Affidavit vs Statutory Declaration Ontario (Differences You Should Know)
Affidavit VS Statutory Declaration Ontario is one of the most confusing legal topics for beginners. Many people think both documents are the same—but under Ontario law, they are used in different situations.
In simple words, both are written statements of truth. But one is sworn under oath, and the other is declared without oath. In my Ontario paralegal work, I’ve seen people submit a statutory declaration when the court or government office actually required a sworn affidavit, and the document was rejected immediately. I know this process can feel confusing the first time, especially when deadlines are involved, but using the wrong document can delay immigration files, court matters, and even provincial applications.
This small difference changes where and how you can use them. In this article, I’ll explain everything clearly—when to use each, legal rules, common mistakes, and give you a free template you can use right away.

| Witness / Commissioner requirement | Documents must be witnessed by a Commissioner for Taking Affidavits or Notary Public. | Commissioners for Taking Affidavits Act, s. 1 |
| Witness qualifications | No additional witnesses are required beyond the commissioner, and the commissioner cannot be a party to the matter. | Common law principles |

Reg. 431/20, and must state the specific city/town and county/region of both the commissioner and the deponent/declarant at the exact time of the audio-visual link. | Commissioners for Taking Affidavits Act, R.S.O. 1990, c. C.17; O. Reg. 431/20, s. 1 (as amended by O. Reg. 21/26) |
| Court filing requirements | Court affidavits must be filed with the Superior Court of Justice or Ontario Court of Justice. | Ontario court filing procedures |

| Absentee commissioning prohibition | A commissioner must actually witness the signing in person or virtually. | Commissioners for Taking Affidavits Act, s. 9 |
| Oath administration requirement | If the commissioner fails to properly administer the oath or affirmation, the affidavit is invalid. | Evidence Act, s. 13 |

| Ontario paralegal authority | Ontario paralegals automatically act as Commissioners for Taking Affidavits by virtue of office. | O. Reg. 386/12 |
| Ontario virtual commissioning system | Ontario permanently adopted virtual commissioning rules instead of temporary emergency measures. | O. Reg. 431/20 |
One of the most important Ontario rules is that affidavits and statutory declarations are not interchangeable. An affidavit must be sworn under oath, while a statutory declaration uses formal declaration wording instead. Using the wrong format can cause courts, immigration offices, or government agencies to reject the document completely.
Another major Ontario-specific rule involves remote commissioning. Ontario permanently legalized virtual signing through O. Reg. 431/20, but the document must clearly state that it was commissioned remotely. Missing this wording may create validity problems later.
These rules matter in real life because affidavits are commonly used in court cases, immigration files, insurance claims, and property matters. Even small technical mistakes — such as signing before meeting the commissioner or failing to administer the oath properly — can make the document invalid and delay important applications or legal proceedings.

