Environmental Protection Ontario 4 Minutes Read · published May 24, 2026 Flag of Ontario · By Daniel Roy

Windsor, Ontario property owners, developers and members of the public may need access to contaminated site records for due diligence, redevelopment or public health reasons. This guide explains where records are held, which municipal and provincial offices are involved, how to request records, and what enforcement or penalties may apply under city bylaws and provincial site‑remediation rules. Follow the steps below to search provincial registries, contact City of Windsor departments, or submit an access request.

Where records are kept

Records about soil or groundwater contamination and remediation are commonly found in provincial filings called Records of Site Condition (RSC) and in municipal planning or building files where remediation was a condition of approval. Start with the provincial registry for RSCs and then check City of Windsor planning/building and by-law files for site-specific documents. See the provincial RSC guidance and City planning pages for how to search and request records via official channels City of Windsor Brownfield Redevelopment[1], Records of Site Condition (RSC) - Ontario[2], and the municipal by-law contact page City of Windsor By-law Services[3].

Penalties & Enforcement

Enforcement for contamination, remediation orders and related offences can involve municipal by-law officers (for local property standards or soil movement bylaws), the City of Windsor Planning and Building departments (for development conditions), and the Ontario Ministry of Environment, Conservation and Parks for provincial remediation obligations and RSC filings.

  • Fine amounts: not specified on the cited page for Windsor-specific contaminated-site fines; provincial orders and penalties are set out under provincial law and vary by offence.
  • Escalation: first, repeat and continuing offence ranges are not specified on the cited municipal pages; provincial enforcement may include orders that continue until complied with.
  • Non-monetary sanctions: remediation orders, stop-work orders, orders to remediate or restore, and seizure of equipment or materials where authorized.
  • Enforcer and complaints: City of Windsor By-law Services, Planning and Building Departments handle municipal complaints; provincial complaints and RSC oversight are through the Ministry of the Environment, Conservation and Parks.
  • Appeals/reviews: appeal routes depend on the issuing authority; time limits for appeals are not specified on the cited city pages and may be set by statute or regulation.
If a fine or specific penalty is needed for a case, request the enforcing by-law section or order number from the issuing department.

Applications & Forms

The provincial Records of Site Condition are filed through the Ontario RSC system; the RSC guidance and filing process are published on the provincial page cited above. No single Windsor municipal contaminated‑site form is published on the city pages cited; requests for municipal records may require an access to information request under MFIPPA to the City Clerk or a direct request to Planning/Building depending on the file type.[3]

How to request records

  1. Search the Ontario Records of Site Condition registry to locate any registered RSCs for the property and download available documents. [2]
  2. Contact City of Windsor Planning or Building to ask whether remediation files, site plans, or conditions of approval exist for the address; request file reference numbers and submission copies. [1]
  3. If records are not public online, submit a formal access to information request to the City Clerk under MFIPPA; follow city instructions on fees and timelines. [3]
Request clarity on whether any remediation agreements or easements affect the property title.

Action steps

  • Start with an online RSC search, then allow time for municipal staff to retrieve older paper files.
  • Prepare property identifiers: municipal address, plan/lot, roll number and owner name to speed retrieval.
  • Be ready to pay municipal MFIPPA search or reproduction fees if applicable.
  • If remediation is required, ask for enforcement file numbers and any orders affecting development timelines.
