A person may be asked to sign a formal statement in many ordinary situations. An immigration officer may need an explanation about a missing document. A government form may ask for a statutory declaration. A school, bank, employer or foreign authority may request a sworn statement. A real estate or business document may include a declaration that certain facts are true.
The document may look simple. The language may be short. The appointment may take only a few minutes. Still, an affidavit or statutory declaration is not just a signed letter with a stamp.
When you sign this type of document, you are formally confirming that the information is true. In Ontario, this is usually done before a commissioner for taking affidavits or a notary public. The official role is not to make your statement true. The role is to administer the oath, affirmation or declaration and confirm that the document was signed through the proper process.
This article continues our series on notary and commissioner services in Ontario. If you are not sure whether you need a notary public or a commissioner for taking affidavits, start with our guide: Notary Public or Commissioner in Ontario: What Do You Need? The focus here is narrower: affidavits, statutory declarations and the practical meaning of signing one.
What Is an Affidavit?
An affidavit is a written statement of facts that a person swears or affirms to be true. The person who signs the affidavit is often called the deponent.
Affidavits are used when a formal statement is needed for a legal, administrative or official purpose. Depending on the situation, an affidavit may be used in court matters, immigration applications, real estate files, business records, identity issues, lost document explanations or other processes where a regular letter may not be enough.
The important point is that an affidavit is not only about writing something down. It also includes a formal step. The deponent must swear or affirm that the contents are true before a person authorized to take affidavits, such as a commissioner for taking affidavits or a notary public.
Swearing and Affirming
When a person swears an affidavit, they make a formal promise that the contents are true. Some people prefer not to swear an oath for personal, religious or other reasons. In that case, they may affirm instead.
An affirmation serves the same practical purpose as an oath. The person is still formally confirming that the contents of the affidavit are true. The difference is in the form of the promise, not in the seriousness of the document.
What Is a Statutory Declaration?
A statutory declaration is also a formal written statement of facts. The person signing it solemnly declares that the information is true.
Statutory declarations are often used when a formal confirmation is needed, but the document does not need to be sworn as an affidavit. They appear in many administrative, immigration, government and private processes.
A statutory declaration may be used to confirm identity details, explain a discrepancy in personal information, declare a relationship, confirm the loss of a document or support an application where the receiving organization requires a formal declaration.
The person signing a statutory declaration is usually called the declarant. Like an affidavit, the declaration must be made before an authorized person.
Affidavit or Statutory Declaration: What Is the Difference?
For many clients, the practical difference is not obvious because both documents are formal statements of truth. The safest answer is usually found in the instructions from the organization requesting the document.
If a form says “affidavit,” do not replace it with a statutory declaration unless the receiving organization confirms that this is acceptable. If a form says “statutory declaration,” do not assume that any notarized letter will be enough.
The difference often depends on the legal or administrative process involved. Some processes require an affidavit because the statement is being used in a court or legal setting. Other processes use statutory declarations because the person must formally declare facts for a government, immigration, business or administrative purpose.
The wording matters. A commissioner or notary can help complete the formal signing step, but the receiving authority decides what type of document it will accept.
What the Commissioner or Notary Checks
When you sign an affidavit or statutory declaration, the commissioner or notary is not simply adding a stamp. They must follow a proper process.
The process usually includes confirming your identity, making sure you are the person signing the document, administering the oath, affirmation or declaration, and confirming that you signed the document in their presence, whether in person or through a permitted remote commissioning process.
You should bring valid government-issued identification. If the document refers to another name, a changed name or a spelling difference, bring supporting documents if available. The person administering the document may need to understand why the identification and document do not match exactly.
The commissioner or notary also checks that the document is complete enough to be signed. Blank spaces, missing pages, unsigned attachments or unclear wording can create problems. If the document is incomplete, you may be asked to correct it before signing.
What the Commissioner or Notary Does Not Confirm
A common misunderstanding is that a commissioner or notary confirms that the entire document is factually true. That is not the role.
The person signing the affidavit or declaration is responsible for the truth of the statement. The commissioner or notary administers the formal step and confirms that the oath, affirmation or declaration was made properly.
The commissioner or notary also does not automatically confirm that the document is legally suitable, that it will be accepted by the receiving authority, or that the wording protects your interests. If the document was prepared by someone else, if it affects your rights, or if you do not understand its consequences, you may need legal advice before signing.
This is especially important for immigration, real estate, family, estate, business and financial documents. A statement may look harmless, but the wording can still affect an application, transaction or legal position.
Signing Before the Appointment
Many affidavits and statutory declarations must be signed in front of the commissioner or notary. Signing too early can make the process more complicated.
If the document requires the official to confirm that it was sworn, affirmed or declared before them, the signature should usually happen during the appointment. If you already signed the document, you may need to print a fresh copy and sign again in the proper way.
