Thompson Road Environmental Assessment

Consultation has concluded

About the Study

What is it?

The Town of Milton is carrying out a Municipal Class Environmental Assessment (Class EA) Study for the road improvements on Thompson Road, between Louis Saint Laurent Avenue and Britannia Road. The need for these roadway improvements has been identified in the Boyne Survey Secondary Plan. WSP has been retained to assist with the study; the study area is shown on the map below.



Thompson Road, between Louis Saint Laurent Avenue and Britannia Road, is currently a two-lane rural road with a posted speed of 60 km/hr. This portion of Thompson Road is designated in the Town of Milton's Official Plan to be a minor arterial road with a 35 metre right-of-way, and is within the Boyne Survey Secondary Plan Area. Lands adjacent to Thompson Road are designated to be residential and office areas, with “Secondary mixed-use nodes” (i.e. community facilities including significant commercial facilities or subject to provisions of high density residential) identified on Thompson Road, south of Louis Saint Laurent Avenue.

Why is Milton doing this Class EA Study?

The Class EA reviews available background information, identifies problems and opportunities, assesses alternative solutions and generates preliminary design concepts to address the potential environmental effects and determines the preferred alternative.

Local residents and interested members of the public have an opportunity to review and comment on the alternatives under consideration, the evaluation process and the next steps in the study.

The community is encouraged to submit comments by Thursday, December 13, 2018.

UPDATE FEBRUARY 25, 2019: The comment and question period has now closed. All comments will be considered and documented as part of the final Environmental Study Report (ESR) for the project, and answers to specific questions posted in the Q&A section have been provided. Please see the "Key Dates" section for information regarding the next steps in this project.

  • Are you planning to do something for traffic flow between Main Road and Laurier on Thompson road? Traffic lights on this corridor are ill planned and they cause traffic jam in rush hours.

    Mrehman asked 6 months ago

    Thank you for taking the time to review the Thompson Road Online Public Information Package and Technically Preferred Alternative Plan on the Town’s website and providing comments.

    The section of Thompson Road between Main Street and Laurier Avenue falls outside of the Study Area for this Town of Milton EA. The Town of Milton continually monitors traffic operations along the Thompson Road corridor, if you have a specific concern please contact Heide Schlegl, Manager Traffic at 905-878-7252 ext. 2506 or by email at heide.schlegl@milton.ca

    If you have any further questions or comments please do not hesitate to contact the Project Team.


  • Hello, I reviewed the technical drawing. Will the multi use pathway be for cyclists and pedestrians? Will the cycling portion of the pathway be painted in a different colour such as green? Why can’t a separate from pedestrian cycling track be included in this project?

    gddaichan asked 6 months ago

    Thank you for taking the time to review the Thompson Road Online Public Information Package and Technically Preferred Alternative Plan on the Town’s website and providing comments.

    The provision for pedestrians and cyclists includes a 1.2 metre on-street bike lane and a 3 metre multi-use path on both sides of the road. Landscaping components such as greenery, signage and other visual elements will be developed as part of detailed design. The planning of active transportation facilities (sidewalks and bike lanes) are in accordance with the Town of Milton Trails and Cycling Master Plan and are designed to the Town's road standards.

    If you have any further questions or comments please do not hesitate to contact the Project Team.


  • What alternatives are under consideration?

    RHULL asked 7 months ago

    Thank you for taking the time to review the Thompson Road Online Public Information Package and Technically Preferred Alternative Plan on the Town’s website and providing comments.

    The alternative solutions that were considered were:
    1. Widen by the centreline
    2. Widen to the east only
    3. Widen to the west only

    The analysis and evaluation of the design alternatives were based on a set of evaluation criteria that included social/community, cultural environment, natural environment, transportation/technical, and cost and construction factors.

    Based on findings from the analysis and evaluation of alternatives using the factors listed above, widen by the centreline was identified as the preferred alternative solution. 

    Though widening by the centreline was identified as the preferred solution, based on input from adjacent land owners, the preliminary plan has been modified in the localized area north of Britannia Road where Thompson Road will be widened to the west only, to minimize property impact to the farm property on the east side. Recognizing that the existing constraints along Thompson Road vary, a ‘Best Fit’ approach was developed which will allow for flexibility in widening to the east or west, depending on surrounding constraints.

    The preferred alternative will be carried forward for detail design and construction. Timing of the detail design and construction of the new four lane road will be subject to annual council review and funding availability.
