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. In order to fulfill the requirements of the OEAA, MTO developed the Class Environmental Assessment for Provincial Transportation Facilities (2000) process.

Class EA Process

approved planning process for a Group ‘B’ project in accordance with the Class Environmental Assessment for Provincial Transportation Facilities (2000) [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

The study will follow the process for Group 'B' projects there are opportunities for public input throughout the study (See the Consultation section for details).

The environmental assessment process will include input from engineering and environmental specialists in the areas of road and traffic engineering, electrical engineering, geotechnical and foundation engineering, land use, noise, landscape, contaminated property, groundwater, water quality and drainage, aquatic and terrestrial biology, wildlife and birds, and archaeology.

Two rounds of Public Information Centres (PIC) will be held during the study process to give the public an opportunity to meet with the Study Team and provide input to the study. See the Consultation section for details on PICs

A Transportation Environmental Study Report (TESR) will be prepared at the end of the study and will be made available for a 30-day Public Review Period. The TESR documents the entire study process, including a detailed description of the Recommended Plan and details of environmental impacts and proposed methods to reduce, minimize, or avoid impacts.

During the 30-day public review period of the TESR, the public will have the opportunity to submit their comments directly to the Project Team. At that time, concerns or issues that cannot be resolved through discussions with the Project Team can be submitted directly to the Minister of the Environment and Climate Change (i.e., a Part II Order Request), with a request that the study be carried out as an Individual Environmental Assessment Study.
