WHAT IS A COMMISSIONER OF OATHS?

What a Commissioner of Oaths Does

A Commissioner of Oaths witnesses sworn statements, administers oaths, and signs affidavits and statutory declarations for use within Ontario. It's a narrower authority than a notary public, a commissioner's signature isn't recognized outside the province, so it only applies to documents staying in Ontario.

Why This Matters If You're Not Sure What You Need

Every notary public in Ontario is also a commissioner of oaths, but the reverse isn't true. Since our team are licensed notaries, you get full notarial authority even for a simple commissioning appointment, so if it turns out your document needs to go further than Ontario, we can handle that too without booking a second appointment elsewhere.

Common Mistakes to Avoid

Assuming a commissioner can certify true copies

In Ontario, certifying a true copy requires a notary public, not just a commissioner of oaths. Since our team are notaries, this isn't a problem with us, but it's worth knowing the distinction.

Using a commissioned document outside Ontario

A commissioner's authority doesn't extend beyond the province. If your document is headed elsewhere, you'll want full notarization instead.

Not having valid photo ID ready

You must be identified before swearing an oath or signing a declaration. Have current, valid government ID on hand.

Signing the document before your appointment

The oath or declaration must be made in front of the commissioner. Wait until your appointment to sign.

COMMISSIONER OF OATHS FAQ

Common Questions

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

A commissioner can witness oaths and sign affidavits for use within Ontario only. A notary public has broader authority, including certifying true copies and notarizing documents for use outside the province. Since our team are notaries, you get the broader authority either way.

Can I do this online?

Yes, most commissioning appointments can be done online by video call, typically in about 15 minutes.

Is a commissioned document valid outside Ontario?

No, a commissioner's authority stops at the Ontario border. If your document is headed elsewhere, let us know and we'll notarize it fully instead.

What do I need for my appointment?

Valid, current government-issued photo ID, and your complete, unsigned document ready to swear and sign in front of us.

Can I combine this with apostille or translation services?

Yes, many clients need a document commissioned, then apostilled or translated. We coordinate the full process for you.
