Sign an attestation without retyping your personal details

Ontario attestations repeat your legal name, address, contact information, and signature block on every sworn or affirmed declaration you file with a ministry program. 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: Becoming a commissioner for taking affidavits or notary public — ontario.ca
• Form (Central Forms Repository): Attestation — on00291

What this form is about

Form ON00291 is a general Attestation form used with Ontario government processes — confirm when it applies and who must witness it on ontario.ca.

Before you start: what to gather

• Your full legal name and home or business address.
• Phone number and email if required.
• Statement or facts you are attesting to.
• Commissioner or notary if the process requires witnessing.

Confirm the current process on ontario.ca.

How hivi makes it faster

1. Save it once. Store your name, address, and 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.
