Proposal details

A risk assessment was undertaken for this property to establish the risks that the contaminants identified in the risk assessment may pose to future users and to identify appropriate risk management measures to be implemented to ensure that the property is suitable for the intended use of “industrial” and “commercial” use as defined by Ontario Regulation 153/04.

The ministry’s review of the risk assessment involved the following reports, documents and information /correspondence:

  • pre-submission Form for 73 and 95 Curtis Drive, Guelph, Ontario. Prepared by GHD Limited, dated June 21, 2022;
  • risk assessment for 73 and 95 Curtis Drive, Guelph, Ontario. Prepared by GHD Limited, dated September 21, 2023;
  • risk assessment for 73 and 95 Curtis Drive, Guelph, Ontario. Prepared by GHD Limited, dated May 17, 2024; and,
  • risk assessment for 73 and 95 Curtis Drive, Guelph, Ontario. Prepared by GHD Limited, March 6, 2025

Based on the documents provided to the ministry as part of the risk assessment report, the reviewers can confirm that the risk assessment has been conducted in accordance with the Environmental Protection Act (the act), Ontario Regulation 153/04 (the regulation), and the associated guidance documents.

The director provided the proponent with written Notice of the Director’s Decision to accept the risk assessment No. 5866-CFSRVW relating to the property in accordance with section 168.5 of the act on May 22, 2025.

The director is considering the issuance of a Certificate of Property Use (CPU) in relation to the site.
