This study will follow the approved planning process for a Group 'B' project under the Class Environmental Assessment for Provincial Transportation Facilities (2000).
The TESR will be made available for a 30-day public and agency review period. If there are serious
concerns about the project that cannot be resolved through discussions with MTO, a request can be
submitted to the Minister of the Environment to make a Part II Order ("bump up") for the project,
thereby requiring the preparation of an Individual Environmental Assessment for the proposal
documented in the TESR. If there are no outstanding concerns after the public review period, the project
is considered to have met the requirements of the Class EA and may proceed to detail design and
construction, contingent upon the receipt of all other required approvals, permits and authorizations.
Environmental clearance of the TESR ensures that the environmental assessment requirements have been met before proceeding to detail design and construction, including ensuring the study process set out in the Class EA has been applied, and that the transportation engineering, environmental protection, evaluation, consultation, documentation, and bump-up principles have been applied throughout the project.
The Class Environmental Assessment (EA) for Provincial Transportation Facilities (2000) is a planning document approved under the OEAA that provides a streamlined process that projects or activities within a defined "class" must follow. When the Class EA process is adhered to and its requirements met for a project, the requirements of the OEAA are also fulfilled and formal approval under the OEAA is not required.
The Class EA requirements must be met before a project can be implemented. Projects and activities that are defined within a "class" are generally ones that are recurring, carried out routinely and have predictable environmental effects that can be mitigated to some extent.
The word "environment" in this context is defined as any aspect of life that may be impacted by the undertaking. Therefore, "the environment" can include aspects of the natural, social, economic and cultural environments depending on the project in question. The Class Environmental Assessment for Provincial Transportation Facilities (2000) outlines the EA process to be followed for specific groups of provincial transportation projects. Project groupings within the Class EA have been established for the purposes of consultation, documentation and formal EA challenge (bump-up).
The groups are as follows:
Other aspects of the environmental assessment process applicable to these project types are contained in the Class Environmental Assessment for Provincial Transportation Facilities (2000). Readers interested in these matters are encouraged to refer to that document.
In addition to the Ontario Environmental Assessment Act (OEAA), the Canadian Environmental Assessment Act (CEAA) requires that some projects undergo a federal EA process. The CEAA is "triggered" by the following:
The federal process is conducted either as a Screening or a Comprehensive Study. A Screening under the CEAA must include:
