This study will follow the approved planning process for a Group 'B' project under the
Class Environmental Assessment for Provincial Transportation Facilities (2000).
This study will determine the long-term strategy to address the rehabilitation needs of
the section of Highway 401 between Warden Avenue and Brock Road. This project will
also include contract sequencing for the recommended highway improvements, safety
and operational improvements, and consideration of transit friendly initiatives.
Alternatives will be generated and evaluated based on technical and environmental
factors and in consultation with the public, stakeholders, municipalities and government
agencies.
At the completion of the study a Transportation Environmental Study Report (TESR) will be prepared, which will be made available for public review and will document:
The TESR will be made available for a 30-day public 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 purpose of the Ontario Environmental Assessment (EA) Act is to help protect and
conserve Ontario's environment by ensuring that projects subject to the Act follow a
planning process leading to environmentally sound decision-making.
For projects subject to the EA Act, an environmental assessment involves identifying and
planning for environmental issues and effects prior to implementing a project. The
process allows reasonable opportunities for public involvement in the decision-making
process of the project. An EA document is prepared by the proponent of the project
and is subject to review by the public and government agencies before project approval
is provided.
The Class Environmental Assessment (EA) for Provincial Transportation Facilities (2000) is a planning document approved under the EA Act 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 EA
Act are also fulfilled and formal approval under the EA Act 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 Canadian Environmental Assessment Act (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:
