Offer Canada Post Lettermail & Parcel Services in WooCommerce
To offer Canada Post Lettermail and Parcel Services in WooCommerce, you can use the Canada Post Shipping Plugin for WooCommerce.
To get started with the plugin, visit the following guide: Canada Post Shipping Guide for WooCommerce.
Once the plugin is configured, you can set up Lettermail for small, lightweight items.
- Lettermail is available for domestic shipments.

- While Letter-Post covers international shipments.

Although the shipping costs for these services are predefined, the plugin provides flexibility to adjust the rates as per your requirements for both Lettermail and Letter-Post.

For larger or heavier shipments, you can enable Parcel Services in the plugin’s settings.

Based on your configuration, live rates will appear at checkout. For products eligible for Lettermail, those rates will be shown; otherwise, parcel service rates will appear if you have enabled them.

In addition, the plugin allows you to generate and print Canada Post shipping labels for Parcel Services directly from your WooCommerce orders.

Real-World Scenario: WooCommerce Store Using Lettermail & Parcel Services
A Canadian WooCommerce store sells handmade greeting cards and small stationery items. Most of its domestic orders weigh less than 50 g and fit within the standard letter size.
To keep shipping costs low, the store integrates the Canada Post Shipping Plugin to get Lettermail rates.
At checkout, customers purchasing a few cards automatically see Lettermail rates such as $1.44 or $1.75 based on weight. When a customer adds multiple items that exceed the letter size or weight limit, the plugin seamlessly switches to Parcel Services like Regular Parcel or Expedited Parcel.
The store owner can:
- Offer affordable shipping for lightweight domestic and international orders using Lettermail or Letter-Post.
- Provide real-time parcel rates for heavier packages with tracking and delivery confirmation.
- Print and attach Canada Post Parcel labels directly from the WooCommerce dashboard.
