RN Developments Inc. - Certificate of property use

A risk assessment was undertaken for this property to determine the risks that the contaminants identified in the risk assessment may pose to future users and to establish appropriate risk management measures to ensure that the property is suitable for the proposed residential use, as defined in Ontario Regulation 153/04 (the "Regulation") as amended, and made under the Environmental Protection Act.

Based on the documentation presented to the ministry in the form of a risk assessment report, ameliorated over several iterations, the reviewers confirmed that the risk assessment has been conducted in accordance with the Act, the Regulation, and the associated guidance documents.

On December 23rd, 2025, the director issued to the proponenta written Notice of the Director's Decision to accept the risk assessment relating to the property in accordance with section 168.5 of the act.

The director is considering issuing a Certificate of Property Use (CPU) in relation to the property. The CPU incorporates the risk management measures proposed in the risk assessment and additional measures specified by the director. A section 197 Order is included and requires that a certificate be registered on the property title in accordance with section 197 of the act such that before dealing with the property in any way, a copy of the CPU must be given to any person who will acquire and interest in the property,

The proposed risk management measures include:

• barriers to property soils, such as a fill cap and hard cap
• a barrier inspection and maintenance program
• an active soil vapour intrusion mitigation system to extract contaminant vapours from under the proposed new building slab, convey them in a vent riser and evacuate them to the atmosphere
• a health and safety plan
• a soil and groundwater management plan
• prohibition on growing plants outdoors
• an absence of groundwater use

The draft CPU number 1386-DP7SBD, which includes the section 197 Order, can be accessed from the Supporting Materials section of this notice.
