EA Process

Ontario Environment Assessment Act (OEAA)

An Environmental Assessment, or EA, is a decision-making process used to promote good environmental planning by assessing the potential effects of certain activities on the environment. In Ontario Environmental Assessments are defined and authorized under the Ontario Environmental Assessment Act (OEAA), R.S.O. 1990. To fulfill the requirements of the OEAA, MTO developed the Class Environmental Assessment for Provincial Transportation Facilities (2000) (Class EA) process.

Class EA Process

The study has followed the approved planning process for a Group “B” Detail Design project in accordance with the Class EA. The purpose of the Class EA process is to ensure that governments and public bodies consider potential environmental effects before an infrastructure project begins.

As part of the Class EA process for Group “B” projects there are opportunities for public input throughout the study (See the Consultation section for details).

This Class EA process has three major phases; Planning, Preliminary Design and Detail Design. This project will build on the work completed during the Preliminary Design and Class EA as documented in the 2013 Transportation Environmental Study Report (TESR) available in the Documents page.

The Detail Design phase of the EA process will include input from engineering and environmental specialists in the areas of road and traffic engineering, advanced traffic management systems engineering, electrical engineering, surveying, geotechnical and foundation engineering, land use, noise, landscape, contaminated property, groundwater, water quality and drainage, aquatic and terrestrial biology, wildlife and birds, cultural heritage and archaeology.

Two Public Information Centres (PIC) will be held during the study to give the public an opportunity to meet with the Project Team and provide input to the project. Two Community Workshops will also be held during the project. See the Consultation section for details on PIC and Community Workshops.

A Design and Construction Report (DCR) will be prepared at the end of the project and be available for a 30-day Public Review Period. The DCR documents the entire study process, including a detailed description of the design and details of environmental impacts and proposed methods to reduce, minimize or avoid impacts.
