If you are a single-family homeowner, a condominium property manager or street-level business, we want to learn about the source of your flooding issues.


Basement Flooding Study Area 62 is located within Toronto’s downtown and waterfront area. This area has experienced basement and recurring surface flooding during extreme storm events.

A study is underway to determine the contributing factors for surface and basement flooding and recommend solutions to improve the City’s sewer system and overland drainage routes in order to mitigate flooding problems.

Potential solutions may include:

  • Upsized sewers
  • Underground storage
  • New or upgraded pumping stations
  • Wet or dry ponds

Study Area 62 is roughly located in the area bounded by King Street East/West, Don Valley Parkway and Lake Ontario.

The City’s Low Level Combined Sewer Interceptor services the area.
