How to Authenticate Your Documents in Ontario (Step-by-Step Guide)
Authenticate documents in Ontario for international use. Learn about document authentication, official documents, and authentication services.
If you need to use an Ontario document outside Canada, you usually have to have it authenticated to ensure the signature, seal, or stamp is genuine. Authentication allows foreign governments to ensure that the document is authentic for purposes such as immigration, employment, education, marriage, business deals, or court cases. Official Documents Services handles this in Ontario for documents that were issued or notarized in the province. On January 11, 2024, Canada joined the Hague Apostille Convention. Now, many documents intended for member countries are issued with an apostille rather than going through the old multi-step legalization process.
Some countries accept an apostille, while others that are not party to the Apostille Convention may still require additional legalization after authentication. This guide provides a clear, step-by-step explanation of how to authenticate or apostille documents in Ontario, including eligibility requirements, notarization rules, submission procedures, fees, and common mistakes to avoid.

What Does Authentication and Apostille Mean?
Definition of Document Authentication
Document authentication is the official process of confirming that a signature, seal, or stamp on an Ontario document is genuine. It verifies that the signature belongs to a recognized official or notary whose signature is on record with the authentication authority. Authentication does not confirm that the information in the document is true. Instead, it confirms the authenticity of the signature or seal, enabling the international document to be accepted for official use in another country.
Authentication is commonly required for documents for use outside of Canada, including:

- Birth, marriage, or death certificates
- Court-issued documents
- Diplomas and academic records
- Notarized affidavits or powers of attorney
What Is an Apostille and How Is It Different?
An apostille is a certificate issued for documents that will be used in countries that are members of the Hague Apostille Convention. Canada joined the Convention on January 11, 2024. For these member countries, an apostille replaces the older multi-step legalization process.
In Ontario, eligible documents are issued an apostille certificate by the provincial authority after the signature or seal on the document has been verified.
The key difference is:
In Ontario, eligible documents are issued an apostille certificate by the provincial authority after the signature or seal on the document has been verified.
The key difference is:
- Apostille – Used for Hague Convention countries; embassy legalization is generally not required.
- Traditional authentication and legalization – Used for non-member countries; the document may require additional certification by the destination country’s embassy or consulate.
Hague Apostille Convention vs. Traditional Document Authentication and Legalization
What Changed After January 11, 2024
On January 11, 2024, Canada joined the Hague Apostille Convention. As a result, Ontario can now issue an apostille for documents that will be used in other member countries of the Hague Apostille Convention. An apostille replaces the older multi-step process that required authentication followed by legalization at a foreign embassy or consulate.
For many people submitting a Canadian document abroad, this change significantly simplified the process. For member countries, the apostille acts as the final certification showing that the signature or seal on the document is authentic.

When Additional Legalization Is Still Required
If the destination country is not a signatory to the Hague Apostille Convention, the traditional process still applies. This typically involves:
- Authentication by the appropriate Canadian competent authority, which may include Global Affairs Canada for federal documents
- Legalization by the embassy or consulate of the destination country
Why You Might Need Authentication or an Apostille Certificate
Common Reasons People Authenticate Documents
You may need authentication or an apostille when presenting an Ontario-issued or notarized legal document to a foreign government or institution. Many countries require official proof that a signature or seal is genuine before foreign officials will accept it. This requirement usually applies to:
- Immigration and visa applications
- Foreign work permits or employment contracts
- Admission to schools or universities abroad
- Marriage registration in another country
- International business transactions
- Court proceedings outside of Canada
Why Destination Country Requirements Matter
The correct process depends entirely on the country where the document will be used. If the country has signed the Hague Apostille Convention, an apostille issued in Ontario is generally sufficient. If the country is not a member of the Hague Convention, the document typically requires authentication followed by legalization through that country’s embassy or consulate.

Step-by-Step Guide to Authenticate Documents and Complete the Apostille Process
Step 1: Confirm the Requirements of Your Destination Country
Before starting the process, confirm the requirements of the country where your document will be used.
Determine:
Determine:
- Whether the country is part of the Hague Apostille Convention
- Whether an apostille alone is sufficient or if additional legalization is required
Step 2: Prepare the Correct Document (Original or Notarized Copy)
Make sure you are submitting the correct document format before beginning the process.
- Government-issued documents must usually be original certificates or officially certified copies.
- Private documents must typically be notarized before submission.
Step 3: Get the Document Notarized (If Required)
If your document is considered a private document, it must be notarized by a licensed Ontario notary public before it can be authenticated or apostilled. The notary public verifies the identity of the signer, witnesses the signature, and applies an official signature and seal. This confirms the document’s authenticity and allows the signature to be verified during the authentication or apostille process. Without proper notarization, most private documents will not be eligible for authentication or apostille.
Step 4: Submit Your Documents to Ontario’s Official Documents Services (ODS)
You must submit your documents to the Ontario Official Documents Service, the provincial authority responsible for issuing apostilles and authentication certificates.
When you send your document, you will typically include:
When you send your document, you will typically include:
- The document requiring authentication or an apostille
- A completed application form
- The required government processing fee
- A return envelope or courier details
Step 5: Receive Your Apostille or Authentication Certificate
After processing, your document will be returned with the apostille or authentication certificate attached. If the destination country requires further legalization, you must then submit the authenticated document to that country’s embassy or consulate to complete the process.
