The Dundas BRT - Pinch Points - Erindale Valley Area

← Return to the Dundas BRT map

Erindale Valley Pinch Point

The Erindale Valley area is constrained due to the need to protect the natural environment of the Credit River Valley and Erindale Park. There are also several heritage sites that need to be considered between Mississauga Road and The Credit Woodlands.

Preliminary design – pinch points 

As work for Mississauga East is advancing ahead of other areas along the Dundas BRT corridor, an additional evaluation process has been applied to the Cooksville pinch point to meet the requirements of the Investing In Canada Infrastructure Program (ICIP). All pinch points along the corridor will be assessed within the PDBC framework outlined below. 

The following slides document the feedback heard and the steps taken by the project team to design a preferred solution for the Dundas BRT corridor.  

During the last round of engagement, a pinch point was also identified in Toronto, on Dundas Street between The East Mall and Aukland Road. Technical work on this pinch point is ongoing and will be presented during the next round of engagement later this year. 

How are pinch points evaluated? 

In addition to the evaluation criteria identified as part of preliminary design, pinch point evaluation considers the technical categories below pertaining to the natural, cultural and built environment in each location. Following the first round of engagement, the below pinch point considerations were updated as a result of feedback provided by the public. Feedback provided identified environmental considerations as most important, followed by geometrics/infrastructure, traffic and property considerations and also contributed to additional evaluation criteria including capital cost, transit service reliability, cyclist and pedestrian accessibility and connectivity and road safety. 

Preliminary Designs

Alternatives: Dundas Street in Mississauga – Erindale Valley pinch point

Key considerations for the Erindale Valley pinch point include:


  • Property acquisition required beyond the Official Plan right-of-way (ROW) to accommodate all contemplated infrastructure needs (dedicated BRT guideway, four general purpose lanes, cycle tracks, sidewalks and amenity/utility space)  

  • Numerous buildings located close to the property/ROW line  

  • Significant natural heritage features  
  • Numerous cultural heritage resources and landscapes

During round 1 engagement, members of the public identified:


Opportunities to:

  • Implement the Dundas BRT project as part of the City of Mississauga’s Dundas Connects Master Plan

Concerns about:  

  • Cycling infrastructure and safety  

  • Pedestrian infrastructure and safety  
  • Environmentally sensitive areas  
  • Dedicated transit lanes  
  • Landscaping (aesthetics) 

The project team arrived at two alternatives and are reviewing each for potential benefits and drawbacks. Both alternatives will also be analyzed against the same criteria used to determined the best performing alternative for the Cooksville pinch point: 

Alternative 1: Reversible BRT Lane


  • Lower capital cost with only a single dedicated transit lane  
  • Fewer property impacts and building displacements  
  • Minor impacts to natural features  


  • Does not maintain continuity of full BRT lanes through corridor 
  • Less reliable due to general traffic impedance with notable transit delays 
  • Potential for residential and built heritage resource displacements

Alternative 2: Full Median BRT (to the North) 


  • Maintains continuity of median BRT 
  • Provides a full multi-modal cross section, including buses, auto traffic, pedestrians and cyclists 
  • Provides transit service reliability with less potential for service interruptions or delays 


  • Higher capital cost to implement  
  • Potential for property impacts along the south and north sides of Dundas Street  
  • Potential for commercial, residential and heritage resource property displacements  
  • Increased impacts to natural features
