Environmental Impact Studies (EIS) Guideline and Checklist


An Environmental Impact Study (EIS) is used to provide a sufficient level of detail to demonstrate that a proposed development will have no negative impacts on the natural features or ecological functions of the subject and surrounding (“adjacent”) lands. An EIS does not ensure that development proposals will be approved.  Their purpose is to inform the design and configuration of the development, to avoid negative impacts at the outset, and to identify appropriate mitigation and/or compensation for unavoidable impacts. 

When do you need an EIS?

The need to complete an Environmental Impact Study (EIS) will be identified during the consultation stage for Site Plan or Plan of Subdivision applications.  Recommendations from the EIS are used to develop conditions of Draft Plan Approval (Subdivision) or Site Plan Approval. These recommendations may include additional study requirements, restoration and monitoring.

More Information

The downloadable Environmental Impact Study Guideline Document (p.1-5) and Checklist (p. 6-7) provide more detail regarding your requirements with regard to undertaking an EIS, where necessary.

Important to Remember

When development is undertaken, there are inevitably ecological impacts: Identifying these impacts does not necessarily result in rejection of the proposal, provided that the natural heritage features and ecological functions identified in the Provincial Policy Statement and City of London Official Plan are protected from potential threats. 

For this reason, it is imperative that the EIS clearly specifies what the impacts on natural heritage features and/or ecological functions the proposed development will have. It will address how the proposal will avoid negative impacts and/or, if impacts cannot be fully avoided AND how the proposal will mitigate or compensate for residual impacts on ecologically sensitive features and functions.
