Environmental Protection Ontario 3 Minutes Read · published May 24, 2026 Flag of Ontario · By Daniel Roy

Richmond Hill, Ontario project owners must often prepare mitigation plans as part of development approvals and construction permits; these plans address environmental protection, erosion control, tree and habitat management, and site restoration. Check the city's development application pages for submission requirements and technical guidelines, and for pre-application advice contact Planning or Development Engineering Development Applications[1].

Requirements for Mitigation Plans

Mitigation plans are typically required where a proposal could affect natural features, stormwater, or neighbouring properties. Typical components include an environmental impact assessment, erosion and sediment control plan, tree protection plan, staging and access plan, and a monitoring schedule. Where the city requires these documents they are evaluated against the Official Plan, Zoning By-law conditions and site-specific agreements.

  • Environmental impact assessment or report.
  • Erosion and sediment control drawings and staging notes.
  • Tree protection plan and compensation measures.
  • Monitoring and inspection schedule during and after works.
Begin engagement with city staff early to clarify scope and technical expectations.

Submission, Approvals and Security

Mitigation plans are submitted with development or building permit applications and may be required as conditions in site plan agreements or permits. The city can require securities or letters of credit to ensure completion of mitigation works; the amount and conditions are project-specific and typically set in an agreement or permit.

  • Submit plans with the development application package and any required technical reports.
  • Securities or cash deposits may be held until works are completed and accepted.
  • Consult Development Engineering and Planning for clearance and release of securities.

Penalties & Enforcement

The City enforces compliance through its By-law Enforcement and Development Engineering teams; specific enforcement tools include orders to stop work, orders to remediate, administrative monetary penalties, permit suspensions, and prosecution in court. Where exact fine amounts or daily penalties are required by bylaw text those figures are not specified on the cited pages below and must be confirmed in the applicable bylaw or agreement.[2]

  • Fine amounts: not specified on the cited page.
  • Escalation: first, repeat and continuing offences - not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, remedial orders, permits withheld or revoked, seizure of materials.

  • Appeal/review: specific appeal routes and statutory time limits are set out in the relevant bylaw or agreement and are not specified on the cited page.
If work is underway without approved mitigation measures, the city can require immediate remediation or stop work orders.
