Commissioner of Oaths in Canada: What Newcomers Need to Know in 2026

Welcome to Canada! As you embark on your new journey, you will encounter various administrative and legal processes. One term you might hear, and a service you might need, is a Commissioner of Oaths in Canada. Understanding this role is crucial for many newcomers, as it can impact your immigration applications, legal declarations, and more. At WelcomeAide, we are here to simplify these complex topics, ensuring you feel confident and informed every step of the way.

This comprehensive guide will explain what a Commissioner of Oaths does, when you might need one, how to find one, and what to expect during the process. While we project for 2026, the fundamental role and requirements for a Commissioner of Oaths remain consistent, though fees and specific program details from Immigration, Refugees and Citizenship Canada (IRCC) can evolve.

Understanding the Commissioner of Oaths Role

What is a Commissioner of Oaths?

In Canada, a Commissioner of Oaths is an individual authorized by provincial or territorial law to administer oaths, take affirmations, and receive statutory declarations. Essentially, they are empowered to witness your signature on a document and confirm that you have sworn or affirmed the truthfulness of its contents. This process adds a layer of legal validity to your statements.

The Commissioner does not verify the truth of your statements, but rather confirms that you, the signatory, have sworn or affirmed them in their presence. They confirm your identity and that you understand the document's contents before signing.

Key Differences: Commissioner of Oaths vs. Notary Public

This is a common point of confusion for newcomers. While their roles often overlap, there are important distinctions:

• Commissioner of Oaths: Can administer oaths, affirmations, and statutory declarations. They attest to the fact that you swore or affirmed something in their presence.
• Notary Public: Has all the powers of a Commissioner of Oaths, but also possesses additional authority. Notaries can certify true copies of original documents (confirming a copy is identical to the original), verify identities for international documents, and often draft legal documents.

For many immigration-related documents, IRCC will accept declarations sworn before either a Commissioner of Oaths or a Notary Public. However, if you need a "certified true copy" of a document, you will almost certainly need a Notary Public, not just a Commissioner.

Why is this Important for Newcomers?

As a newcomer, you might need to swear an oath or make a statutory declaration for various reasons. These could include:

• Confirming a common-law relationship for immigration purposes.
• Declaring a lost passport or travel document.
• Providing consent for a minor child to travel.
• Attesting to your identity or residency for provincial services.

Having your documents properly sworn or declared by a qualified professional ensures they are legally valid and accepted by Canadian authorities. If you are unsure which documents you need for your immigration process, our WelcomeAide checklist can help you organize everything.

When You Might Need a Commissioner of Oaths

Immigration and Citizenship Applications

Many forms submitted to Immigration, Refugees and Citizenship Canada (IRCC) require a statutory declaration. The most common example is the "Statutory Declaration of Common-Law Union" (IMM 5409). This form is essential for individuals applying as common-law partners in various immigration programs.

Other situations might include:

• Declarations for Lost Documents: If you've lost a crucial document (e.g., birth certificate, marriage certificate) and cannot obtain a new one, IRCC may accept a statutory declaration explaining the circumstances and attesting to the original document's details.
• Declarations of Identity or Residency: In some unique cases, you might need to declare your identity or periods of residency if standard documents are unavailable.
• Parental Consent for Minors: If a minor child is travelling with only one parent or with an adult who is not their parent, a statutory declaration of consent from the absent parent(s) may be required.

Always refer to the specific IRCC application guide for the exact requirements for each form. You can find official forms and guides on the Canada.ca website.

Other Common Scenarios

Beyond immigration, you might need a Commissioner of Oaths for various provincial or personal matters:

• Provincial Government Forms: Some provincial applications, such as those related to health services, driver's licenses, or social assistance, may require a statutory declaration.
• Affidavits for Legal Proceedings: While more common with Notaries or lawyers, some affidavits for court proceedings (especially in small claims court) can be sworn before a Commissioner.
• Insurance Claims: Certain insurance companies might require a sworn statement regarding a claim.
• Declarations of Name Change: In some provinces, a statutory declaration might be part of the legal name change process.

How to Find a Commissioner of Oaths in Canada

Finding a Commissioner of Oaths is generally straightforward in Canada. Here are the most common avenues:

Government Resources

• Provincial Government Websites: Each province and territory maintains a list or a directory of individuals authorized to act as Commissioners of Oaths. For example, in Ontario, you might search the Ministry of the Attorney General's website. In British Columbia, the provincial government website also offers information. It is best to search "[Your Province/Territory] Commissioner of Oaths" to find local resources.
• Members of Parliament (MPs) or Members of Provincial Parliament (MPPs): Many elected officials, or their staff, are commissioners and offer this service to constituents for free. This can be a great, cost-effective option. You can find your local MP by entering your postal code on the Parliament of Canada website.

Legal Professionals

• Lawyers: All lawyers in Canada are automatically Commissioners of Oaths, and many are also Notaries Public. They can administer oaths and make declarations. This is a reliable option, though it typically involves a fee.
• Paralegals (in some provinces): In provinces like Ontario, licensed paralegals can also act as Commissioners of Oaths.

