Canada Post recently went through an infrastructure update on March 10, 2018. Due to this update, your Magento Canada Post Application developed by Demac Media must be updated. Please see the recommended steps below to patch the application.

Steps To Patch Your Magento Canada Post Application:

1. Download the updated module from here: https://info.demacmedia.com/hubfs/demac-canadapost.zip
2. Extract the ZIP contents

If you have access to a developer, we strongly recommend you use them to apply these changes. If not, don’t worry! There are two different approaches you can take here:

Method 1 (Easy):

Copy these files from the extracted folder and overwrite them on your website (where the app folder is):

demac-canadapost/app/code/community/Demac/CanadaPost/etc/cert/cacert.pem

demac-canadapost/app/code/community/Demac/CanadaPost/Model/Adapter/Abstract.php

Method 2 (Hard – For a developer):

Step 1) Update the certificate from the extracted ZIP file: demac-canadapost/app/code/community/Demac/CanadaPost/etc/cert/cacert.pem

Step 2) Apply the following changes to Demac/CanadaPost/Model/Adapter/Abstract.php:

Lines 139 – 143:

$client_options = array(
            'location' => $location,
            'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
            'trace'=>1
        );

TO:

   $client_options = array(
           'location' => $location,
           'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
           'trace' => 1,
           'stream_context' => stream_context_create(
               array(
                   'http' => array(
                       'protocol_version' => 1.0,
                   ),
               )
           ),
        );

Lines 147 – 153:

  $opts = array('ssl' =>
                array(
                    'verify_peer'=> true,
                    'cafile' => $cert,
                    'CN_match' => $this->_location
                )
            );

To:

 $opts = array(
               'ssl' => array(
                   'verify_peer'=> true,
                   'cafile' => $cert,
                   'peer_name' => $this->_location
               ),
               'http' => array(
                   'protocol_version' => 1.0,
               ),
            );
