Many people searching for a notary public and commissioner of oaths in Manitoba are unsure which professional they actually need. While both roles involve witnessing signatures and sworn documents, their authority and permitted use are very different. Understanding the difference between a notary public and commissioner of oaths can save time, prevent document rejection, and ensure your paperwork is legally valid.

Commissioner for Oaths in Manitoba

In Manitoba, a Commissioner for Oaths is certified to witness signatures on affidavits, statutory declarations, and affirmations. It is important to note that a Commissioner for Oaths may only witness documents that are staying within Manitoba.

• Appointment duration: Must be renewed every two years

• Signature requirement: Expiration date must be included under the signature

• Who can hold this title: Lawyers, judges, political representatives, banking employees, and police officers

• Limitations: Cannot certify true copies of documents or notarize for international use

A Commissioner for Oaths is commonly required for local legal forms, affidavits, or applications that will remain in Manitoba.

Notary Public in Manitoba

A Notary Public can also witness affidavits, declarations, and signatures, but with broader authority.

• Global use: Notarizations can be recognized worldwide

• Certified copies: Can certify a true copy of an original document

• Official seal: Uses a stamp or seal when signing documents

• Appointment duration: Does not expire

• Fees: Most lawyers who are notaries charge a small fee for the service

Notaries are ideal when your documents will be used outside Manitoba or require certified copies, such as immigration paperwork, international business contracts, or foreign property transactions.

Key Differences: Notary Public vs Commissioner of Oaths

Both roles do not allow the individual to provide independent legal advice. Lawyers may hold both appointments, but legal advice is separate from notary services.

You may need a Commissioner of Oaths if:
