Rain Gardens

The purpose of this program is to reduce the impacts on watercourses from urban stormwater runoff by promoting on-site, lot level controls for stormwater retention and infiltration.


Landowners within the Lake Simcoe watershed may qualify for grants of 60 per cent of project costs for eligible projects, to a maximum of $5,000. Additional funds may be available from other environmental grant funding sources. LSRCA Stewardship Technicians will ensure that you are made aware of all the grant funding programs available to you.


What projects are eligible?

  • Eligible properties must be within a priority stormwater catchment area as identified by LSRCA. All projects will be considered on a case-by-case basis;
  • Projects must demonstrate a connection between roof runoff and the receiving stormwater system;
  • Rain Gardens must be located a minimum of 3 meters away from the foundation of the building;
  • Rain Gardens must not negatively impact existing trees, local drainage or neighbouring properties;
  • Projects must be designed with a minimum storage capacity for a 25 mm rainfall;
  • Project design will incorporate an appropriate outlet and/or overflow spillway, in general accordance with the 2010 CVC / TRCA Low Impact Development Stormwater Management Planning and Design Guide (Section 4.5.2: Conveyance and Overflow, Pages 4-82 to 4-83).

Project Details

  • Rain gardens are an engineered landscape feature that increases your property's ability to collect and temporarily store stormwater from rain events and melting snow.
  • Rain Gardens contain a mix of drought and water tolerant native plants.
  • These features collect water from your eaves troughs, lawn and driveway, depending on design and placement, to allow it to slowly absorb into the ground.

What costs may be covered?

  • Licensed contractor fees associated with the approved project.
  • Materials and labour associated with the approved project.
  • Design & Permits.
  • Native plants.

What isn't covered?

  • Taxes;
  • Machinery or equipment owned and used by the applicant, family dependents or the applicant's business
  • Labour of applicant, family dependents or the applicant's business;
  • Aesthetic structures/features that do not contribute to the function of the rain garden;
  • Non-native plants;
  • If you have an outstanding violation with the LSRCA, you may not be eligible for funding;
  • Work that proceeds prior to funding approval does not qualify for funding assistance.


  • An initial site visit with LSRCA staff is required. Periodic inspections may occur during the first 2 years.
  • A post construction inspection, performed by LSRCA staff, is required to confirm the rain garden design was implemented as per the submitted application.
  • Once completed, the ongoing maintenance and associated costs of the project are the responsibility of the landowner.
  • Landowner is responsible for obtaining all necessary permits (i.e., municipal, LSRCA, etc.).
  • Landowner is responsible for locates for existing underground utilities prior to construction.
  • The amount eligible for funding assistance is based upon the lowest cost estimate, or the grant limit, whichever is less.
  • Funding conditions are subject to change without notice.
