Mandatory Downspout Connection

In Toronto, it’s mandatory for property owners to disconnect their downspouts from the city’s sewer system – doing so reduces the risk of basement flooding and improves our city’s water quality.

While mandatory downspout disconnection is already in effect for most of Toronto, the final area – including parts of Ward 25 – will be required to disconnect by December 3, 2016.

To see when your disconnection comes into effect, you can view this map.
