Notary public in Toronto certifying a document
Overview

What a commissioner of oaths does in Ontario

Short answer: A commissioner for taking affidavits, usually called a commissioner of oaths, administers the oath, affirmation or declaration on an affidavit or statutory declaration and signs the jurat that records where and when it was sworn. Every Ontario lawyer and licensed paralegal is a commissioner by virtue of their licence. You sign the document in front of the commissioner, with photo ID, after swearing or affirming that its contents are true.

Civitas Law is a team of legal professionals under the leadership of lawyer Nasibeh Mehrpouyan, a lawyer who is both a commissioner for taking affidavits and a notary public. We commission affidavits and statutory declarations for Ontario courts, tribunals, government offices, banks, insurers and immigration applications, in English, French, Farsi, Russian and Serbian, at 4789 Yonge Street, Suite 402, at Yonge and Sheppard in North York.

The commissioner's job is limited and important. The commissioner confirms who you are, makes sure you understand what you are signing, administers the oath or declaration in a way that binds your conscience, and signs the jurat. The commissioner does not confirm that what you say is true; you do, under oath, and the law treats a false statement seriously.

If your document is going to another country or the office asks for a notarized document or a certified copy, you need a notary public rather than a commissioner. Our notary public page explains the difference, and our certified true copy page covers copies.

Who can commission

Who can be a commissioner of oaths in Ontario?

Ontario's Commissioners for Taking Affidavits Act and its regulation create two groups:

  • Commissioners by virtue of office. Lawyers and licensed paralegals are commissioners because of their licence. As of November 2026 the regulation also lists judges, justices of the peace, members of the provincial legislature and their constituency staff for constituent work, municipal clerks, ServiceOntario staff while serving the public, and police officers only as part of their duties.
  • Appointed commissioners. Other people can be appointed by the province, usually for their employer's purposes, with limits shown on an approved stamp. Appointments made on or after January 1, 2026 run for 10 years and can be renewed.

Notaries public can do everything a commissioner can do. Commissioners cannot take their own affidavits, must not give legal advice unless they are lawyers or paralegals, and an appointed commissioner cannot act after the expiry date on their stamp. Whether a particular government office will commission your type of document is up to that office.

Two documents

Affidavit or statutory declaration: what is the difference?

Both are written statements of fact that you confirm before a commissioner. The difference is mostly about where they are used and the words of confirmation.

  • An affidavit is sworn or affirmed, usually as evidence in a court or tribunal proceeding. In Ontario civil cases, rule 4.06 of the Rules of Civil Procedure sets the format, including exhibits, alterations and affidavits sworn through an interpreter. The Family Law Rules have their own affidavit forms.
  • A statutory declaration is a solemn declaration, usually for a government office, bank, insurer or other organization outside of a lawsuit. The declarant states that they make it "conscientiously believing it to be true" and knowing it has the same force and effect as if made under oath. Ontario's Evidence Act covers declarations under Ontario law, and section 41 of the federal Canada Evidence Act covers federal ones.

Common statutory declarations include declarations of common-law union and marital status for immigration, lost document and identity declarations, declarations for insurance claims and estate matters, and declarations of facts for banks and registries. If an office gives you its own form, use that form and do not change its wording.

Oath or affirmation

Swearing an oath or making a solemn affirmation

Under Ontario's Evidence Act, an oath or affirmation must be one the person declares binding on their conscience. You can swear on a religious text of your choice, swear without one, or make a solemn affirmation with no religious content. All carry the same legal weight, and you should never be pressured to choose one over another. You can bring your own religious text if you prefer.

The commissioner asks you to confirm that the contents of the document are true, and you answer aloud. Many commissioners then ask whether you consider yourself bound by the oath or affirmation. Only after that does the commissioner sign the jurat. If you do not understand the language of the document, the jurat must show that it was interpreted by a sworn interpreter, so tell us in advance if you need one. Our team can explain documents in English, French, Farsi, Russian and Serbian.

The jurat

What goes at the end of an affidavit

The jurat is the block at the end of the affidavit or declaration that records the swearing. For an in-person affidavit it states the city or town, the county or regional municipality, the date, and "Sworn (or affirmed) before me", followed by the commissioner's signature and stamp or printed name and title. For a declaration it reads "Declared before me". Exhibits referred to in the affidavit are marked by the commissioner, and any handwritten change must be initialled by the commissioner, or the affidavit may not be usable without a judge's permission.

