I built and maintain a module for Drupal Commerce 1.x that fetches shipping quotes from Canada Post. It is published on drupal.org.
Branch 1.x of the module uses the Canada Post SellOnline API (currently in the process of being retired) and branch 2.x takes advantage of the newer Canada Post Web Services API.
Publishing the module on drupal.org required going through their project application process, which included automated and peer review before being approved.
Features

drupal_http_request()or curl to retrieve rates - multilingual support
