If you’re a property owner in Mississauga, a stormwater charge began appearing on your Region of Peel water bill in 2016. The Region bills for the charge on behalf of the City. The money collected from this charge is used exclusively to meet the increasing demand and investment for stormwater management, including planning and operations, new capital construction and improvements.

Your annual stormwater charge is divided into a daily rate. Each bill will show the stormwater charge for the number of days that have passed since your last bill, so it may vary from bill to bill.

How the charge is calculated

Charges are calculated the same way for all types of properties. A stormwater assessment is updated each year for every property in the City based on the most recent aerial imagery.

Billing units and the annual rate

A billing unit represents the average hard surface area on a single detached residential property. To calculate the charge, the number of billing units is multiplied by the annual rate per unit.

The annual rate gets approved by Council and is reviewed every year as part of the City’s annual business plan and budget process.
