The City of Toronto’s Basement Flooding Protection Program (BFPP) is a multi-year program that is helping to reduce the risk of future flooding by making improvements to the City’s sewer system and overland drainage routes. Learn about the scope of the study.

As part of this program, 10 Class Environmental Assessment (EA) studies are underway in areas across the City. Check out the interactive map to find out about your area. Learn about the completed environmental assessment studies.

The Basement Flooding Class Environmental Assessment (EA) Study covers any improvements to the sewer and drainage system to be made within the City’s property, such as parks, roads and sewer infrastructure.

Each homeowner is responsible for the operation and maintenance of drainage systems on private property, including:

  • lot grading
  • front and rear yard or driveway drainage and catchbasins
  • foundation drains
  • sump pumps and backwater valves
  • private tree roots and what you put down the drains (e.g. fats, oil, grease, etc.)
  • disconnecting downspouts (roof leader)

What is a Class Environmental Assessment?

Ontario’s Environmental Assessment (EA) program promotes good environmental planning by determining and managing the potential effects of a project prior to implementation.

The EA program ensures that public concerns are heard. EA balances economic, social, cultural and natural environmental needs so that projects benefit Ontario.

This study is being carried out according to the Municipal Class Environmental Assessment process. This is an approved approach to satisfying requirements of the Environmental Assessment Act specifically tailored to municipal infrastructure. The process includes identifying the problem or opportunity to be addressed, developing and evaluating a range of alternative solutions, providing opportunities for public input and identifying a preferred solution.

If concerns regarding a project cannot be resolved in discussion with the City of Toronto, a person or party may request that the Minister of the Environment, Conservation and Parks (MECP) make an order for the project to comply with Part II of the Environment Assessment Act (referred to as a Part II Order), which addresses individual environmental assessments.

To submit a Part II Order request, refer to the MECP website for instructions.
