Flood Control Program identifier

Markham has a new Flood Control Program. It will improve storm drainage capacity and limit surface and basement flooding risks in urban areas.

Flood control improvements will be funded through the Stormwater Fee charged to all property owners; residential and non-residential. This fee, combined with revenue from the Canada Gas Tax, will help fund both current and future stormwater infrastructure improvement projects city-wide.

Residential Stormwater Fee: $51 per residential property

Non-Residential Stormwater Fee: $28.50 per $100K of Current Value Assessment (CVA)

This fee is applied to the final tax bill for each property owner in Markham, effective since Fall 2015 and Fall 2016 for non-residential business and vacant land owners.


Annual Adjustments

As per the City of Markham's By-law 2015-130, the Non-Residential Stormwater fee rate adjusts to account for the average change in CVA. The resulting annual adjustments are summarized in the table below:

Non-Residential Rate per $100,000 in CVA
2020 $0.00
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.
