Phase 1: Wyndham Street Reconstruction

About the Project

The Phase 1: Wyndham Street Reconstruction project is the first detailed design and construction project in the Downtown Infrastructure Renewal Program. This work focuses on the reconstruction of Wyndham Street, from Wellington Street East to Woolwich Street. This project will also include the reconstruction of St. George’s Square. Construction began in April 2026. During construction:

  • All underground sewers and watermains will be replaced and upgraded,
  • The roads, sidewalks and cycling facilities will be upgraded and rebuilt, and
  • The surface will be replaced with updated and modernized streetscaping.

Third-party utility work (such as gas and electrical work) is also underway. More details about this work is available.

We’re committed to working with the Downtown community to plan and schedule this work in a way that limits the impact to daily life as much as possible. Together, we’ll create innovative solutions to keep our historic core thriving during construction.

Three street segments are highlighted in different colors: a yellow section from Woolwich Street to Macdonell Street labeled “September 2026 to November 2027,” a green section from Macdonell Street to Quebec Street labeled “March 30, 2026 to November 2027,” and a blue section from Quebec Street to Wellington Street East labeled “March 30, 2026 to July 2026.”

Project Progress

Wyndham Street began construction on March 30, 2026. The first section of Wyndham Street to be impacted is from Wellington Street East to south of the Macdonell Street intersection. The intersection of Macdonell Street and Wyndham Street will remain open for traffic on Macdonell except for one four-week period during the summer, beginning July 19. 

Wyndham Street from Wellington Street East to the north side of Carden Street is expected to reopen to vehicular traffic on July 19.

Getting Guelph Through Construction: Construction Mitigation Plan

Infrastructure reconstruction in a busy Downtown creates challenges for businesses, residents, and visitors due to disruptions to normal business activities, noise, dust, traffic management, and other factors beyond what is experienced on typical reconstruction projects.

The construction mitigation plan helps to reduce the impact of construction on Downtown businesses, residents, and visitors. The plan’s four key elements are:

  • Communication and information sharing
  • Direct construction support
  • Business support plan
  • Construction pace, phasing and staging

Parking and Access Downtown

St. George’s Square

St. George’s Square will be revitalized as a central gathering space and hub for community programming. On December 16, 2025, the final plan for St. George’s Square was approved by Council.

Community Engagement

We are committed to communicating with businesses and residents about this project. We encourage you to reach out to our project team member at any time with questions or comments.

We’re planning on hosting an open house for the Wyndham Street reconstruction; one in early 2026 regarding the construction mitigation efforts planned for this program of work.
