Ownership Changes

Law Offices

Please send all ownership change notifications via email (in PDF format) to

Property Owners

If you receive a tax bill for a property you no longer own, we ask that you forward the tax bill to the new owner or return it to the tax office, indicating that a transfer of title has been made.

If you have purchased a property and have not received an ownership change letter from the tax department within one month of the closing date, please contact our office.

If you are moving and pay your taxes online, by telephone, or at a bank, please be aware that your property roll number is not transferable. To ensure that your payments are applied to the correct account, be sure to change the roll number (account number) in your banking to the roll number for the new property.

Pre-Authorized Payment Plan Participants

If you are moving to a new property in Sarnia and currently pay your taxes through our pre-authorized payment plan, please be aware that the program is not transferable.

You must cancel your old payment plan and complete a new Application Form for your new property. Please advise the City by the 20th of the month in which the change is required.

Ownership Change Administration Fee

An Ownership Change Notice is issued when the City is advised that a property has sold. This notice includes the current account balance and the tax due dates. A fee, as per Council Approved Fees for Service is applied to process ownership changes. This fee will be added to the property tax account and will be included in the Ownership Change Notice that is mailed to the new owner.

Title Searches, Ownership/Deeds, and Land Registry

The City does not hold or provide property records regarding title, deed, or records of sale. Provincial Land Registry Offices offer self-service options including searches for land ownership documents such as deeds, mortgages, and plans of survey for title and are accessible online through the Provincial website. Click here for more information or retain independent legal advice:
