Effective January 9, 2026, a new interactive application is available and must be submitted when:

  • applying for a new commissioner or notary public appointment

Overview

A commissioner for taking affidavits can take affidavits and administer oaths, affirmations or declarations. Commissioners are governed by the Commissioners for Taking Affidavits Act.

People holding specific offices (for example, lawyers, paralegals and municipal clerks) are automatically commissioners and don’t need to apply.

Find a complete list of these office holders 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. Notaries are governed by the Notaries Act.

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.
