A Commissioner of taking affidavits (also known as Commissioner of Oaths) takes affidavits or declarations by asking you to swear or affirm that what is in the document is true.
The Clerks Department provides commissioning services.

- The person signing the affidavit must be present and show government-issued identification with a current photo, such as a valid driver's license.
- Do not sign the documents in advance. You must sign in front of the commissioner, who will stamp the document once the oath has been taken and the signatures sworn.
Commissioner Services: What we can and cannot do
We do not offer Notary Public services, so we cannot certify true copies of documents or IDs. However, a Commissioner for Taking Affidavits at the Clerk's Office can help with most sworn statements and declarations.
A Commissioner is authorized by the Ministry of the Attorney General for Ontario to administer oaths and take affidavits. This is different from a Notary Public, who has broader powers. For documents that need a Notary’s signature or certified copies, contact a lawyer or a Notary.
