Online Consultation: New North Regional Road Corridor Municipal Class Environmental Study

Study overview

Halton Region is carrying out a Municipal Class Environmental Assessment Study for a New North Regional Road Corridor between Fifth Line and Sixth Line from Britannia Road (Regional Road 6) to Steeles Avenue (Regional Road 8) in the Towns of Halton Hills and Milton.

The study is examining a wide range of road improvements including a new corridor. In addition, the study will consider active transportation, traffic and intersection operations, structural, drainage, and cross-sectional requirements. Social, cultural and environmental impacts of the improvements will be assessed and evaluated through the study.

What we heard

From May 28 to June 18, 2026, we received more than 470 responses as part of the first online Public Information Centre.

Thank you to everyone who provided valuable input to the study!

We have summarized what we heard and have provided additional information as follows to address the common themes raised. We invite you to review the information and contact the project team if you have any follow-up questions or comments.

How was the need for a new corridor identified? 

The Region’s 2011 Transportation Master Plan identified the need for the New North Regional Road Corridor from Britannia Road to Steeles Avenue with a new interchange at Highway 401 to address future travel demand to 2031 and beyond. This need was reaffirmed through the 2026 Integrated Master Plan and subsequently reaffirmed by analyses completed as part of this MCEA study. 

How will the New North Regional Road Corridor support future travel demand? 

The new Regional Road will add north-south traffic capacity as well as improve connectivity to Highway 401. It will also serve planned development as identified in the Premier Gateway Employment Area Land Use Plan (external link) (Town of Halton Hills), the Derry Green Corporate Business Park Secondary Plan (external link) (Town of Milton), and the Britannia Secondary Plan (external link) (Town of Milton).

How was the location of the New North Regional Road determined?

The location of the New North Regional Road Corridor was determined using an evaluation of the three alternative corridor concepts identified in Video #2: Alternative Planning Solutions, Alternative Corridor Concepts, Preliminary Recommendations, and Next Steps (YouTube video link).

How are natural environmental impacts being considered?

Halton Region is undertaking studies that consider the natural environment, archaeological and cultural heritage resources, drainage, and hydrology. The findings from these studies have informed the development of the alternative corridor concepts, including identifying mitigation measures. These will be documented as part of the MCEA study and included in the Environmental Study Report. During detailed design, Halton Region will obtain the necessary environmental permits and approvals to support implementation of the project.

How are property impacts being considered?

Minimizing impacts to surrounding properties is a key design consideration. Phase 3 of the MCEA process will include the evaluation of design alternatives for the recommended corridor concept, which will consider impacts to property and access. These analyses will inform the evaluation of design alternatives. The results of the Phase 3 work will be presented at a future PIC, at which time, the preliminary preferred design will be presented for public and stakeholder review. 

How are noise and air quality impacts being considered?

Noise and air quality assessments will be undertaken to evaluate and predict how the proposed Regional Road will affect noise levels and air quality The findings from both the noise and air quality assessments will be documented in the Environmental Study Report, which will be published at the completion of the study.

How is the Region considering nearby road infrastructure projects?

The study is being coordinated with nearby Regional and Municipal Road infrastructure projects, including:

• Trafalgar Road MCEA Study (Halton Region)
• North Halton Coordinated MCEA Study (Halton Region)
• James Snow Parkway Extension MCEA Addendum Study (Halton Region)
• Main Street East MCEA Study (external link) (Town of Milton)
• Sixth Line Road MCEA Study (external link) (Town of Milton)

How will the project be implemented since Fifth Line is a Municipal Road owned by the Town of Milton?

The Region is working closely with the Town of Milton on the MCEA study recommendations. 

How does Highway 413 impact this this project?

The Highway 413 project is located to the east of the study area along Highway 401. The project team will continue to coordinate with the Ministry of Transportation (MTO) on the integration with Highway 401 with a potential new interchange connection, which is subject to MTO approval.

How is transit being considered?

In November 2025, through PW-35-25, Regional Council adopted the recommended servicing strategies to support growth in Halton Region to 2051 as set out in the Halton Region Water, Wastewater and Transportation Integrated Master Plan. While the New North Regional Road is not identified as a Transit Priority Corridor in the Master Plan, adjacent Regional Roads, including James Snow Parkway, Steeles Avenue, Britannia Road, Trafalgar Road, and Derry Road are identified as Transit Priority Corridors by year 2051.  For more information, visit the Integrated Master Plan webpage.

How is active transportation being considered as part of this study?

The New North Regional Road will include pedestrian and cycling facilities along the corridor to improve active transportation connectivity. All proposed active transportation facilities will be physically separated from vehicle lanes and located between the curb and property line. More detailed information regarding the type and design of active transportation facilities will be presented at the second Public Information Centre. 

What road safety measures have been considered?

Safety remains our top priority for all transportation improvements. The next phase of the MCEA study will include the evaluation of design alternatives for the recommended corridor concept, which will consider cross-section options including the type and location of active transportation facilities, and design solutions at intersections. 

What is being done to address speeding in the area?

Speed limits within the Regional Road system are reviewed on an annual basis so that they are appropriate for current conditions. Concerns related to speeding and requests for additional enforcement can be reported through the Halton Regional Police Service's Road Watch program (external link).

How will truck traffic be accommodated in the corridor?

All Regional roads are designed to support all modes of travel, including trucks, with some seasonal restrictions. For example, Regional roads are designed to support the weight and size of transport trucks and accommodate turning movements at intersections.

What are the next steps for implementation?

This MCEA Study is anticipated to be completed in fall 2027. Following the completion of this MCEA, the project will continue into the Detailed Design phase, followed by the Construction phase.
