Environmental Project Report update

The Environmental Project Report (EPR) was available for review for a 30-day review period from January 21, 2022 to February 22, 2022. On March 28, 2022, the Minister of the Environment, Conservation and Parks issued a Notice to Proceed with the transit project in accordance with Ontario Regulation 231/08. As the final step of the Transit Project Assessment Process (TPAP), Metrolinx and Durham Region have issued a Statement of Completion in accordance with Ontario Regulation 231/08.

Environmental Assessment

A Minister's Notice to Proceed on the project was issued on March 28, 2022 for a bus rapid transit corridor serving Scarborough, Pickering, Ajax, Whitby and Oshawa. The 36-kilometre corridor will include but is not limited to dedicated bus lanes, bus stops, centre medians and multi-use paths.

The Statement of Completion of the Transit Project Assessment Process was issued on March 31, 2022. This means planning expansion and new infrastructure projects to serve our growing population into 2041 and beyond. To help people get to where they need to go, Metrolinx is working to bring a more frequent and reliable transit service to Durham Region and the City of Toronto through the Durham-Scarborough Bus Rapid Transit (DSBRT) project.

To get there, the project was assessed following the Transit Project Assessment Process (TPAP).

The TPAP is a focused impact assessment created specifically for transit projects, regulated under Ontario’s Environmental Assessment Act. The TPAP is a focused impact assessment process for Ontario transit projects that includes consultation, assessment of potential environmental impacts, an assessment of measures to mitigate negative impacts, and documentation. The process is prescribed in Ontario Regulation 231/08 – Transit Projects and Metrolinx Undertakings, made under the provincial Environmental Assessment Act.

The TPAP is a regulated timeline of up to 120 days to prepare an Environmental Project Report (EPR) and consult with interested persons, including regulatory agencies and Indigenous Nations. Due to the regulated timeline of the TPAP, pre-planning activities occur prior to the formal commencement of the TPAP to begin preparing environmental studies and understand the interests of stakeholders.

Pinch Points

Explore the Pinch Point study areas and the pros and cons for each

Pinch Point #1 study area:

Key considerations for the Ellesmere Road pinch point are:

• Minimal property acquisition required to achieve Official Plan right-of-way

• High forecasted traffic volumes in 2041

• Minimal natural heritage features and cultural heritage resources

Technically Preferred Option: Centre-median (6 Lanes)

Widen to add two dedicated transit lanes and maintain the current number of general traffic lanes. (Cross-sections are conceptual.)


• Provides the highest priority for transit, improving speed, reliability, comfort and convenience

• Maintains existing traffic capacity

• Provides opportunities to improve existing active transportation network

• Local transit can serve stops from curb lanes between rapid transit stops


• Requires all left-turns to occur at signalized intersections

• Limited potential impacts to a few cultural heritage resources
