Storm Sewer Fees - A change to your Property Taxes

The third and fourth property tax bill installments for 2019 are in the mail. When opening your bill you will notice a change with respect to Storm Sewer Fees.

In prior years, the storm sewer amount was included in the general levy (tax rate) so every homeowner paid a storm sewer rate, even if the property was not on, or planned to be on, storm sewers.

New for 2019, as per Council’s decision during the 2019 budget deliberations, properties within the "Storm Sewer Urban Boundary” will have a flat fee applied for Storm Sewers depending on the property type. The new Storm Sewer Fee is identified on your tax bill under ‘Special Charges’, as circled below.

How will this affect my bill?

The Storm Sewer Fee is an annual flat fee that has been split between your third and fourth installments. Therefore, if, for example, you own a single-family property with an annual fee of $100.00, $50.00 has been added to your third installment, due on July 2, 2019 and the remaining $50.00 has been added to your fourth installment, due October 1, 2019.

Starting in 2020, the annual Storm Sewer Fee will be divided between all four installments. Therefore, for a single-family property with an annual Storm Sewer Fee of $100.00, $25.00 will be added to each installment.

The Billing of Realty Taxes is normally done through an Interim Tax Bill provided in January and a Final Tax Bill produced in June. Both Interim and Final Bills are payable in two instalments with due dates at the 1st of each month as follows:

INTERIM DUE DATE:     March and May
FINAL DUE DATE:     July and October

Properties with more than one property class, i.e. Residential and Commercial mixed assessment. Property owners will receive one Tax Bill for both assessment classes.

Interim Tax Bills are calculated using the following formula:
Present Year Assessment X ½ of Last Years Tax Rate

Please be informed, due to current legislation, the Interim Bill cannot amount to more than ½ of the previous year's Final Adjusted Taxes. The Interim Bill does not represent half of the current year's taxes.

Owners of Residential or Farm properties can calculate their annual taxes by multiplying the property's assessment by the appropriate tax rates.

Property Tax Bills for portions assessed (in whole or in part) in the Commercial, Industrial or Multi-Residential classification are subject to Capping Legislation. Therefore final taxes are not limited to the Assessment multiplied by the tax rates otherwise referred to as CVA taxes.
