account holders. Return labels cannot be voided, cannot include carrier insurance, and will always require Signature confirmation.
-
If you use a Commercial Canada Post account, you must manifest your shipments!
You can create manifests directly in ShipStation using our End of Day process. You can then provide Canada Post with a physical copy of the manifest.
Labels that have been manifested cannot be voided in ShipStation. However, you can log into your Commercial Canada Post account to void or cancel manifested labels.
Manifests are not required for Solutions for Small Business accounts.
Cannot electronically submit customs documentation for international shipments. You must provide any necessary customs documents with your shipments.
Does not support Label Branding (Logos on Labels).
Only Label Message 1 & 2 are supported. Label Message 3 will not appear on Canada Post labels.
Special characters can prevent label creation. You may need to remove special characters such as & @ ` ~ | ! % * < > to create the label.
You may incur extra fees if you drop-off packages at a deposit location that is not considered to be your nearest drop-off location. Use the Canada Post Find a Deposit Location tool to find your nearest deposit location.
Canada Post uses a specific formula called 'Volumetric Equivalent of Actual Weight'. This accounts for the weight and dimensions of the package and charges for the shipment based on volume when applicable.
Does not support multi-package shipments. You must split the shipment, and will not see a + sign for multiple packages as with UPS, FedEx, or Purolator.
Card for Pickup confirmation option not available currently.
Here are some common issues, potential causes, and troubleshooting tips.
Issue |
How to troubleshoot or resolve |
|---|---|
Error "Method of payment Account/Credit Card is not available" when creating shipping labels or closing shipments |
This error indicates that the payment method selected for the Canada Post integration is not valid, the credit card on file needs to be updated, or you have reached the credit limit of your account. To resolve this error, check your Canada Post account and make sure the credit card is up to date or there is still a balance on the Account payment method. If neither of the above is the problem, go to IMPORTANT: Be sure to close any open End of Day forms for your CP shipments before you update your billing information! |
End of Day error: A system error has occurred. Please try again later. If the problem persists, please contact the Canada Post help desk. |
This message appears in your Canada Post (CP) End of Day Feeds if you changed your billing info in your CP account prior to closing out your shipments for the day. If you have trouble closing CP shipments after changing your billing info, check the EOD feeds to see if this error is present anywhere. If it is, you must contact CP for assistance with closing those shipments. We also advise your to make sure all shipments for the day are closed prior to making any billing or account settings changes from within your CP account. If you changed account settings since the last time you created shipments, Canada Post does not allow you to manifest from a third-party application like ShipStation. Shipments created after the change should manifest without issue. |
Error "/rs/soap/shipment/v7: cvc-simple-type 1: element unit-weight value '0.000' is not a valid instance of the element type" when creating international shipments |
This error message occurs when ShipStation rounds the weight value for an international shipment and the calculation ends up with a value of 0. This can happen if you have a lightweight shipment that contains a customs line item that has a high quantity (such as a 100 gram package with a customs quantity of 500.) To resolve this issue, adjust your customs declaration so that the name reflects that it's a multi-pack but the quantity is only 1. For example, use "Pack of 500 Paperclips - Qty 1" instead of "Paperclips - Qty 500." |
Shipments lost when you change payment type. |
If you change the payment type, ensure EODs (End of Day forms or manifests) are closed prior to the change, or that day's shipments may be caught in a suspended or unfinished state. |
Error "Rejected by SLM Monitor" when creating a Canada Post label. |
This error occurs when the Canada Post servers throttle your Create Label request. You may also receive this error when there is a Canada Post server maintenance/outage. In either instance, if you receive this error, your best option is to wait a few minutes and try again. Typically, Canada Post allows 20 requests per minute. If you receive this error frequently, you can request a limit increase on your Canada Post account. |
Error "The label for this service cannot be rendered on the type of paper provided." |
The Priority Worldwide services labels are incompatible with ShipStation. To use Priority Worldwide services for a shipment, create the label from the Canada Post portal. To create the label in ShipStation, select a different service. |
