Notify address changes without retyping participant contact details

Cap and trade participants repeat legal entity name, registered address, account representative details, and new mailing information on every Change of Address Notification submitted to the ministry. This guide is an example of storing them once in hivi.

Official form and source

Start from the official source and always use the current version — form numbers and links can change:

• Service page: Cap and trade CITSS registration: update account agent information — ontario.ca
• Form (Central Forms Repository): Change of Address Notification — 012-2131

What this form is about

Form 012-2131 is the Change of Address Notification for cap and trade program participants — confirm CITSS update rules on ontario.ca.

Before you start: what to gather

• Participant legal name and previous address.
• New mailing or registered address details.
• Account representative authorized to notify changes.
• Supporting documentation if director approval is required — confirm on ontario.ca.

How hivi makes it faster

1. Save it once. Store your entity name, address, and representative contact details in your hivi profile.
2. Keep documents ready. Upload supporting documents to hivi Files so you are not searching at form time.
3. Autofill the form. Use the hivi Chrome extension on a web form, or fill a PDF from your saved profile inside hivi.
4. Review and submit yourself through the official channel.
