Excess Soil Regulation

March 13, 2023

In December 2019, the Ministry of Environment, Conservation and Parks finalized O. Reg. 406/19: On-Site and Excess Soil Management (Excess Soil Regulation), supported by the Rules for Soil Management and Excess Soil Quality Standards document (Soil Rules), to support local reuse of excess soil. This regulation is being phased in, and the first part came into effect on January 1, 2021.

As of January 1, 2023, the second phase of the Excess Soil Regulation came into effect, which includes:

  • Excess soil reuse planning requirements for certain projects
  • Registration and procedures for large reuse sites
  • Physical or electronic hauling records
  • Registration for residential development soil depots

To help ensure the regulation and Soil Rules document are effective and practical, amendments were also made to the Excess Soil Regulation, which came into effect on January 1, 2023. To find out more about the amendments, please see the Environmental Registry of Ontario.

Excess Soil Webinars

MECP will be hosting webinars to provide information on the key requirements under the regulation, on the following topics:

  1. Low Risk Projects: this webinar is focused on projects that do not have to complete the excess soil reuse planning requirements, but may still be required to follow other requirements for soil management under the regulation.
  2. Project Area Requirements: this webinar is for general requirements for a project excavating soil, including the reuse planning requirements for larger and riskier projects


If you are interested in one of these topics, please register through the Eventbrite links provided below:
