Frequently Asked Questions

What’s the difference between a notary and a commissioner of oaths?

All Ontario notaries are commissioners, but not all commissioners are notaries. Notaries can also certify copies, certify signatures, and notarize documents for international use.

Do I need a notary or a commissioner?

If you only need an oath on a Canadian affidavit, a commissioner is enough. If your document is going outside Ontario, or you need certified copies, you need a notary.
