Online Consultation: Steeles Avenue Municipal Class Environmental Assessment (MCEA)


Halton Region is asking for input on the preliminary preferred design for Steeles Avenue in the Town of Milton. This is the second Public Information Centre (PIC) for this study, as part of the Schedule C Municipal Class Environmental Assessment (MCEA) process.

About the study

Study area


Study overview


To address future travel demand to 2031, there is a need to make road improvements to Steeles Avenue between Tremaine Road and Industrial Drive. The potential improvements are anticipated to include:

  • widening the road to four lanes;
  • active transportation facilities (on-road bike lanes and multi-use pathways);
  • a new underpass as part of a Canadian Pacific Rail grade separation;
  • intersection improvements (for example, new traffic signals, roundabouts, turning lanes); and
  • landscaping and street lighting.  

The study is being conducted in accordance with the planning and design process for Schedule C projects as outlined in the Municipal Class Environmental Assessment (October 2000, as amended 2007, 2011 and 2015), which is approved under the Environmental Assessment Act, RSO. 1990.

Reasons for the study


Halton Region is carrying out this study in accordance with the MCEA process to:

  • address future travel demand in the Town of Milton to 2031; and
  • support all modes of transportation (waking, cycling, transit and automobiles) and ensure safety for all road users.

Technical documents

  • Preliminary preferred design for Steeles Avenue MCEA Study (PDF file):
    • The design is considered ‘preliminary’ until public, agency and Indigenous community feedback is received through this second PIC.
    • Key features of the Preliminary Preferred Design include:
      • a culvert/small bridge which will convey a small creek under Steeles Avenue just east of Tremaine Road;
      • an underpass at the CP Rail line;
      • a roundabout or a signalized intersection to provide a connection to existing Steeles Avenue and the neighbourhood of Peru, as well as new driveway access to the Milton Banquet and Conference Centre; and
