Network-Wide Structures Project - Your Feedback

A project of this size and complexity means that changes will occur in communities and some communities close to where infrastructure is being delivered may feel impacted by it. Hearing from you is important to us. We want to make sure we are delivering maximum results with minimum disruption to the community.

The table below provides a snapshot summary of the main topics we've heard since Round 1 of public consultation and what we are doing about it. The full Round 1 Engagement Report is available here.

What We Heard
What We’re Doing About It

Concerns about active transportation and traffic impacts of the proposed grade separations

Metrolinx has developed a conceptual design to determine the optimal configuration of the proposed infrastructure, reviewed background information, and conducted field investigations to determine baseline traffic conditions. This information has been used to inform the traffic impact assessments and develop mitigation measures to address traffic and active transportation impacts.

To maintain pedestrian and cyclist connectivity during construction, Metrolinx will provide well connected, clearly delineated, and appropriately signed walkways and cycling route options, with clearly marked detours where required. Where regular access cannot be maintained, alternative access and signage will be provided.

Metrolinx will also consult with local transit agencies to establish a suitable mitigation strategy for implementation in advance of any potential service disruptions.

Metrolinx will also develop a Traffic Control and Management Plan prior to construction to maintain reasonable access through work zones, to the extent possible.

Traffic signal timing optimization may be assessed/implemented to increase capacity of affected intersections and to aid in the movement of traffic and would be determined through coordination between Metrolinx and the municipality.

Concerns about impacts to properties from the design of the grade separation

As the project progresses through conceptual design, Metrolinx is working to confirm property requirements to the greatest extent possible in this preliminary phase. Specific property requirements will be confirmed during detailed design. Where access to property is required, ongoing consultation with affected landowners will help identify appropriate site-specific mitigation measures.

Metrolinx will strive to locate construction staging and laydown requirements in areas that minimize adverse local effects.

Metrolinx has conducted a Land Use & Socioeconomic Impact Assessment study to assess potential impacts and propose appropriate mitigation with existing land uses. Preliminary findings can be found here: (insert link to panels)

Concerns about the number of road lanes during and after constructions

Metrolinx is developing a conceptual design in consultation with municipal and regional stakeholders in order to determine the optimal configuration of the proposed infrastructure.

Find out more in the Proposed Infrastructure section.

Interest to learn about the anticipated construction timeline

Construction for these grade separations is estimated to begin in 2024.

The GO Expansion Program held a virtual open house as part of Round 2 of public consultation from August 18 to September 1, 2020. Although Round 2 focused on gathering feedback for the three TPAPs: New Track & Facilities, Scarborough Junction Grade Separation, and Stouffville Rail Corridor Grade Separations, participants also asked about work that is part of the Network Wide Structures project. The table above under Public Consultation Round 1, captures the summary of main topics heard from February 2020 to Fall 2020. The Round 2 Engagement Report is available here.

Round 3 of public consultation for the GO Expansion program was held online from November 27 – December 11, 2020.

New information that was presented in Round 3 included:

  • Updated design for the McNaughton Road grade separation, as well, as the identified potential impacts and proposed mitigation measures. Read more about the McNaughton grade separation.
  • The table below provides a snapshot summary of the main topics we've heard in Round 3 of public consultation and what we are doing about it.
What We Heard
What We’re Doing About It

Concerns about visual impacts of the proposed McNaughton Rd road overpass

The road over rail grade separation at McNaughton Road was selected as the proposed design as it provides fewer technical challenges as compared to the rail over road option.

In 2019 Metrolinx conducted an options analysis to determine the appropriate type of grade separation (overpass or underpass). We analyzed impacts to stakeholders, local setting, public realm, property impacts, utilities, engineering constraints, environment, operations and maintenance, capital costs and benefits. The results of this analysis concluded that a road overpass is the most feasible option considering all of these factors. By contrast, a road underpass presents a number of challenges. For one thing, the existing road profile places the rail crossing at a lower elevation than the road. Given the proximity to Maple GO, the track cannot be raised, and as a result, to accommodate an underpass the section of McNaughton Road from Keele Street to Rodinea Road/Troon Avenue would need to be significantly lowered through excavation. This would result in the disposal of large quantities of earth, and with substantial lengths of retaining walls required to limit property impacts. In addition, another significant factor inhibiting the road underpass is that the groundwater levels in the area could require extensive excavation and dewatering in order to make it safe to build the underpass. This would result in additional infrastructure requirements, including pumping stations and associated utilities that would ultimately lead to additional property impacts within the local community. Lastly, underpass option would also require a track diversion, resulting in additional property impacts.

Metrolinx will work with the City of Vaughan regarding the aesthetic and landscaped embankment proposed on the south side, to soften visual impact.

Concerns about traffic impacts to Hill Street and Eagle Rock Way

The proposed grade separation at McNaughton Road is proposed to remove vehicular exit onto McNaughton Road.

The impact this would have on local traffic is something that Metrolinx has undertaken as part of the McNaughton Road Grade Separation Significant Environmental Project Report (EPR) Addenda. As part of construction staging, the right-out only exit from the GO parking lot onto McNaughton Road is to be permanently closed, while alternative access via Eagle Rock Way on the south side is to be maintained. Ultimately, the proposed grade separation will not result in changes to the traffic volumes along McNaughton Road, nor will the proposed grade separation increase the capacity of the roadway as it will maintain two lanes in each direction similar to the existing configuration. As we move closer to construction, Traffic Control and Management Plan(s) will be developed in collaboration with the City of Vaughan to maintain reasonable access through work zones, to the extent possible. As part to those plans, mitigation measures such as signal-timing optimization may be implemented through coordination between Metrolinx and the municipality as part of the detailed design and implementation phases.

Consider providing wider sidewalks or a multi-use path (MUP) on the north side of the proposed McNaughton Road grade separation

Metrolinx is proposing two multi-use pathways as part of the proposed grade separation: one on the south side of the elevated McNaughton roadway and one at grade on south side of McNaughton Road to provide connection to the Maple GO Station Platform.

Metrolinx is currently in discussion with municipal stakeholders on a proposed option for a pedestrian connection on the north side of McNaughton Road. As we are in the early design stage for this project, the community will be kept informed of any developments.

Find out more by viewing the infrastructure panels.

Consider providing a glass noise wall on the proposed McNaughton Road grade separation to mitigate noise impact from cars and trucks

Metrolinx has conducted studies to ensure that the impacts of the proposed grade separation are mitigated, including a Traffic Impact Assessment (TIA). As a result of the TIA, the road will maintain two lanes in each direction, similar to the existing configuration. Therefore, there will be no changes to traffic volume and no measurable change in vehicle noise from traffic along McNaughton Road as a result of the grade separation.

However, this is a preliminary study and there are some impacts that require further analysis as the design is further fleshed out. A detailed analysis of the changes in noise levels resulting from the grade separation will be completed at the detailed design. For more information on operational noise and vibration mitigation measures, including proposed noise walls along the corridor, please visit the noise and vibration and air quality page.
