TL;DR:
- Proper notarization depends on the specific type needed, such as signature witnessing or copy certification.
- Only Ontario Notary Publics can perform full notarizations, while Commissioners for Oaths have limited authority.
- Confirm exact requirements with the requesting party to avoid delays and document rejections.
Choosing the wrong type of notarization for your document in Ontario can cost you more than just time. Immigration applications get rejected. Real estate closings get delayed. Court filings bounce back. The frustrating part is that most people don’t realize there are distinct types of notarization, each with specific legal requirements, until they’re already facing a deadline. Ontario law recognizes several notarization types, and the person authorized to perform them matters just as much as the process itself. This guide breaks down every type, who can perform it, and how to choose correctly the first time.

Understanding notarization: What it means in Ontario
Notarization in Ontario is a formal legal process where an authorized official verifies the authenticity of a document, confirms the identity of the person signing, and in some cases administers an oath. It is not simply a stamp. The process carries legal weight and is recognized by courts, government agencies, and foreign institutions.
Two main types of officials can perform notarization-related services in Ontario:
- Notary Public: A lawyer or paralegal appointed under Ontario law with broad authority to certify documents, witness signatures, administer oaths, and authenticate documents for international use.
- Commissioner for Oaths: Has narrower authority, limited mainly to administering oaths and taking affidavits. Cannot certify true copies or handle international documents.
The distinction matters enormously. Under the Notaries Act (RSO 1990, c N.6), a Notary Public holds broader powers than a Commissioner for Oaths, including the authority to certify copies of documents and prepare documents for use abroad.
“A Notary Public in Ontario can perform every function a Commissioner for Oaths can, but the reverse is not true. Submitting a document requiring notarization to a Commissioner instead will result in rejection.”
Understanding what a notary does in practical terms helps you ask the right questions before you book an appointment. A Notary Public witnesses and certifies signatures, certifies true copies of original documents, and administers oaths and statutory declarations. They also verify that the person signing is doing so voluntarily and has the legal capacity to do so.
Knowing the Ontario notary requirements for your specific document type protects you from costly mistakes. If the requesting party, such as a foreign embassy or a court, specifies a Notary Public, a Commissioner for Oaths simply will not do.
Types of document notarization in Ontario
With that foundation, let’s break down the specific types of document notarization you might need in Ontario. The Notaries Act (RSO 1990, c N.6) outlines three core notarization types performed by a Notary Public.
Witnessing or certifying signatures: The Notary confirms your identity, watches you sign, and certifies that the signature is genuine. This is common for contracts, powers of attorney, legal forms, and financial agreements. The Notary is not verifying the content of the document, only the authenticity of the signature.
Certifying true copies: The Notary compares a copy to the original document and certifies they are identical. Passports, academic transcripts, immigration documents, and professional licenses frequently require certified true copies. The original must be presented in person.
Administering oaths, affirmations, and statutory declarations: The Notary administers a formal oath or affirmation before the person signs a sworn statement. This applies to types of affidavits used in court, government submissions, and business filings. A statutory declaration guide can help you understand when a declaration is required versus an affidavit.
There is also an important edge case: Notaries in Ontario can prepare and certify documents intended for use in foreign countries, including adding an apostille or coordinating authentication. This is a function completely outside the scope of a Commissioner for Oaths.
Understanding the purpose of statutory declaration helps clarify when this type of notarization is the right choice versus a simple witnessed signature.
“Each notarization type serves a distinct legal function. Using the wrong one is like filing the wrong tax form. The paperwork looks complete, but it will be rejected.”
Pro Tip: Before booking any notary appointment, contact the requesting party (the court, embassy, or institution) and ask specifically which type of notarization they require. This single step prevents most rejections.
The notarization process: Step-by-step in Ontario
Once you know what notarization you need, here’s how to get your document properly notarized in Ontario, step by step. The Notaries Act (RSO 1990, c N.6) sets out requirements including in-person verification, ID review, and document completeness checks.
- Prepare your document: Bring the original, unsigned document. Never sign before the appointment. Pre-signed documents are one of the most common reasons notarizations fail.
- Bring valid government-issued photo ID: A passport, driver’s license, or provincial ID card is required. The name on your ID must match the name on the document exactly.
- Present the original (if certifying a copy): The Notary must see the original document to certify a copy. Photocopies of originals are not acceptable.
- Sign in the Notary’s presence: The Notary watches you sign and may administer an oath if required.
- Notary applies seal and signature: The official seal and signature complete the process and make the document legally recognized.
Knowing how to notarize in Ontario ahead of time saves you from wasted trips. Fees typically range from $20 to $80 per document, depending on the type and the notary’s office. Review notary requirements and confirm what ID is needed for notary in 2026 before your appointment.
| What to bring | What to expect |
|---|---|
| Original unsigned document | Identity verification |
| Government-issued photo ID | Review of document completeness |
| Original documents (for copy certification) | Oath or affirmation if required |
| Payment ($20 to $80 typical) | Notary seal and signature applied |
| Instructions from requesting party | Confirmation of document purpose |
Pro Tip: Book your appointment at least a few days in advance and email the Notary your document beforehand. Many offices will flag issues before you arrive, saving you a second trip.
Special situations: Remote and international notarization
Not all notarizations are for domestic use, and not all can be done online. Here’s what to know about remote and international situations.
First, a common misconception: Ontario does not permit full online notarization process the way some U.S. states do. Under the Notaries Act (RSO 1990, c N.6), remote notarization is not permitted in Ontario. What is allowed since 2020 is remote commissioning of oaths and affidavits under specific regulations.
| Feature | In-person notarization | Remote commissioning |
|---|---|---|
| Signature witnessing | Yes | No |
| Certified true copies | Yes | No |
| Oaths and affidavits | Yes | Yes (specific cases) |
| International documents | Yes | No |
| Statutory declarations | Yes | Limited |
“Remote commissioning is a helpful option for certain affidavits, but it is not a substitute for full notarization. Sending a document abroad? You will need in-person service.”
For international use, the process depends on the destination country:
- Hague Convention countries: As of 2024, Ontario issues apostilles, replacing the older authentication process. This is a significant change for anyone sending documents to countries like France, Germany, or Mexico.
- Non-Hague countries: Documents require a full authentication chain through Global Affairs Canada.
- Translation requirements: Some countries also require a regulated translation workflow alongside notarization.
For document authentication questions or guidance on legalizing documents for foreign use, confirm the destination country’s requirements before you start the process. Getting this wrong can mean starting from scratch.
A practical take: Choosing the right notarization for your needs
Here’s something most guides won’t tell you: the biggest source of notarization errors in Ontario isn’t fraud or incompetence. It’s assumption. People assume any notary can handle any document. They assume online means fully remote. They assume a Commissioner for Oaths is equivalent to a Notary Public. None of these are true.
We’ve seen clients arrive with documents pre-signed, without ID, or needing an apostille when they only booked a basic signature witnessing. Every one of those situations creates delays that could have been avoided with one phone call.
The difference between legalization vs notarization alone trips up a surprising number of people. Notarization confirms authenticity within Canada. Legalization or apostille is what makes that document valid abroad. They are not the same step.
Smart users ask three questions before booking: Do I need a notarized signature, a certified copy, or a sworn declaration? Is this document for domestic or international use? Does the requesting party specifically require a Notary Public or will a Commissioner for Oaths suffice?
Pro Tip: Always confirm with the receiving institution exactly what they need before you book. A two-minute email or phone call can save you days of delays and the cost of a second appointment.
