These flood control improvements are funded through a dedicated Stormwater Fee charged to all property owners; residential and non-residential. The annual fee of $51 per residential property and/or $28.50 per $100,000 (2021 rate) of Current Value Assessment (CVA). The residential property will increase $1 per year, and the non-residential fee will increase by 2% each year thereafter.

This fee is applied to the Final Tax bill for each property owner in Markham.

Who Will Pay the New Fee?

To help fund the program, a Stormwater Fee is charged to all properties in the City of Markham. This fee, combined with revenue from the Canada Gas Tax and other grants, will provide dedicated funds for both approved and future Stormwater infrastructure improvement projects City-wide.

Pursuant to the City of Markham’s By-law 2019-100 “The Non-Residential Stormwater Fee rate of $28.50 per $100K of CVA is to be adjusted to compensate for the average change in CVA.” The resulting annual adjustments to the non-residential Stormwater Fee rate are summarized in the table below:

Non-Residential Rate per $100,000 in CVA
2021 $28.50
Subsequent Years %2 increase, adjusted for average change in CVA

The adjusted non-residential Stormwater Fee rate is not retroactive – it is applicable to the year in which it was adjusted.
