Sunningdale Road Environmental Assessment


Sunningdale Road is a two-lane street in north London where traffic volumes are steadily increasing, and road improvements are required to meet travel demand. Major intersections along the road are already beginning to experience operational challenges due to high traffic volumes and turning movements, including at Wonderland Road, Richmond Street, and Adelaide Street, where the existing conditions warrant improving the intersections.

This Environmental Assessment was initiated to explore solutions to address challenges along Sunningdale Road, between Wonderland Road North and Adelaide Street North, including safety, traffic congestion, comfort and convenience, speed and travel time.

Through the Environmental Study Report, a number of improvements were recommended for Sunningdale Road that aligned with the Transportation Master Plan, including:

  • widening the road from two to four lanes to meet the projected transportation requirements in the area, with auxiliary turn lanes at intersections where warranted
  • intersection improvements at two major intersections (Wonderland Road and Adelaide Street)
  • improving the Richmond Street intersection by adding left/right turn lanes
  • cycling infrastructure throughout the Study Area
  • sidewalks for both sides of Sunningdale Road
  • a three-metre pathway under the Medway Creek Bridge to allow future connections to the east path system

Current status

The Environmental Assessment is complete, and Council approved the plan in June 2012. The timing for construction is currently being reviewed.

Study Area

The study area is Sunningdale Road from Wonderland Road North to Adelaide Street North. For more information, please contact Michelle Morris at or 519-661-2489 extension 5806.


Project Timeline

August 2009: Start of Environmental Assessment

The City sent out a notice of commencement to residents, business owners and interested stakeholders to notify them of the Environmental Assessment's start.

October 2009: First Public Information Centre

A Public Information Centre was scheduled for October 2009 - interested parties were encouraged to attend. They provided comments specific to the potential realignment of Commissioners Road West to the project team, which were critical to the development of this environmental assessment.

June 2011: Second Public Information Centre

A Public Information Centre was scheduled for November 2011. The team provided all interested parties with an update on the project and listened to feedback that was critical to shaping the recommendations provided by the Environmental Study Report.

June 2012: Environmental Study Report completed

The Environmental Assessment is now complete, and Council approved the plan in 2012.

2021 - Current: Detailed design

The project is now in detailed design.
