MTO Class Environmental Assessment (EA) Process

Contracts A and B are following the approved planning process for a ‘Group B’ in accordance with the MTO Class EA for Provincial Transportation Facilities (2000).  The two contracts are proceeding along different design and construction timelines and will therefore each follow a separate MTO Class EA Group B process.  A Public Information Centre is planned for Contract B at a future date and advance notification will be provided.

A Design and Construction Report (DCR) has been prepared to document the study process completed for Contract A including the recommended detail design improvements, anticipated environmental impacts and proposed mitigation measures as well as the consultation undertaken throughout the process.

The Contract A DCR can be accessed on the Documentation page

Contract B

A separate Design and Construction Report (DCR) will be prepared to document the study process completed for Contract B including the recommended detail design improvements, anticipated environmental impacts and proposed mitigation measures as well as the consultation undertaken throughout the process.

The DCR for Contract B will be made available at a future date and will be placed on the public record for a 30-day comment period. Notification regarding the availability of the report will be provided.
