Overview

Notice: Effective January 11, 2024, Canada joined the Hague Apostille Convention.

When working, studying, or travelling abroad, end destination recipients may ask for certificates of authentication or apostilles to ensure that public documents (e.g., birth certificates, corporate powers of attorney, diplomas, etc.) are valid.

Official Documents Services ( ODS ) verifies the validity of documents by checking if the signatures and seals on the documents match their records. If the signatures and seals match, ODS will authenticate documents by issuing certificates of authentication or apostilles.

A certificate of authentication is an authentication of public documents utilized by countries that are not signatories of the Hague Apostille Convention, Abolishing the Requirement of Legalisation of Foreign Public Documents (Hague Apostille Convention).
