Overview

In Ontario, commissioners and notaries help protect people from fraud by helping to verify the integrity of documents used in commercial and legal transactions.

A commissioner for taking affidavits can take affidavits and administer oaths, affirmations or declarations.

Certain professions (for example, lawyers, paralegals and municipal clerks) are automatically commissioners and don’t need to apply. You can find a complete list of these professions here.

A notary public has all the powers of a commissioner for taking affidavits, and can also verify that signatures, marks and copies of documents are true or genuine.

If you are a lawyer or paralegal, there is a separate process to apply. Learn how to become a notary public if you are an Ontario lawyer or paralegal.
