What we heard

From March 26 to April 17, 2026, we received more than 330 survey responses as part of the online Public Information Centre (PIC) for the James Snow Parkway Extension Municipal Class Environmental Assessment (MCEA) Study Addendum.

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

We have summarized what we heard and have provided additional information below 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.

What is the purpose of the James Snow Parkway Extension MCEA Addendum?

The previous MCEA Study was completed by the Town of Milton in 1999 for James Snow Parkway from Highway 401 to Neyagawa Boulevard and included a new bridge crossing over East Sixteen Mile Creek. The section of James Snow Parkway north of Britannia Road has been constructed and is a Regional Road. 

The Region’s Transportation Master Plan to 2031 identified the James Snow Parkway extension from Britannia Road to Highway 407 ETR as a six-lane corridor. To complete the southerly section of the James Snow Parkway as recommended in the 1999 Environmental Study Report, Halton Region is now preparing an MCEA Study Addendum Report to address the change from a four-lane road in a 35m right-of-way to a six-lane road in a 47 m right-of-way, and to update mitigation measures to reflect the current environmental setting.

How will the James Snow Parkway Extension support future travel demand?

The James Snow Parkway Extension will be a six-lane corridor and is intended to support existing and future north-south travel demand between the Towns of Milton and Oakville, by connecting the existing James Snow Parkway (Regional Road 4) at Britannia Road in Milton, to Neyagawa Boulevard (Regional Road 4) at Highway 407 in Oakville. 

The existing sections of James Snow Parkway, north of Britannia Road to Tremaine Road, are also planned to be widened to six lanes. The Region is undertaking separate MCEA Studies for these improvements. For more information on these ongoing studies, please visit the Municipal Class Environmental Assessment Studies webpage. 

What type of active transportation facilities are proposed along the corridor?

A combination of cycle tracks and sidewalks are proposed along the James Snow Parkway Extension. All proposed active transportation facilities will be physically separated from vehicle lanes and located “in-boulevard” (i.e., between the curb and property line). For more information about the specific facilities in each section of the corridor, please refer to Video 3 in the PIC materials. 

How is transit being considered as part of this MCEA Study Addendum?

The James Snow Parkway corridor is identified as a future Transit Priority Corridor in the Region’s Integrated Master Plan (2026), and the preliminary preferred design includes the protection for transit supportive infrastructure. For more information, visit the Integrated Master Plan webpage.

Has the Region considered roundabouts instead of signalized intersections?

Yes, a detailed transportation assessment was conducted to evaluate future transportation conditions and needs throughout the corridor. The assessment examined all potential intersections in the study area, considering both traffic signals and roundabouts as potential traffic control types. Traffic signals were identified as the preferred option for intersections along the proposed James Snow Parkway Extension. 

How are noise and air quality impacts being considered?

Noise and air quality assessments are underway to evaluate and predict how the proposed road extension will affect noise levels and air quality. The findings from both the noise and air quality assessments will be documented in the MCEA Study Addendum.

How are impacts to the natural environment being considered?

Halton Region is undertaking studies that consider the natural environment, archaeological and cultural heritage resources, drainage, and hydrology. The recommendations from these studies, including mitigation measures, will be documented as part of the MCEA Study Addendum. During detailed design, Halton Region will obtain the necessary environmental permits and approvals to support implementation of the project.

Will the corridor accommodate truck traffic?

Halton’s Regional Road system connects rural and urban centres while providing connections to the provincial highway system and the local road network. 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 wide turns at intersections. 

What are the next steps for implementation?

The MCEA Study Addendum is anticipated to be completed in Fall 2026. Following the completion of the Addendum, the project will continue into the Detailed Design and Approvals phase, which is a multi-year process, followed by the Construction phase.
