Key Takeaways

  • A Notary Public helps to prevent fraud and authenticates true copies of documents.

A notary public is someone who is authorized to witness the signing of important documents and administer oaths. In some cases, a notary may also be a lawyer, paralegal, or law student.

The primary purpose of a notary public is to prevent fraud by:

  • verifying the identity of the person signing the document
  • ensuring that the person understands the nature of the document they’re signing 
  • ensuring that the person is if sound mind and is signing willingly

You’ll frequently find notaries involved in real estate transactions, Wills and Estates, and other legal matters where it is important to have an impartial witness to the signing of a particular document.

Usually, a notary public will also be required to stamp or seal the document with an official notary seal.

Why Do Some Documents Need to be Notarized?

There are several reasons why a document may require the signature of a notary public. 

  • Identity Verification 

The main reason documents require a notarization is to provide evidence that the signer is who they say they are. This is especially important if the document involves a significant financial transaction, like a real estate closing, or if it is being used as part of a legal proceeding.

  • Assessing Capacity 

A lesser-mentioned, but equally important, reason to have a notary witness someone’s signature is to ensure that they understand what they’re signing, and are doing so under their own free will. A notary public can ask the person to swear or affirm that they are signing the document without being coerced by another person. 

  • Authenticating a Document 

Finally, a notary public may be required to authenticate a document with their signature and seal. This is especially important if the document needs to be presented in a different jurisdiction, as the notary’s signature and seal can provide evidence that the document is genuine. This is often seen with immigration documents during a process called Authentication and Legalization, or with documents like Travel Consent Letters.

What Documents Must be Notarized?

Notary publics are authorized to notarize a wide variety of documents including: Statutory Declarations, Affidavits, and Powers of Attorney.

In general, a notary public can notarize any document that requires an official witness to the signing of the document.

However, there may be some restrictions on what types of documents a notary is authorized to notarize depending on which province they’re located in. Before your appointment, it’s a good idea to confirm that your particular document can be notarized.

Our services are performed by licensed legal professionals, including commissioners for taking affidavits and other authorized professionals, who are duly authorized to administer oaths, affirmations, and statutory declarations in accordance with the Commissioners for Taking Affidavits Act (Ontario) and related provincial legislation.

Online or remote notarization is not yet explicitly regulated under Ontario law. As a result, NotaryPro does not provide online notarial services, including the digital notarization of documents. Any references on our platform to terms such as ""notary,"" ""online notary,"" ""notarize online,"" or similar expressions are used strictly in an informal and descriptive manner. These references relate exclusively to our legally recognized remote/virtual commissioning and virtual witnessing services, which are distinct from notarial acts.

NotaryPro is not a law firm and does not provide legal advice, legal representation, or legal opinions. While we facilitate virtual commissioning and virtual witnessing services, we do not offer legal guidance on the validity, enforceability, or acceptance of documents by third parties.

If you require legal advice regarding the execution, validity, or use of a document, we strongly recommend consulting a qualified lawyer or other legal professionals. Additionally, before proceeding with virtual commissioning, virtual witnessing, or electronic document execution, it is advisable to verify acceptance with the intended recipient(s), such as courts, government agencies, or other institutions.
