What is the difference between a notary and a commissioner of oaths?

A commissioner of oaths administers oaths, affirmations and declarations, typically for documents used in Ontario. A notary public can do the same and can also certify copies and notarize signatures, which is often what institutions and foreign governments ask for. We can tell you which your document needs.

Using a document outside Canada?

Some countries need more than a notarization. Canada joined the Hague Apostille Convention on January 11, 2024, so documents for other member countries can be apostilled — in Ontario, through the province’s Official Documents Services. Check the receiving country’s requirements before your appointment and we will prepare the document accordingly.

FAQ

Notary Public questions

General information about Ontario law, not legal advice for your situation.

What do I need to bring to a notary appointment?

Valid, unexpired government-issued photo ID, and the document itself — unsigned, because it must be signed in front of the notary or commissioner. If others need to sign, they must attend with their own ID.

Do I need an appointment?

Yes, please book ahead by phone or WhatsApp so a notary or commissioner is available when you arrive.

Can you notarize a travel consent letter for my child?

Yes. A consent letter, signed by the parent(s) not travelling and witnessed, is recommended by the Government of Canada when a child travels abroad without one or both parents.