Before the appointment, you can review the document, gather supporting materials and prepare your identification. Unless you have been specifically instructed otherwise, do not sign the affidavit or statutory declaration in advance.
Remote Commissioning in Ontario
Ontario allows oaths and declarations to be administered remotely if the requirements under Ontario Regulation 431/20 are met.
Remote commissioning is not the same as simply sending a signed scan by email. The process must allow the commissioner or notary and the deponent or declarant to see, hear and communicate with each other in real time throughout the transaction. Identification, document review and signing steps must be handled properly.
Remote commissioning can be useful for people who cannot attend an office in person, but it is not always the right choice. Some receiving organizations may still require original ink signatures, in-person signing or specific wording. A document for use outside Canada may also have additional requirements.
Before choosing a remote appointment, check whether the organization receiving the document will accept a remotely commissioned version. If the instructions are unclear, ask before signing.
Common Reasons People Need Affidavits or Declarations
Affidavits and statutory declarations are used in many settings. The exact wording depends on the purpose, but the underlying idea is the same: a person is formally confirming facts.
Immigration and Status Documents
Immigration matters may require affidavits or declarations when a person needs to explain missing documents, name differences, relationship history, family circumstances, employment history or other facts relevant to an application.
This does not mean that every personal letter should be notarized. It also does not mean that notarization guarantees acceptance by Immigration, Refugees and Citizenship Canada. Immigration documents must be prepared according to the program requirements and the facts of the case.
A later article in this series will focus on notarized documents for immigration applications in Canada, including translator affidavits, certified copies and common document issues.
Identity and Name Differences
A declaration may be needed when documents show different versions of a name, different spelling, a previous name or a missing middle name. These situations are common for people who have documents from different countries, different languages or different stages of life.
The declaration should explain the discrepancy clearly and honestly. It should not be used to cover a problem that needs official correction through the issuing authority.
Lost or Unavailable Documents
A person may need to declare that a document was lost, stolen, destroyed or cannot be obtained. This type of statement must be careful. It should explain what happened, what steps were taken to find or replace the document, and why the document is unavailable.
The declaration does not replace the original document in every situation. The receiving organization decides whether the explanation is enough.
Business and Administrative Documents
Businesses may use affidavits or declarations to confirm signing authority, corporate facts, licensing details, address information or other administrative matters.
If the statement affects corporate rights, shareholder interests, financial obligations or a transaction, legal review may be needed before signing. A commissioner or notary can help with the formal declaration, but that does not replace advice about the business consequences.
Common Mistakes That Cause Problems
The most common mistake is treating an affidavit or declaration as a routine formality. The document may be short, but the statement can still have consequences.
Another mistake is using vague language. A declaration that says “I confirm everything is correct” may not be helpful if the receiving organization needs specific facts, dates, names or explanations.
Some people sign before the appointment, bring only a photo of their identification, forget supporting documents or send an incomplete file. Others assume that a stamp will fix weak wording or missing evidence.
A stamp cannot repair an inaccurate statement. It cannot turn a vague explanation into strong evidence. It cannot make the receiving authority accept a document that does not meet its instructions.
How to Prepare the Document
Before booking an appointment, read the instructions from the organization requesting the affidavit or declaration. Check whether it asks for an affidavit, statutory declaration, certified copy, notarized signature or another type of document.
Prepare the full document before the appointment, but do not sign it unless instructed. Use names, dates and facts consistently. If the statement refers to attachments, bring the attachments. If the declaration explains a missing document or name discrepancy, bring any available proof that supports the explanation.
Bring valid government-issued identification and make sure the name on your identification can be connected to the name in the document. If there is a difference, mention it before the signing starts.
If the document will be used outside Canada, or if the receiving authority has special instructions, bring those instructions with you. Some documents may require additional steps after notarization or commissioning. That topic will be addressed in our article on apostille and legalization in Ontario.
When Legal Advice May Be Needed
Not every affidavit or statutory declaration requires legal advice. Many documents are straightforward. However, some statements should be reviewed before signing.
You should consider legal advice if the document affects immigration status, property, money, family rights, business authority, liability, court matters or any disputed facts. You should also be cautious if someone else prepared the document and asks you to “just sign it.”
The role of legal advice is different from the role of commissioning. Commissioning confirms the formal act of swearing, affirming or declaring. Legal advice helps you understand whether the document should be signed, whether the wording is appropriate and whether the statement may create risk.
Practical Takeaway
An affidavit or statutory declaration should be treated as a formal statement, not as a casual note with a stamp. The person signing is responsible for the truth of the contents. The commissioner or notary helps complete the official process, but they do not guarantee that the document will be accepted or that the wording is legally safe.
