Penalties & Enforcement

The City of Toronto enforces municipal bylaws and site controls in Etobicoke; details on fines and specific monetary penalties are not specified on the cited municipal page. [1]

  • Monetary fines: not specified on the cited page; see municipal enforcement contact for case details.[1]
  • Escalation: first, repeat and continuing offences are handled through progressive enforcement but specific amounts and ranges are not specified on the cited page.[1]
  • Non-monetary orders: site remediation orders, stop-work orders and directives to retain qualified professionals may be issued by municipal or provincial authorities; details vary by case and authority.[2]
  • Enforcers: City of Toronto Municipal Licensing & Standards and Toronto Building for municipal issues; Ontario Ministry of the Environment, Conservation and Parks (MECP) for Record of Site Condition compliance.[1]
  • Inspections and complaints: report suspected contamination or bylaw breaches via the City of Toronto complaint pages or MECP contacts listed in resources below.[1]
If a fine amount is needed for a specific case, request the enforcement file number from the city contact and ask for the exact charges.

Appeals, Review and Defences

  • Appeals: formal appeal or review routes (tribunal or internal review) are not specified on the cited municipal page; check the enforcement notice for appeal instructions or timelines.[1]
  • Time limits: specific statutory time limits for appeals or compliance are not specified on the cited page and depend on the enforcing instrument.[1]
  • Defences and discretion: defences such as reasonable excuse, reliance on a permit, or remediation plans may be considered; consult the enforcement notice and provincial rules for eligibility.[2]

Applications & Forms

The main provincial instrument for documenting site condition is the Record of Site Condition (RSC) under Ontario Regulation 153/04 (Environmental Protection Act); an RSC is prepared and filed by a Qualified Person as defined in the regulation. [2]

  • Record of Site Condition (RSC): required for many land development activities and filing is done through the Ontario Environmental Site Registry; see the registry for filing procedures.[3]
  • Environmental Site Assessment (Phase I / Phase II): prepared by a Qualified Person (QP) to support a risk assessment and RSC; the Regulation defines QP responsibilities.[2]
  • Fees: specific municipal or provincial filing fees are not specified on the cited pages; check the registry and municipal application pages for current fees.[3]
Have a Qualified Person review site history before sampling to avoid repeated fieldwork.

How risk assessments fit with municipal approvals

For development, demolition or building permits in Etobicoke you typically must submit environmental reports (Phase I/II ESA, risk assessment, RSC) as part of permit or planning applications; consult Toronto Building and Planning application checklists for submission formatting and timing. [1]

  • Timing: allow weeks to months for field testing, laboratory results and QP reporting depending on site complexity.[2]
  • Remediation plans: if contamination exceeds standards, a site-specific remediation or management plan may be required prior to permit issuance.[2]
  • Contact: consult Toronto Building or Municipal Licensing & Standards for municipal clearance requirements and contacts listed in resources below.[1]

FAQ

Do I need a risk assessment for every redevelopment in Etobicoke?
A risk assessment is often required when contamination is suspected or when an RSC is needed for redevelopment; confirm requirements with Toronto Building and the MECP based on site history and proposed use.[1]
Who can prepare a risk assessment?
A Qualified Person as defined in Ontario Regulation 153/04 must prepare and sign technical reports and RSCs used for filing on the Environmental Site Registry.[2]
How long does the process take?
Typical timelines vary from several weeks for simple assessments to months for complex sites with remediation; laboratory turnaround, field work and review affect timing.

How-To

  1. Hire a Qualified Person (QP) experienced in Ontario site assessment.
  2. Order a Phase I ESA to establish site history and risk indicators.
  3. If required, complete a Phase II ESA with soil and groundwater testing.
  4. If contaminants exceed standards, the QP prepares a risk assessment and remediation/management plan.
  5. File the Record of Site Condition on the Ontario Environmental Site Registry when ready.[3]
  6. Submit environmental reports to Toronto Building or Planning with permit or planning applications to obtain municipal clearances.[1]

Key Takeaways
