Dundas Bus Rapid Transit

Update – May 3, 2022

The Environmental Project Report (EPR) was available for a 30-day review period from February 23, 2022 to March 25, 2022. On April 27, 2022, the Minister of the Environment, Conservation and Parks issued a Notice to Proceed with the municipal transit project in accordance with Ontario Regulation 231/08. As the final step of the Transit Project Assessment Process (TPAP), Metrolinx and the City of Mississauga have issued a Statement of Completion in accordance with Ontario Regulation 231/08. We have also made available, online, our revised Environmental Project Report (EPR), EPR Errata, and revised Stage 1 Archaeological Assessment.

More information is available on our Environmental Assessment webpage.

Project Overview

Welcome to our online engagement platform for the Dundas Bus Rapid Transit (BRT) Project.

Typically, the Greater Toronto and Hamilton Area welcomes about 110,00 new residents every year and is anticipated to hit a population of over 10 million people by 2041. Growth in our communities means that a reliable transportation system is needed to support the convenient and reliable movement of people as they travel from their homes for work and recreation.



The purpose of the Dundas BRT Project is to evaluate the proposed transit corridor along a 48 km stretch of Dundas Street from Highway 6 in the City of Hamilton through to the Kipling Transit Hub in the City of Toronto, linking Etobicoke and Mississauga City Centres. More than 20 km, of the 48 km municipal transit project would operate in bus lanes or in a dedicated right-of-way, separate from other traffic, allowing faster and more reliable transit connections. 

This round of engagement is focused on the Mississauga East segment as planning has advanced to:  

  • Advance preliminary design and environmental studies by leveraging the Dundas Connects Master Plan study results  
  • Support the City of Mississauga’s funding application to the Investing in Canada Infrastructure Program (ICIP)  
  • Meet the vision for the future of the communities, population and employment growth strategies along Dundas Street within this segment, as outlined in the policy documents, including but not limited to, the City of Mississauga’s Official Plan and the Provincial Growth Plan  

Engagement on Toronto, Mississauga West and Halton and Hamilton will continue through 2022. 

Project Timeline

Graphic displaying the Project Process: Transit Project Assessment Process (TPAP), Preliminary Design (PD), and Preliminary Design Business Case (PDBC). We are currently in the Mississauga East 35 Day Minister’s Review period, during which the Statement of Completion is released. Previous stages of the Project Process are listed as follows: In 2020, project launch and initiation of preliminary environmental studies occurred. This was followed by the first round of Public Engagement in 2021. Next, in 2021, the environmental studied were initiated, the existing environmental conditions studies were completed, the second round of Public Engagement took place and the Notice of Commencement for TPAP, Environmental Project Report and Preliminary Design for Mississauga East documents were produced. In 2022, the third round of Public Engagement took place, followed by the Mississauga East TPAP consultation and documentation, Mississauga East Notice of Completion and the 30-day public review period. These activities are followed by the Mississauga East 35 Day Minister’s Review period, during which the Statement of Completion is released (we are here), and the Preliminary Design for Halton and Hamilton. Continuing in 2022, this will be followed by the fourth round of Public Engagement, the Preliminary Design Business Case, the Notice of Commencement for TPAP, EPRs and Preliminary Design for Toronto and Mississauga West. Nearing the end of 2022, the fifth round of Public Engagement is scheduled to occur, along with the Toronto and Mississauga West TPAP Consultation and documentation release and the release of the Toronto and Mississauga West Notice of Completion. Towards the beginning of 2023, the 30-Day Public Review period is scheduled to occur followed by the final activities, the Toronto and Mississauga West 35 day Minister’s Review and release of the Statement of Completion.

What we Heard at Virtual Public Engagement #2 

Virtual public engagement 2 was held in September 2021. Feedback gathered demonstrated general public support for the Project, preference for Cooksville pinch point Alternative 1 or 3, and strong interest in learning more about progress of the Project, community and property impacts, and connectivity to surrounding infrastructure and services. The public identified:  

A table detailing the main opportunities and concerns that members of the public identified during Round 2 Engagement in September 2021. The public identified opportunities related to the expansion of cycling facilities, reliability of transit services, more stop locations, connectivity to other transit services and creating an efficient transit system while maintaining traffic flow for all road users. The public expressed concerns about potential impacts (e.g., noise, vibration, properties, community and environmental), increased traffic flow on Dundas Street, and preserving existing buildings and community culture in the area.

Opportunities to:

  • Expand and improve cycling facilities on Dundas Street.
  • Provide a reliable transport service as a result of dedicated BRT lanes.
  • Add more proposed stops along the corridor to connect riders to additional destinations (e.g. University of Toronto’s Mississauga Campus, Erindale Park).
  • Connect the Dundas Bus Rapid Transit (BRT) line to other regional and express transit services (e.g., GO Transit, Hamilton Street Railway, Toronto Transit Commission).
  • Create an efficient transit system while maintaining traffic flow for all road users by implementing Alternative 1 at the Cooksville pinch point or implement Alternative 3 to include no left-turns at high-traffic intersections to avoid traffic delays.

Concerns about:

  • Potential noise and vibration impacts.
  • Potential impacts to public and private properties.
  • Environmental and community impacts as a result of project construction and operation.
  • Traffic flow on Dundas Street as a result of modifications to the right-of-way (i.e., adding, removing traffic lanes).
  • Potential for Alternative 4 for Cooksville pinch point to negatively impact BRT service reliability by operating buses in mixed traffic.
  • Preserving the existing buildings and community culture of the surrounding area.


