What is my account number to add as a bill payment for online banking?

The roll number shown on your tax bill is the account number that you will need to use. Please remember no spaces, dashes or decimals.

What happens if my payment is late?

Penalty and interest are charged 15% per annum, applied the first business day of each month on all past due balances. Late payment charges are set in accordance with current legislation and cannot be waived. If payment in full is not received by the installment due date, a property tax arrears notice will be issued and a $5.00 fee will be applied. Failure to receive a bill does not excuse the home owner from payment responsibility.

Pie Chart showing Property Tax Breakdown

  1. Education taxes – This tax rate is set by the Province of Ontario and remitted to the local school board you support.
  2. Municipal taxes – The tax rate to cover the costs of supplying municipal services is based on city council’s adoption of our annual budget. Revenues from provincial grants, user fees and other sources are deducted from the total expenditures, resulting in a final amount that needs to be raised through taxation.
  3. County taxes – A portion of the tax bill for all residents of County of Lambton goes back to the County to support their role in supplying various services including Ontario Works, Social Housing, Library and Cultural Services and Land Ambulance.
