The Town of LaSalle offers Commissioner of Oaths services for documents such as affidavits and statutory declarations.  

What is a Commissioner of Oath?

A Commissioner of Oath is a person who is authorized by the Province of Ontario to take an oath when you sign an affidavit or statutory declaration. They are given this authority by the Commissioners for Taking Affidavits Act. The Commissioner is not responsible for the content of the affidavit, as it is the applicant who is swearing that the information is correct. 

Please note that Town of LaSalle staff are not Notaries Public and cannot provide notarization. If your document specifically requires notarization rather than commissioning, you will need to find a Notary Public who can provide this service.

Examples of documents we may be able to commission: 

  • Legal Name Change Application
  • Vehicle Ownership Transfers
  • Vehicle Transfers
  • Proof of Life or Pension Documents
  • Consent Letters for Children Travelling Out of the Country

Examples of documents that we cannot commission:

  • Wills (including Living Wills, Codicils to Wills and Statements of Assets of a Deceased Person)
  • Power of Attorney
  • Divorce, Seperation or Cohabitation Documents
  • Custody Documents
  • Insurance Documents
  • Financial Documents
  • Real Estate Documents
  • Other Personal-Related Documents

Right to refuse service

  • We have the right to refuse to commission documents where there is a possibility that we may be required to testify in a court of law.
  • We reserve the right to refuse to commission documents for persons who are not capable of understanding them.

Book an Appointment

We offer commissioning services by appointment. 

Book a Commissioning Appointment


Please bring the following items with you to your appointment:

  • The document requiring a Commissioner of Oaths signature (the document should be complete but should not be signed until before the Commissioner).
  • You must present one original piece of government-issued photo identification (for example, a valid driver's licence).  A Health Card is not considered a valid form of government-issued photo identification.  
  • If commissioning your document requires verification of your address, please bring proof of address. 
  • The applicant is solely responsible for obtaining and preparing all forms requiring the signature of a Commissioner of Oaths.
 Before having your document commissioned
  • The document must be in English. 
  • Read the document completely in advance. This is extremely important as you will be swearing that the statements in the document are true. When signing under oath, you are swearing as if you are testifying in a court of law that the document contains true statements.
  • You must present one original piece of government-issued photo identification (for example, a valid driver’s licence). A Health Card is not considered a valid form of government-issued photo identification. 
  • If a witness is required, bring someone who knows you. The witness must not be your spouse, child or relative. They may need to swear an Affidavit of Witness that you are who you claim to be and that they saw you sign the document.

Guarantor services

  • Commissioners do not provide guarantor services for Canadian passport applications and certification of true copies.
  • An individual cannot act as a guarantor and cannot sign an application unless they have known the applicant for a period of at least two years.
