Authentication of Documents in Ontario for Use Abroad: Complete Guide
If you are planning to work, study, do business, or handle personal matters abroad, you will very likely need to authenticate official documents issued in the province of Ontario. Since January 11, 2024, Canada has been a member of the Hague Apostille Convention, which has significantly simplified the authentication process for international use.
What is document authentication?
Authentication is a process by which the provincial government verifies that the signatures and seals on your public documents (such as birth certificates, diplomas, notarial powers of attorney, or court documents) are genuine. Once verified, a certificate of authentication or an apostille is issued, which allows those documents to be legally recognized in other countries.
Apostille vs. Certificate of Authentication: Which Do You Need?
- Apostille: Used for documents that will be presented in countries that are signatories to the Hague Apostille Convention. With an apostille, additional legalization at consulates or embassies is generally not required.
- Certificate of authentication: Required for countries that are not signatories to the Convention.
Important: Before starting the process, we recommend contacting the consulate, embassy, or final recipient in the country where you will use the document to confirm which type of authentication they require.
Important changes starting in 2024
The addition of Canada to the Hague Apostille Convention has brought two main changes:
1. Simpler process: Many documents no longer require the additional steps of consular legalization.
2. Greater international acceptance: The apostille is recognized in more than 120 signatory countries.

Final recommendations
- Plan ahead: The process can take several days or weeks, especially if you need certified translations.
- Confirm the requirements of the destination country: Not all countries accept the apostille; some still require additional consular legalization.
- Consult a professional: If you have questions, consider seeking advice from a notary public or specialized authentication services, especially if your documents are in Spanish.

Steps to authenticate a document in Ontario
1. Check whether your document is eligible
The Official Documents Services (ODS) is the authority responsible for issuing certificates of authentication and apostilles in Ontario. You can check the online authentication portal to verify whether your document is eligible before continuing.
- Document authentication portal: https://www.officialdocuments.mgcs.gov.on.ca
2. Documents in other languages (translation requirement)
If your document is written in a language other than English or French, you must include a translation. There are two valid options:
- Option 1: Translation by a Canadian certified translator (member of a recognized provincial translators association).
- Option 2: Attestation of the translation by an Ontario notary public who speaks English or French and the document's original language, and who certifies the accuracy of the translation.
📌 Important note: The ODS will not authenticate documents that are only in Spanish without an official translation into English or French.
3. Documents that no longer require prior notarization
Thanks to Canada's accession to the Hague Convention, certain new documents can be authenticated directly, without prior notarization:
- Diplomas, degrees, and academic transcripts from public postsecondary institutions in Ontario issued from January 2019 onward.
- Court documents issued by the Superior Court of Justice or the Court of Justice of Ontario from July 10, 2023 onward.
4. Submit your application
You can start your authentication application online through the official portal. After submitting it, you will receive a confirmation number by email. You must then mail or deliver in person your documents, the application number, and the corresponding payment to the ODS office.
