Shopify Canada Post Integration
Nventory bridges Shopify and Canada Post by importing orders into a central dashboard, syncing product data like weights and dimensions, and pushing tracking information back to Shopify once shipments are created in Canada Post.
Sync Matrix
4 data entities in the sync matrix — 1 bidirectional, 3 one-way. Tap any row for details.
Good to Know
Platform restrictions outside any integration tool's control
Label generation must be done through Canada Post's shipping tools, Canada Post APIs, or a dedicated shipping label solution. Nventory syncs the order data and tracking info but does not create labels directly.
Real-time rate calculations require direct integration with Canada Post APIs or Shopify's carrier-calculated shipping feature. Nventory focuses on order and product data sync rather than rate computation.
Delivery times to remote and rural Canadian postal codes can vary significantly from metro estimates, making delivery promises less reliable for non-urban addresses.
Canada Post offers volume discounts through its Solutions for Small Business program. Merchants must enroll separately to access these discounted rates.
Things to Consider
Platform-specific details and how they affect this integration.
Canada Post offers enrolled small businesses volume discounts on Xpresspost, Expedited Parcel, and Regular Parcel. Without enrollment, you pay standard retail rates.
Nventory does not manage Canada Post account enrollment or rate selection, but by syncing accurate product weights and dimensions it ensures the data feeding into your Canada Post shipping workflows is correct.
Who Uses Shopify Canada Post Integration
Common scenarios for connecting Shopify and Canada Post.
How It Works
Nventory sits between your platforms and keeps everything in sync.
Order Flows to Nventory
New Shopify orders sync to Nventory automatically, including line items, weights, dimensions, and the customer shipping address.
Fulfillment Management
Review and manage orders in Nventory's dashboard. Product data including weights and dimensions is available for your Canadian shipping workflow.

Tracking Synced to Shopify
Once the shipment is created in Canada Post, tracking numbers push back to Shopify through Nventory, marking the order as fulfilled and notifying the customer.
Frequently Asked Questions
No. Nventory does not generate shipping labels directly. It syncs order and product data between Shopify and your fulfillment workflow, and pushes tracking numbers back to Shopify after shipments are created in Canada Post through your preferred label solution.
No. Rate calculation is handled by Canada Post APIs or Shopify's carrier-calculated shipping feature. Nventory ensures accurate product weights and dimensions are synced so that rate calculations in other tools are based on correct data.
After a shipment is created in Canada Post, Nventory syncs the tracking number and delivery status back to the corresponding Shopify order, marking it as fulfilled and triggering customer notification emails.
Yes. Nventory imports orders from Shopify and other sales channels into a single dashboard, giving you a unified view of all orders that need Canada Post fulfillment along with their tracking status.
Nventory pushes the Canada Post tracking number to Shopify after the shipment is created, triggering Shopify's customer notification email. Xpresspost and Expedited Parcel services provide detailed scan events including acceptance, in-transit, and delivery. Note that Canada Post lettermail and untracked services do not generate scan events, so only tracked services will show delivery progress to customers.
No. Nventory does not compare carrier rates or select Canada Post services. Rate comparison between Xpresspost, Expedited Parcel, and Regular Parcel requires Shopify's carrier-calculated shipping feature or direct Canada Post API integration. Nventory ensures accurate product weights and dimensions are synced from Shopify so your rate tool has correct data for service-level comparisons.
Verify that your Canada Post API key hasn't expired or been rotated, as expired credentials will silently stop tracking data from flowing into Shopify. Check the parcel status polling frequency in your integration settings — if the polling interval is too long, tracking updates may appear delayed by hours. Also be aware that Canada Post returns tracking data in both English and French, and some integrations may not handle bilingual responses correctly, causing parsing failures that prevent status updates from reaching Shopify.