Community Organizations and Other Services

• Settlement Agencies: Many newcomer settlement organizations offer Commissioner of Oaths services, sometimes for free or at a reduced cost, as part of their support for new immigrants.
• Financial Institutions: Some banks may have staff who are Commissioners of Oaths, particularly for internal documents, but this is less common for external personal documents.
• Accountants: In some cases, professional accountants may also hold Commissioner of Oaths designation.

When searching, always confirm if the individual is authorized to act as a Commissioner of Oaths in your specific province or territory.

Preparing for Your Appointment

To ensure a smooth and efficient appointment with a Commissioner of Oaths, preparation is key.

What Documents to Bring

• The Document to be Sworn/Declared: Bring the exact document you need signed. It should be completed, but do NOT sign it beforehand. You must sign it in the presence of the Commissioner.
• Valid Photo Identification: This is absolutely critical. You will need at least one piece of government-issued photo ID, such as a passport, Canadian permanent resident card, or provincial driver's license. The ID must be current and clearly show your photo and signature.
• Any Supporting Documents: If the declaration refers to other documents (e.g., a marriage certificate mentioned in a common-law declaration), it's wise to bring copies, or the originals, for reference, although the Commissioner generally only focuses on the declaration itself.

What to Expect (Identification, Signing Process)

When you meet with the Commissioner of Oaths, the process will typically involve these steps:

1. Identity Verification: The Commissioner will ask for your photo ID to confirm your identity.
2. Review of Document: They will review the document to ensure it is complete and that you understand its contents and the implications of swearing/affirming it.
3. The Oath/Affirmation: You will be asked to verbally swear an oath (referencing a religious text) or make an affirmation (a solemn, non-religious declaration) that the contents of the document are true to the best of your knowledge.
4. Signing: You will then sign the document in the Commissioner's presence.
5. Commissioner's Signature and Seal: The Commissioner will then sign and, if applicable, affix their stamp or seal to the document, indicating that the oath or affirmation was properly administered.

The entire process usually takes only a few minutes once you are prepared.

Typical Fees and Payment

Fees for Commissioner of Oaths services can vary significantly:

• Free Services: As mentioned, your local MP or MPP's office may offer this service for free to constituents. Some settlement agencies also provide it pro bono.
• Lawyers/Paralegals: Expect to pay anywhere from CAD $20 to CAD $50 per signature/document. For more complex documents or multiple copies, the fee might be higher.
• Notary Public: If you specifically need a Notary Public for certified true copies, their fees typically range from CAD $50 to CAD $100 or more per document, depending on complexity and the number of copies.

Always inquire about the fee beforehand to avoid any surprises. Most professionals accept cash, debit, or credit card payments.

Frequently Asked Questions (FAQ)

Can I use a Commissioner of Oaths from my home country?

No, generally not for documents required by Canadian authorities. Documents that need to be sworn or declared for Canadian purposes, especially for IRCC, must be administered by a Commissioner of Oaths or Notary Public authorized to practice in Canada, or at a Canadian embassy, high commission, or consulate abroad by an authorized consular officer. Always confirm the specific requirements with the requesting authority.

How much does it cost to use a Commissioner of Oaths?

The cost typically ranges from CAD $20 to CAD $50 for a simple declaration or oath, but can sometimes be free if obtained through an MP's office or a settlement agency. Notary Public services, which include all Commissioner of Oaths functions plus additional services like certifying true copies, usually cost more, from CAD $50 to CAD $100 or higher.

What if I don't speak English or French well?

It is crucial that you fully understand the document you are signing, as you are swearing to its truthfulness. If you do not understand English or French, you must bring a reliable interpreter with you. The Commissioner of Oaths is required to ensure you comprehend the document's content before administering the oath or affirmation. Some Commissioners may also be fluent in other languages.

Is a Commissioner of Oaths the same as a Notary Public?

No, they are not the same, although their roles overlap. A Commissioner of Oaths can administer oaths, affirmations, and statutory declarations. A Notary Public can do all of these things, plus certify true copies of documents and verify identities for international use. For "certified true copies," you always need a Notary Public.

How long is a sworn document valid?

The validity of a sworn document depends on the purpose for which it was created. For example, a statutory declaration for a common-law relationship should reflect your current status at the time of application. There is no universal expiry date for a sworn document itself, but the information within it must remain current and relevant to the application or situation it supports. Always check the specific requirements of the requesting body, like IRCC, for their validity periods.

Can I swear an oath remotely?

During the COVID-19 pandemic, many jurisdictions temporarily allowed for remote commissioning of oaths and declarations using video conferencing technology. While some provinces have made these changes permanent, or are considering it, the default remains in-person. You must confirm with the specific Commissioner and your provincial regulations if remote commissioning is an option and if it will be accepted by the body requiring the document (e.g., IRCC). For IRCC, in-person signing is generally preferred or required unless explicitly stated otherwise.
