Most of the activity on our website involves the viewing of materials, which are made accessible to everyone so there is no need for the site to be secure. Other areas of the website require the use of passwords, user IDs and may have other security features. You are responsible to keep your user IDs and passwords confidential. You should promptly notify Canada Post if you become aware of unauthorized use of your user IDs or passwords or use of services or materials available from this site. The use of your user IDs or passwords by you, or by any person with or without your knowledge or consent, in connection with a Canada Post transaction, binds you legally and makes you responsible to the same extent and effect as if you had given signed, written instructions to us, unless you have previously notified us that the confidentiality of your user IDs or passwords has been compromised.
