Environmental Assessments

An Environmental Assessment is required for all large-scale projects that have potential impact on the environment. These projects require approval from the Government of Ontario before proceeding to the next phase. Certain projects that have more predictable environmental impacts or effects, and are more readily managed, can now follow an Ontario Ministry of the Environment-approved, streamlined approach. Metrolinx worked with key stakeholders and developed these regulatory and legislative changes for transit projects.

Taking the streamlined approach still protects the environment, but shortens the timeline to six months for commencement, review and approval. This Environmental Assessment process for transit projects is known as the Transit Project Assessment Process.

Check back here for transit projects in the Greater Toronto and Hamilton Area that are in the six-month Transit Project Assessment Process.
