Announcement reposted from Amazon Canada:
To comply with Canadian laws, we have updated the list of information and documentation required to sell on Amazon.ca.
If you’re an Amazon.ca business seller currently selling on the store, you’ll be asked to provide additional business information, such as beneficial owner data, and documentation, such as self-attestation and authorization documents.
No action is required from you until we notify you on your Account Health dashboard to provide this information. This process will begin at the end of January 2025 and continue through the year.
After you submit, we’ll notify you via Seller Central, email, or performance notifications if more information is needed.
You’ll have 60 days after you receive a notification to comply with these requirements. If the required information and documentation isn’t provided within this timeline, your account may be deactivated.
For more information, go to Information required to sell on Amazon.
Professional sellers can contact an account health specialist through the Contact Us link on their Account Health dashboard.
