What is a Terms of Reference and an Environmental Assessment (EA)?

Terms of Reference

The first step in an application for approval to proceed with the planning of a project or undertaking under the Environmental Assessment Act (EAA) is the submission of a proposed Terms of Reference (ToR) for the Environmental Assessment (EA). Public and agency consultation is required on the preparation and submission of the ToR to the Ministry. Approval is required by the Minister of the Environment. If approved, the ToR provides a framework or work plan for what is going to be studied in the EA. When an application is made to the Ministry, the proponent is required to submit a ToR summary form to the Ministry in accordance with O. Reg 615/98.

An Environmental Assessment (EA) is a study which assesses the potential environmental effects and benefits of a project or undertaking on the environment. Key components of an EA include: consultation during the preparation and submission of the EA to the Ministry with those government agencies, members of the public, municipalities, other stakeholders or aboriginal communities which may be affected; the consideration of alternatives; and the mitigation and management of environmental effects. A proposed EA must be consistent with the approved ToR. Approval is required by the Minister and Cabinet prior to proceeding with a project. Submission of an EA must be accompanied by a summary, lists of studies and reports and maps as required by Section 2(1) of O. Reg 334.