Feedback provided during virtual public engagement 2 has been and will continue to be considered to inform key Project decision-making. The impact of public feedback during the second round of engagement can be directly observed in the development of the Draft Environmental Project Report (EPR) for Mississauga East and the refinement and optimization of design for the Cooksville pinch point and for the corridor outside of the pinch point.

How is the study structured?

The study is structured into the following four areas along Dundas, three Transit Project Assessment Processes (TPAPs) for Toronto, Mississauga East and Mississauga West, and one Preliminary Design Business Case (PDBC).

  • Toronto – Kipling Transit Hub to Etobicoke Creek
  • Mississauga East – Etobicoke Creek to Confederation Parkway (WE ARE HERE)
  • Mississauga West – Confederation Parkway to Ninth Line
  • Halton and Hamilton – Ninth Line to Highway 6 (no TPAP anticipated)

What formal process is followed?

Metrolinx is working with various municipalities to advance planning and design of the Dundas BRT Project, which includes the following key phases:

  • TRAP
  • Preliminary Design (PD)
  • PDBC

In September 2020, Metrolinx completed and published an Initial Business Case (IBC) to assess the need for the Dundas BRT. The document provides an evidence-based assessment of the case for investment in the new rapid transit corridor. The IBC provides the information necessary for decision-makers, stakeholders and the public as an important part of the transparent and evidenced-based decision-making process.

This document includes:

  • A confirmation of the problem and/ or opportunity and identifies a set of investments that could address them
  • Provides a high-level range of varying investments that could be implemented
  • Gives insights and recommendations for future work

The IBC evaluated the early-stage feasibility of the Dundas BRT by examining the strategic, economic, financial and deliverability and operations cases. The IBC found that the BRT could:

  • Accommodate more than 30,000 new net daily riders
  • Benefit traffic flow resulting in between 345,000 and 555,000 hours of decongestion benefits per year
  • Decrease greenhouse gas emissions by between 100,000 to 600,000 tonnes per year
  • Unlock economic and regional development by connecting rapid transit to 230,000 to 465,000 jobs found within 2 kilometres of the catchment area (approximately a 10-minute walk)
  • Offer frequent rapid transit service to 600,000 to 1,000,000 people living within 2 kilometres of the corridor
  • Reduce transit commute times along the corridor by approximately 14 minutes on average

The Dundas BRT Initial Business Case considered the following three service options. All the options perform well and show a robust case for investment, demonstrating the benefits of service integration on the Dundas corridor to support BRT infrastructure investment.

What is a stop?

A stop is a designated area where the Dundas BRT will stop to pick up and drop off passengers. The scale and amenities of each stop will reflect the level of predicated usage or existing infrastructure in the area.

Potential amenities of the Dundas BRT stops include:

  • Access ramp and railings
  • Tactile warning strips (e.g., textured ground surfaces for the visually impaired)
  • Location of stop name and wayfinding signage
  • Next bus information
  • Fare collection
  • Art and cultural heritage elements
  • Benches and seating
  • Service maps
  • Weather protection
  • Garbage bins

What is the distance between each stop?

When selecting BRT stop locations, access must be balanced with travel time. Stop locations are based on factors as follows:

  • Locations identified as part of the Dundas Connects Study and the Initial Business Case (IBC);
  • Current transit facilities and intersecting bus routes that form the basis of a feeder network;
  • Distance between stops; and
  • Land use and major trip generators.

1075 meters distance between stops, 8 stops in Mississauga East.

The distance between each Dundas BRT stop location will vary, depending on the city being travelled through. Increased spacing between Dundas BRT stops will allow for fast and reliable service through the corridor.

Dundas BRT stops in Mississauga East

Since the last round of public engagement, work has advanced on establishing the proposed stop locations and potential amenities. Eight stop locations within Mississauga East have been identified, each of which has been informed by the above mentioned criteria.

As preliminary design work for Toronto, Mississauga West and Halton and Hamilton is still underway, more information related to proposed stop locations and potential amenities in these areas will be presented during a future Public Information Centre.

Provisions for future electrification technology are being considered in the planning of the corridor. This may be considered as the existing electrification technology allows transit vehicles to run smoothly without the use of fossil fuel, providing a green mode of transportation.

Instead of fueling each morning/evening, electric buses charge overnight at bus depots and, if required, schedule midday recharging layovers at garages or pass through discrete charging stations at potential layover locations during the day to ensure a smooth ride through the Dundas Street corridor.

Why electrification?

When compared to diesel or compressed natural gas, electric buses:

  • Offer a smoother, quieter ride
  • Emit minimal or zero carbon or greenhouse gases (GHGs), helping to meet targets set out in Ontario’s Climate Change Action Plan (CCAP) of reducing overall GHG emissions by 40% by 2030 and the City of Toronto’s goal to ensure 100% of transit vehicles transition to low-carbon energy by 2050

What could electrification look like?

Electrification may look similar to Le Corbusier BRT or the Laker Line BRT shown below.

MiWay Electrification Pilot

Did you know?

  • MiWay is currently conducting studies and participating in a hydrogen fuel cell* electric bus pilot project to understand how hydrogen-electric technology can help advance Mississauga’s commitment to a zero-emission bus fleet.
  • MiWay will add new bus technologies, which already include 11 new, second generation hybrid-electric articulated buses with more planned for delivery in 2021, to stay up to date with industry trends, while adjusting the long-term bus replacement plan to effectively manage the integration of new technology as older-model buses complete their lifecycle.

* Hydrogen fuel cell technology requires considerable upfront costs and increased operating costs when compared to electric technology. However, costs associated with hydrogen fuel cell technology is rapidly decreasing.