In most affidavit situations, courts treat it as serious evidence, while statutory declarations are mainly for administrative or official use..
Affidavits and statutory declarations are both legal statements, but they serve different purposes under Ontario law. To understand how affidavits are structured, you can review the main affidavit template resource.
What Is an Affidavit in Ontario (And When You Need It)
An affidavit is a written document where you state facts and swear they are true. Under Ontario law, this document is treated seriously because it is given under oath.
In most affidavit situations, it is used as evidence. That means judges and lawyers rely on it when making decisions. Because of this, the process must be followed properly.
You will usually need an affidavit in situations like:
- Family law cases such as divorce or child custody
- Civil disputes
- Immigration processes
- Proving facts like identity or events
A commissioner for oaths must watch you sign and confirm your identity. They also make sure you understand what you are signing. If any part of this process is skipped, the affidavit may not be valid.
One important legal point: if you provide false information in an affidavit, it can lead to perjury, which is a criminal offence in Canada. So always be careful and honest.
What Is a Statutory Declaration in Ontario?
A statutory declaration is also a written statement of truth, but you do not take an oath. Instead, you formally declare that the information is correct.
Even though there is no oath, the document still has legal value. Government offices and institutions accept it for many official purposes.
Statutory declarations are commonly used for things like:
- Confirming identity or address
- Replacing lost documents
- Supporting government applications
- Insurance or business declarations
In everyday life, if you are not dealing with a court case but still need to confirm facts officially, this is usually the right document.
Under Rule 39 of the Ontario Rules of Civil Procedure, statutory declarations are inadmissible as evidence-in-chief in court motions or applications due to the rule against hearsay; an affidavit is strictly mandatory. However, administrative tribunals operating under s. 15(1) of the Statutory Powers Procedure Act (such as the LTB) possess wide statutory discretion to admit statutory declarations if they are deemed relevant to the core issue.
When to Use Affidavit vs Statutory Declaration
Choosing between these two depends on the situation. Many people make mistakes here, which leads to rejection or delays.
Use an Affidavit When
You should use an affidavit when your matter involves court or legal proceedings. For example, if you are submitting evidence or your lawyer asks for a sworn statement, an affidavit is required.
Use a Statutory Declaration When
You should use a statutory declaration when there is no court involvement. It is best for confirming facts in government forms, identity verification, or administrative processes.
A simple way to remember:
- Court = Affidavit
- No court = Statutory Declaration
Commissioner of Oaths & Notary Rules in Ontario
Both affidavits and statutory declarations must be signed in front of an authorized person. This step is mandatory.
In Ontario, the following people can handle this:
- Commissioner of Oaths
- Notary Public
- Lawyers (in many cases)
Their job is not to check if your statement is true. Instead, they verify:
- Your identity
- You understand the document
- You are signing willingly
Many people think notarization is always required, but that is not true. In most cases, a commissioner for oaths is enough unless a specific authority asks for notarization.
Key Components That Must Be Included
Every valid document must follow a proper structure. Missing even one key part can make it invalid.
For an affidavit, the document must include a clear title, jurisdiction (Ontario), a sworn statement, numbered facts, and an oath clause. It must also include your signature and the commissioner’s details.
For a statutory declaration, you still need your personal details, a clear statement of truth, a declaration clause, and proper signatures.
The most important thing is clarity. Always write facts in simple sentences and avoid opinions or assumptions.
Common Mistakes That Make These Documents Invalid
From practical experience, many documents get rejected due to small errors. Some of the most common mistakes include:
- Signing the document before meeting the commissioner
- Using the wrong format (affidavit instead of declaration or vice versa)
- Missing required wording like oath or declaration clause
- Providing incorrect or misleading information
- Leaving out important personal details
Even a minor mistake can delay your application or cause legal issues.
Real-Life Examples
Let’s make this simple with real situations.
- If you are filing for divorce or dealing with a court case, you will need an affidavit because it is used as evidence.
- If you lost your ID and need to confirm your identity, a statutory declaration is usually enough.
- In immigration cases, you might need both. Some forms require a sworn affidavit, while others ask for a declaration.
Legal Risks You Should Know
These documents are legally serious. Many people treat them casually, which can cause problems.
If you lie in an affidavit, it is considered perjury and can lead to criminal charges. If you give false information in a statutory declaration, there can still be legal penalties.
Also, using the wrong document or making errors can lead to rejection by courts or authorities. This often results in delays, which can affect your case or application.
How to Fill the Template Correctly (Step-by-Step)
Filling the template correctly is simple if you follow a few basic steps.
- Start by writing only true and clear facts. Use short sentences and number each point properly. Do not add unnecessary details.
- Do not sign the document in advance. Always wait until you are in front of the commissioner or notary.
- Carry a valid ID with you, as it will be required for verification. Before signing, read the document carefully to make sure everything is correct.
- Taking a few extra minutes to review can save you from major problems later.
Affidavits, such as an Ontario sworn affidavit, must be sworn before an authorized official, while declarations follow a different process. If you are preparing either document, it’s useful to understand how notarization works in Ontario.
