IMSS Application and Renewal – Authentication and Legalization (Apostille) of Canadian Birth Certificates and Marriage Certificates

Published on Friday, February 15, 2013

It is IMSS application and renewal time again!

As more and more Canadians living in Mexico are finding out, IMSS now requires  that Canadian birth and marriage certificates be “apostilled” or “authenticated and legalized” as part of the application / renewal process. If you have never heard of this process, you can learn more about it here.

If you need to have birth certificates, marriage certificates, or other Canadian documents authenticated and legalized, you have two choices:

1.   You can manage the process yourself.  This involves first having the document authenticated by the Department of Foreign Affairs in Ottawa, or by an appropriate provincial agency. The second step involves submitting the document to the Mexican embassy or one of their consulates that does document legalization.

Please note that currently, Foreign Affairs states that the processing time is 15 business days for documents that are submitted by mail or courier. It is important to make sure you have met all the requirements set by Foreign Affairs and by Mexico before submitting your documents. If your documents are not prepared correctly, they will be rejected.


2.   You can have a specialist firm, such as IDC, manage the process on your behalf.

We work with you to make sure your documents are prepared correctly.  You send your documents to our Ottawa office and we manage all aspects of the authentication and legalization process for you. We will return your processed documents to you, often in as little as one day, as opposed to five weeks or more.