A commissioner who signs a jurat without being satisfied the signature is genuine, or without administering the oath as the law requires, commits a provincial offence with a fine of up to $2,000. Signing a document as sworn when it was not is also an offence under section 138 of the Criminal Code.

Fees

What does a commissioner of oaths cost in Toronto?

Typical commissioning fees in Toronto
ServiceTypical feeRange published
Affidavit or statutory declaration, drafted and commissioned$120$100 to $125
Drafting an affidavit only (commissioning extra)from $53$41 to $95
Notarizing one signature or document$30$17 to $120
Each additional signature or document, same visit$22$15 to $80
Mobile visit surcharge (on top of the notary fee)$60$55 to $150

How we measured this: we reviewed the fees that 15 notary offices and law firms in Toronto and the GTA publish on their own websites, checked in November 2026. Figures are before HST unless stated. These are typical market fees, not Civitas Law's fees. Civitas Law tells you its fee in writing before any work starts, and any government fee is paid on top of the notary fee.

How Civitas Law can help

Affidavits and statutory declarations can also be commissioned by live video where Ontario's remote commissioning rules allow it, so you do not always need to come to the office. Mobile appointments at a home, hospital or office in Toronto can be arranged for an additional fee, which we confirm in writing before the visit.

By video

Remote commissioning in Ontario

The general rule in section 9 of the Commissioners for Taking Affidavits Act is that the person swearing must be in the commissioner's physical presence. Ontario Regulation 431/20, as amended, allows an oath or declaration to be taken remotely when its conditions are met. Under the province's guidance as of November 2026, those include:

  • a live connection where everyone can see, hear and communicate in real time throughout;
  • the commissioner confirming the person's identity and taking reasonable precautions, including making sure the person understands what they are signing;
  • a modified jurat stating that the oath was administered under the regulation and the location of the commissioner and of the person swearing;
  • a record of the transaction kept by the commissioner.

Nothing requires an office to accept a remotely commissioned document, so confirm with the court, tribunal or organization before choosing this route. Documents going outside Canada are a separate matter: Ontario authenticates only paper documents that were notarized, never documents that were only commissioned. See our apostille page.

Before you come

What to bring to have an affidavit commissioned

  • The document, unsigned. You sign it in front of the commissioner.
  • Valid government photo identification for each person swearing.
  • All exhibits referred to in the affidavit, in order, so each can be marked.
  • The receiving office's form or instructions, if it supplied one.
  • An interpreter, if you will swear an affidavit in a language you do not read, unless our team speaks it.

Read the whole document before the appointment. If anything is wrong, it is easier to correct it in a fresh draft than by hand at the appointment. If you are not sure what the affidavit should say, that is a legal question: book a 30-minute consultation for $150 plus HST, paid when booking, and we can review it with you.

False statements

Why the truth of an affidavit matters

Making a false statement in an affidavit or solemn declaration, knowing it is false and intending to mislead, is perjury under section 131 of the Criminal Code, with a maximum of 14 years' imprisonment under section 132. Section 134 makes a knowingly false sworn statement an offence even where the statement was not required by law. Beyond criminal law, a false affidavit can destroy your credibility in a court case or lead to an immigration application being refused for misrepresentation.

FAQs

Questions we hear often

General information, not legal advice. Every matter is different.

