Hi, @Ironworks .
Sophia here from Shopify. Thank you for taking the time to share your experience here. I want to assure you that this feature request has been submitted to our developers for consideration in future updates.
While I can’t guarantee when and if Canada Post manifests will be available directly through the admin, I’m happy to discuss the other options with you in the meantime, especially if there’s an app that’s more cost effective for your business. I was taking a look at the Canada Post website where they’ve listed several apps to help you integrate your Canada Post features with Shopify.
Shippo is included in that list, and I know it’s a popular option for many merchants here. Shippo has more details about how to create manifests with their app here: Manifests and SCAN Forms. I also came across Multi Carrier Shipping Label in the Shopify App Store. Are either of these the app that you’re currently using?
I understand that using a paid app isn’t an ideal solution for you. While these apps are a workaround for now, our developers are reviewing your feedback and you can keep an eye out for future updates on the changelog.
