Ontario Affidavit of Identity Template PDF | Download Free
An Ontario Affidavit Template can save time when you need to present sworn evidence, but the details matter more than many people realise. In Ontario, affidavits must be properly sworn or affirmed before a commissioner for taking affidavits and prepared in a format recognised by the court rules, otherwise the document may not be accepted as evidence.
I’ve seen self-represented parties arrive at the Ontario Superior Court of Justice with affidavits they had already signed at home, only to discover the document had to be completed again before it could be used in their proceeding. Whether you’re preparing evidence for a court matter, an LTB dispute, or another legal process, getting the commissioning step right is often where problems arise.
Below you’ll find an Ontario affidavit template, execution requirements, common mistakes to avoid, and practical tips for preparing a document that meets Ontario requirements.

One of the most important Ontario affidavit rules is that the commissioner must actually witness the document being signed. Many people mistakenly sign affidavits in advance, but Ontario law requires the signature to happen in the physical or virtual presence of the commissioner. If this step is skipped, the affidavit can become invalid and rejected by the court or receiving authority.
Ontario also has very detailed affidavit formatting rules compared to many other provinces. Court affidavits often require specific headings, backsheets, jurats, and filing deadlines under the Rules of Civil Procedure. Even small mistakes like leaving out the commissioner’s signature, location, or date can create delays or make the affidavit unusable.
Remote commissioning rules are another major Ontario change. Since 2020, affidavits can legally be signed by video conference, but the affidavit must contain special wording confirming the remote process.
Types of Affidavits in Ontario
Different situations require different affidavits, and choosing the wrong one can lead to rejection or delays. Each type is designed for a specific purpose, so it’s important to understand when to use which document.
Affidavit of Service
An Affidavit of Service (Form 16B) provides sworn proof that litigation documents were delivered in accordance with Rule 16 of the Rules of Civil Procedure.
Operational Trap: Do not use this format for Ontario Landlord and Tenant Board (LTB) matters. The LTB strictly mandates a tribunal-specific ‘Certificate of Service’ form under the LTB Rules of Practice; filing a standard affidavit instead can cause your application to be dismissed for procedural non-compliance.
Affidavit of Identity
An Affidavit of Identity is used to confirm who you are when standard identification documents are not enough. It is often required by banks, travel authorities, or for legal verification purposes where extra proof of identity is needed.
Statutory Declaration (Ontario)
A statutory declaration is similar to an affidavit, but it is not always used in a court setting. Instead, it is commonly used for government forms and administrative processes where you need to declare something as true without going through court procedures.
Court Affidavit (Litigation Affidavit)
A court affidavit is used as evidence in legal cases. It must follow strict formatting rules and is often required under Ontario’s civil procedure rules. Because of its importance in court, accuracy and proper format are very important.
Affidavit of Residency
An Affidavit of Residency is used to confirm your place of residence. It is commonly required for school admissions, immigration purposes, or as proof of address in legal or official matters.
Affidavit of Support
An Affidavit of Support is used to declare that you will financially support another person. This is most commonly used in immigration sponsorship and visa applications, where proof of financial support is required.

Key Elements of a Valid Affidavit in Ontario
Under Ontario law, an affidavit must include certain basic parts to be valid and accepted.
Full Legal Name of the Deponent
Your full legal name should be written exactly as it appears on your official ID. Avoid using nicknames or short forms, as even small differences can cause issues with verification.
Clear Statement of Facts
An affidavit should only contain facts that you know are true. Do not include opinions, guesses, or arguments. Keep your statements simple, clear, and based on real information.
Oath or Affirmation Clause
This section confirms that everything written in the affidavit is true. You can either swear an oath (if you follow a religion) or make an affirmation (if you do not). Both are legally valid in Ontario.
Signature of the Deponent
You must sign the affidavit in front of an authorized person. Do not sign it in advance, as it will not be accepted if it is not properly witnessed.
Commissioner or Notary Signature
A commissioner for taking affidavits or a notary public must watch you sign and then add their signature. Without this step, your affidavit is not legally valid in Ontario.
Different situations require different affidavit types. For identity verification, you may need an affidavit of identity template, while address confirmation may require an proof of residence affidavit. It’s also important to understand the distinction between affidavits and declarations using this affidavit vs statutory declaration comparison.

Legal Overview in Ontario
Under Ontario law:
- Affidavits must be sworn or affirmed before:
- Commissioner for Taking Affidavits
- Notary Public
- They are used as legal evidence in courts
- False statements can lead to perjury charges (serious legal penalties)
- Some affidavits must follow rules under Ontario’s civil procedures (especially court affidavits)
Common Mistakes to Avoid
Many affidavits get rejected because of small and simple errors that can easily be avoided.
- One common mistake is writing opinions instead of facts. An affidavit should only include information that is true and based on your knowledge, not personal views or arguments. Another frequent issue is signing the document before meeting a commissioner. In Ontario, you must sign the affidavit in front of an authorized person, otherwise it will not be accepted.
- Using the wrong type of affidavit is also a major problem. Each affidavit serves a different purpose, so choosing the incorrect one can lead to delays or rejection. Missing important details like your full name, date, or signatures can also make the document incomplete.
- Finally, many people do not follow proper court format rules, especially for litigation affidavits. Even small formatting mistakes can cause issues.
Even simple mistakes like these can make your affidavit invalid, so it’s important to review everything carefully before signing.