Who can be a commissioner of oaths in Ontario?
Lawyers and licensed paralegals are commissioners because of their licence. Ontario's regulation also lists judges, justices of the peace, members of the legislature and their constituency staff for constituent work, municipal clerks, ServiceOntario staff while serving the public, and police officers for their duties. Other people can be appointed by the province, usually with limits shown on their stamp.
Does ServiceOntario provide a commissioner of oaths?
As of November 2026, Ontario's regulation makes ServiceOntario staff commissioners while they provide services to the public. In practice each location decides which documents it commissions, often those connected to its own transactions. Call the location before you go, and remember that a commissioned document cannot be notarized or apostilled for use abroad.
Where can I find a commissioner of oaths in Toronto at no charge?
Some office holders commission documents as part of their public role, including the constituency offices of members of the provincial legislature for constituents' matters and ServiceOntario for some transactions. Whether they will commission your document, and whether they charge, is up to each office. Law offices and notaries set their own fees.
How do I get an affidavit in Ontario?
Write or obtain the affidavit form, fill in the facts you know personally, attach any exhibits, and leave it unsigned. Then book a commissioner, such as a lawyer, paralegal or notary public, and attend with photo identification. You swear or affirm that the contents are true, sign in front of the commissioner, and the commissioner signs the jurat.
Where can I go to do an affidavit in Toronto?
Any commissioner for taking affidavits can commission it: lawyers, licensed paralegals, notaries public and the office holders listed in Ontario's regulation. Our office at 4789 Yonge Street, Suite 402, near Sheppard-Yonge station, commissions affidavits and statutory declarations by appointment. Call (647) 271-1646 to book and bring the unsigned document and photo identification.
Who can make an affidavit in Canada?
Any adult who has personal knowledge of the facts and understands the oath or affirmation can make an affidavit. A corporation or partnership makes one through an officer, director, employee or partner. A person who cannot read can still swear one if it is read to them, and someone who does not understand the language swears through an interpreter.
What is required for an affidavit to be valid in Ontario?
It must state facts within the deponent's knowledge, or identify the source of information they believe, be signed by the deponent in front of a commissioner or notary, and be sworn or affirmed. The commissioner completes the jurat with the place, date and signature, marks exhibits and initials any changes.
What should you not say in an affidavit?
Do not include anything you do not know or believe to be true, opinions dressed up as facts, insults, guesses or exaggerations. Avoid argument; an affidavit is evidence, not a submission. Where something comes from another person, say who told you and that you believe it. An untrue or slanted affidavit can harm your case and expose you to perjury charges.
What documents are needed for an affidavit?
Bring the unsigned affidavit, every exhibit it refers to in the right order, and valid government photo identification. If an office gave you a form or instructions, bring those too. If you will swear in a language you do not read, arrange a sworn interpreter or ask whether our team speaks your language.
What do you write at the end of an affidavit?
The jurat. It records where the affidavit was sworn or affirmed (city or town and county or regional municipality), the date, and the words "Sworn (or affirmed) before me", followed by the commissioner's signature and stamp or printed name. A statutory declaration uses "Declared before me". Remote jurats also state the regulation and locations.
Can I swear my own affidavit?
You can be the deponent of your own affidavit, but you cannot commission it yourself. Even if you are a lawyer, paralegal or notary, a commissioner cannot take their own affidavit or declaration. Another commissioner must administer the oath and sign the jurat after you sign in front of them.
Can you commission an affidavit online in Ontario?
Yes, if the conditions of Ontario Regulation 431/20 are met: a live audio and video connection throughout, identity confirmed, a modified jurat stating the locations of the commissioner and the deponent, and a record kept. The receiving office does not have to accept a remotely commissioned document, so check with it first.
How much does it cost to get an affidavit done in Toronto?
Commissioners and notaries set their own fees, which usually depend on the number of documents, signers and exhibits, and whether the document needs drafting or review. Ask for the fee when you book. Preparing an affidavit for a court case is legal work and is priced differently from commissioning a document you bring already written.
What is a statutory declaration in Ontario?
It is a written statement of facts that the declarant solemnly declares to be true before a commissioner or notary, conscientiously believing it to be true and knowing it has the same force as an oath. It is used outside court proceedings, for example by government offices, insurers, banks and immigration authorities.
What is a sworn affidavit?
It is an affidavit that the deponent has confirmed under oath, or by solemn affirmation, in front of a commissioner or notary, who then signs the jurat. Until it is sworn or affirmed it is only an unsigned statement. Courts and tribunals in Ontario generally receive written evidence in sworn affidavit form.
Do I need a statutory declaration for a PR card or visitor visa?
Some immigration processes use statutory declarations, such as the declaration of common-law union, declarations explaining missing documents, or supporting declarations from family members. IRCC usually supplies its own form, and the form's instructions say who may witness it. Our immigration documents page explains common declarations.
What is the most common mistake when commissioning a document?
Signing the document before the appointment. The signature must be made in front of the commissioner, so a pre-signed document usually has to be printed and signed again. Other common problems are missing exhibits, handwritten changes that are not initialled, the wrong form, and a jurat missing the place or date.
What is the difference between swearing and affirming?
Swearing is an oath, usually with reference to God and often on a religious text. Affirming is a solemn promise to tell the truth with no religious content. Under Ontario's Evidence Act both are valid, they carry the same legal consequences, and the choice belongs to the person making the statement.
