Linking your Canada Post account with shopify

87 1 71
Quite disappointed to learn that when I linked my Canada Post small business account to my Shopify, my shipments don't contribute to my savings level increasing. Shopify only USES my current rate. My shipments don't contribute to my ACTUAL CP account.

@Flow13 It might be possible with a shipping app, like Multi Carrier Shipping Label? 

Note that 'connecting' your CPC account only displays your prices. If you click the "print shipping label" option in Shopify, it will charge you the Shopify pricing/labels, not apply it to your account. (But you can do it with a third party app like MCSL... long story short, the Canada Post integration sucks and you should find an app that does what you want)

Yes, as @chcsep has mentioned, you might face issues with printing labels using your own Canada Post account directly from Shopify. There has been some of the other threads mentioning similar issues.

Our Multi Carrier Shipping Label app is a go-to solution for automating the complete shipping process with Canada Post. You can get negotiated rates, print shipping labels in bulk and also automate the tracking process. You can try the app with a 14-day free trial and let us know if you have any other specific requirement.

I hope this helps!

Is there any update on this integration?  We have a substantial discount with Canada Post already (higher than yours) which means we have to manually generate the label on Canada Post and then come back to message the customer when we ship.

I'm currently purchasing labels with Canada Post in commercial tier 8, and using shipstation integration with Shopify. 


Jump into shipstation, refresh it, print your labels and it automatically updates and closes out the Shopify order. 


All you have to do is remember to do your end of day every day or they (Canada Post) charge you $1 per package that you forget to do end of day for.

Hey Flow 13,

You can pay an extra $20 per month to them for the privilege of using 3rd party carriers. You need to call in for this option, as they don’t advertise it at all. 
Alternatively you can upgrade to the next tier, but it’s cheaper to just add-on third party carrier rates.

Hi, everyone!

Sophia here from Shopify. I really appreciate you all continuing to share your experiences, questions, and feedback here regarding how Shopify integrates with Canada Post. This allows me to forward concerns and feature requests to our developers and our Shipping team.

While I can't guarantee which changes will be made and when, I can ensure that our developers receive your feedback and specific use cases for consideration in future updates. In the meantime, I'd like to review the options that are currently available that have been mentioned throughout this thread.

Shopify Shipping

Shopify Shipping allows you to use Shopify's discounted rates with Canada Post to display to customers at checkout, and use to purchase labels directly in the admin. This feature is available on all standard plans, so there is no additional cost other than the cost of purchasing labels. Details including available shipping services can be found here: Shopify Shipping with Canada Post.

Carrier-calculated shipping

Carrier-calculated shipping allows you to connect your own Canada Post account in order to display your negotiated rates to customers at checkout. This feature is included in the Advanced Shopify and Shopify Plus plans, and can be added to any of the standard plans for $20 USD/month. Alternatively, the carrier-calculated shipping feature can be included for free if you are on an annual, biennial, or triennial plan rather than a monthly subscription. To add this feature to a standard plan, please contact us through the Shopify Help Center.

Third-party apps

Carrier-calculated shipping can connect your negotiated rates to Shopify, but it does not currently support label purchasing with your rates. This means that labels purchased in the admin will use Shopify Shipping rates. As others have mentioned in this thread, you can use a third-party app to purchase Canada Post labels, allowing your purchases to be reflected in your Canada Post account so that you can negotiate new rates based on your purchase volume. These are the apps that merchants in this thread have noted they use:

The first two apps here offer free trials, and the third is free to install (though charges may apply depending on your label purchases). You can view the other third-party shipping apps here in the Shopify App Store.

Any platform updates or feature releases will be posted on the Shopify Changelog. If you have any questions about the current options or any specific use cases you'd like to share with our developers, please let me know. Thank you!

Quite disappointed that this issue still hasn't been resolved with Shopify. It only seems logical for them to offer this feature since they allow you to display negotiated rates to customers.
