Commerce Canada Post

This module provides Canada Post shipping quotes for Drupal Commerce.
The 7.x-1.x branch supports the SellOnline API. This API is being retired but should work for all of 2013.
The 7.x-2.x branch supports the new Canada Post web services API.

Requirements

7.x-1.x Branch

7.x-2.x Branch

Installation and Configuration

Once installed, browse to Administration > Store Settings > Advanced store settings > Shipping to edit the settings. Canada Post shipping services (Expedited, Xpresspost, etc) can be enabled/disabled from this form in addition to changing basic settings like turnaround time, origin postal code, and markup/handling rates (for the 7.x-1.x branch, these will override the settings in your Canada Post Sell Online account).
You will also need to add a physical weight field (from the Physical Fields module) to your product variation types and supply weight values for your products. If no weight can be determined for an order, the module will not return any shipping rates. The name of the weight field does not matter.

Notes when upgrading from 7.x-1.x to 7.x-2.x

Upgrading to 2.x will require re-selecting available shipping services.
