Booking an Appointment: 

Contact the Township at 905-833-5321 to be connected to the next available Commissioner or e-mail us at​​. While it is not mandatory to book an appointment, it is strongly recommended so that we can ensure someone is available to assist you. We cannot guarantee availability of a commissioner without an appointment booked in advance. 

ID & Documents: The individual taking the oath and signing the document must present one original piece of government issued photo identification (Ie. a valid driver's licence or valid passport which includes a current address). Please complete the document(s) to be commissioned beforehand, but do not sign the document in advance - the Commissioner must witness your signature. 

Note: The Township does not provide Notary Public services. Our Commissioners will not sign Wills, Living Wills, Power of Attorney, Divorce, Separation or Custody Agreements. Please contact a Notary Public or lawyer who can notarize these documents.
* Affidavits regarding Wills and Real Estate require the services of a lawyer.
