Thank you so much for sharing some of your feedback about WooCommerce Shipping.
We’re always wanting to improve our products, and we’re currently looking at ways to offer shipping label purchases via WooCommerce Shipping for other carriers—including but not limited to Canada Post.
To help us better determine demand for this feature, I would recommend that you take a couple of minutes and complete this form. This will also allow us to contact you when your requested feature is added.
In the meantime, I would recommend looking at Shippo or ShipStation Integration if you’d like to print Canada Post shipping labels.
I hope this helps! Let us know if you have any further questions!
