The Canada Post Shipping Module is a great way to extend your customers shopping experience to include a very sophisticated shipping service. This shipping extension uses the product’s weight and dimensions to calculate the most accurate rates possible using Canada Post’s Sell-Online (http://sellonline.canadapost.ca).

To ensure the accuracy when returning a rate from the Canada Post API it requires, the shipping country, state and Post code/Zip code.


  • This plugin offers a number of shipping methods for both International Shipping and Domestic shipping.
  • You can choose specific shipping Services's to display at the checkout.
  • You can create Custom boxes to suit the size of your products.
  • Using your custom box, you can define the number of items you would like to pack into the custom box and also the maximum weight.
  • You can add a handling fee or add a discount to the Shipping cost.
  • Set a fallback rate, if the Canada Post APi ever goes down, your customers will always be presented with a price.
  • You can re-name the shipping service title's to suit your Website.
  • The product dimensions and weight will be used to pack your items into your Custom Boxes or the pre-defined boxes, once a box has reached it's full capacity (using the dimensions and weight of your
    products), another box will be added. A Box Packaging Algorithm.
  • You can set up as many Customised Boxes as you need to. There is no limit.
  • Select which shipping rates to display at the checkout. Cheapest / Highest / All
  • You can ship with Weight Only- Regular sized items are grouped and quoted by weight only: Product dimensions are still taken into consideration. Not recommended if your products have irregular dimensions or have very large dimensions where dimensional weight will be used to determine the shipping price.
  • We have added a new feature to our WooCommerce shipping extensions, called ‘Order Limit’.We have allowed you to set up a dollar ( ORDER ) amount in the admin area of our extension. When the dollar ( ORDER ) amount is reached in the cart, the ‘Free Shipping’ feature will be available for your customers.

All of our Extensions are developed and Supported by Extension Works, there are no 3rd party developers involved. This will ensure that your request's if any, are handled by Extensions Works in a timely and prompt manner. This we can guarantee.
