The WooCommerce Canada Post Shipping Method is a plugin that allows online merchants to integrate shipping rates and options from Canada Post, a popular postal service in Canada, into their WooCommerce-powered online stores.

With this plugin, customers can easily choose the shipping method they prefer, and merchants can offer additional shipping services such as extra coverage and leaving cards for pickup.

To use this plugin, the online store must use Canadian Dollars as its currency and the server must have SimpleXML installed.

The plugin primarily works with cm and kg, but it can automatically convert other units. The Canada Post Shipping Method plugin can check the availability and costs of the following services:

• Regular Parcel
• Xpresspost
• Priority
• Expedited Parcel
• Priority Worldwide
• Xpresspost USA
• Small Packet USA Air
• Tracked Packet – USA
• Expedited Parcel – USA
• Small Packet International Air
• Tracked Packet – International
• Xpresspost International
• International Parcel – Air
• International Parcel – Surface

The plugin uses the Canada Post Ratings API to get shipping rates, which handles both domestic and international parcels. The plugin also enables merchants to enable or disable, edit the names of, and add costs to these services.

One of the key features of the Canada Post Shipping Method plugin is the built-in box packer, which allows merchants to pack items individually or using boxes.

The packer algorithm finds boxes that fit the items being packed based on their dimensions (height, width, and depth) and uses the smallest box that fits 100% of the items.

If there are unpackable items, the packer will pack them separately using their dimensions. The plugin returns all packed boxes, and merchants can set the packing algorithm to use the highest percentage of packed boxes.

Customers can get quotes for shipping rates from two places after inputting their address: the cart page using the shipping calculator and the checkout page by filling in shipping and billing forms.

Rates can be selected by customers as usual, and merchants can choose to hide the calculator on the cart page by adjusting the Shipping Options.

In summary, the WooCommerce Canada Post Shipping Method plugin is a powerful tool that allows online merchants to integrate shipping rates and options from Canada Post directly into their WooCommerce-powered online stores.

The plugin comes with features such as the built-in box packer, which helps merchants pack items efficiently and enables them to offer additional shipping services to their customers.
