Dundas BRT Round 3 Engagement - Preliminary Design

Land Acknowledgement

Metrolinx acknowledges that it operates on the traditional territory of Indigenous Peoples including the Anishnabeg, the Haudenosaunee and the Wendat peoples.

In fact, the Dundas Bus Rapid Transit Project is proposed on lands covered by Treaty 3, 1792, the Head of the Lake Purchase 1806, and the Brant Tract, 1795, Treaty 22 & 23, 1820 and Treaty 13, 1805 with the Mississaugas of the Credit First Nation as well as the Fort Albany/Nanfan Treaty of 1701 with the Haudenosaunee.

Metrolinx is committed to building meaningful relationships with Indigenous Peoples, and to working towards meaningful reconciliation with the original caretakers of this land.

What is the preliminary design process?

The preliminary design (PD) process bridges the gap between the design concept and detailed design of a project. 

The PD phase is formed from the Dundas Connects Master Plan and the Metrolinx Initial Business Case. In this phase, the Project Team will use the analyses of technical and environmental studies and public engagement to refine the Dundas Bus Rapid Transit (BRT) design to a 30% design level. The 30% design will seek to further refine corridor infrastructure such as lane widths, buffers, boulevards, active transportation facilities and grading limits in order to reduce impacts identified in the TPAP. Outcomes from the PD will inform the Preliminary Design Business Case (PDBC). 

The PDBC takes the recommended option of the Initial Business Case and reviews different approaches to refine and optimize it. The PDBC occurs during the Preliminary Design stage, along with the TPAP. It leads to a single preferred option for final development in the Full Business Case (FBC). The Dundas BRT PDBC evaluates the project across strategic, economic, financial and deliverability and operations cases. It also sets out the costs, benefits, risks and barriers of the project, which will assist Metrolinx and its partners in developing future phases of work on the corridor. 

More information on the study process is available on the Environmental Assessment webpage. 

Mississauga East – Next Steps

The optimized Alternative 1 – Full median Bus Rapid Transit (BRT) widened about centreline, will be carried forward to 30% Preliminary Design and further refined.
