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.
Topic summary
Main issue: Connecting a Canada Post account to Shopify only displays negotiated rates at checkout; labels bought in Shopify use Shopify’s rates/account and do not contribute to a merchant’s Canada Post discount tiers. Merchants request that labels be purchased under their own Canada Post accounts.
Shopify response: Feedback forwarded; no timeline or commitment. “Carrier-calculated shipping” (CCS) shows your rates at checkout, but label purchasing still uses Shopify Shipping. Earlier guidance said CCS could be added to standard plans for $20/month or free on annual billing, but a 2023 report says this is no longer available and requires upgrading to a higher plan (and possibly paying the add-on).
Workarounds adopted: Third‑party apps that buy labels on your Canada Post account so shipments count toward tiers:
- ShipStation (monthly fee; auto-fulfills; remember end-of-day or $1/package fee).
- Shippo/GoShippo (per‑label fee; multi‑carrier; auto-sync/fulfill).
- Multi Carrier Shipping Label (bulk labels, pickups; mixed UX feedback).
Other concerns: Taxes at checkout (HST/PST) appear misapplied for interprovincial orders; Shopify bills labels in USD; rate parity varies by plan.
Status: Unresolved. Merchants rely on apps; plan/CCS availability remains inconsistent.
