Starting September 2023, the City will carry out field investigations the study area to inform future design work on the recommended improvements.

In 2018, the City of Toronto completed a study to address deteriorating road conditions, traffic problems, pedestrian safety, road drainage problems and basement flooding in the Lawrence Park neighbourhood.

Following consultation with City Divisions, the public and stakeholders, the study recommended:

  • Reconstruction of number of streets, in whole or in part, with pavement widths of 7.2 metres, curb and gutter road drainage, underground storm sewers, and outfall upgrades through public and private properties
  • Installation of a perforated pipe system, where technically and operationally feasible and supported by underground conditions
  • Construction of new sidewalks on one side of five of the reconstructed streets
  • Construction of new storm sewers and sanitary sewer improvements to reduce the risk of surface and basement flooding.

In addition to the above, the study also recommended continued promotion of source control measures such as downspout disconnection and the City’s Basement Flooding Protection Subsidy Program.

The City is moving forward with preparing detailed designs for the recommended improvements in 2023 and will provide updates on opportunities to get involved.


May 2019

The Minister of Environment, Conservation & Parks approved the Lawrence Park Neighbourhood Investigation of Basement Flooding and Road Improvements Class Environmental Assessment to proceed to implementation. View letter issued to the City and decision table.

February 2018

The study report was completed and made available for a 30-day public review period starting February 12, 2018 and ending on March 13, 2018.

May 2017

City Council, at its meeting on May 24th, 2017, approved recommendations on the Lawrence Park Neighbourhood Investigation of Basement Flooding (Area 20) and Road Improvement Class Environmental Assessment Study.

A series of public consultation events were held to allow community residents to speak with staff and provide their input at key stages in the study.

As with many established neighbourhoods in Toronto, the infrastructure – roads, storm and sanitary sewers – in the Lawrence Park neighbourhood is aging. Traffic and pedestrian safety issues exist and older road drainage systems are unable to convey stormwater effectively. Historically, parts of the Lawrence Park neighbourhood have also experienced issues with basement flooding.

This Study Area is one of the 34 areas in Toronto included in the Basement Flooding Work Plan, approved by City Council to address basement flooding across the City.

The study was carried out following the requirements for Master Plans under the Municipal Class Environmental Assessment process.  A copy of the study report was made available for public review in 2018.

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.
