Notary Public vs Commissioner of Oaths: What’s the Difference and Which One Do You Need?

If you have ever been asked to get a document signed by a Notary Public or Commissioner of Oaths, you are not alone in feeling unsure about which service you actually need. While these roles are often mentioned together, they serve different purposes and are required in different situations.

Understanding the difference can save you time, money, and unnecessary appointments.

What Is a Commissioner of Oaths?

A Commissioner of Oaths is authorized to administer oaths and affirmations for documents that must be sworn or declared to be true. This means the Commissioner verifies your identity and witnesses you swearing or affirming that the contents of a document are accurate.

Commissioner of Oaths services are commonly used for documents such as:

  • Statutory declarations
  • Affidavits for government or administrative purposes
  • Insurance, employment, or benefit forms
  • Certain court or tribunal documents

These documents are typically intended for use within Ontario or Canada and do not usually require notarization.

What Is a Notary Public?

A Notary Public has broader authority and is often required when documents must be recognized as authentic by organizations outside Ontario, outside Canada, or by institutions that require a higher level of verification.

A Notary Public can:

  • Witness and notarize signatures
  • Certify true copies of documents
  • Administer oaths and declarations
  • Notarize documents for domestic or international use

Notary services are commonly required for:

  • Documents being used outside Canada
  • Travel consent letters for children
  • Certified true copies of identification or records
  • Corporate and business documents
  • Immigration or international matters

Why Choosing the Right Service Matters

Using the wrong service can result in your document being rejected, delayed, or needing to be redone. For example, a document that only requires commissioning does not need notarization, while a document being sent overseas may require notarization even if it has already been sworn.

A brief review by a legal professional before signing can help ensure your document meets the correct requirements the first time.

Mobile and Remote Options Make It Easier

Many people assume they must travel to an office during business hours to complete legal documents. Today, that is not always the case. Mobile and remote services, where permitted, allow documents to be commissioned or notarized at your home, office, or through secure virtual processes.

This is especially helpful for busy professionals, families, seniors, and business owners who want minimal disruption to their day.

When in Doubt, Ask First

If you are unsure whether you need a Notary Public or Commissioner of Oaths, it is always best to ask before booking an appointment. A quick review of your document and its intended use can clarify which service is required and help avoid unnecessary steps.
