Main Street Unionville Restoration
Project Description
Main Street Unionville is a heritage village that serves both local communities and regional visitors. Its historic buildings and unique landscape offer a serene escape, providing a backdrop for enjoying the history, unique retail stores, and world-class cuisine.
Since 2013, the City of Markham has conducted numerous studies to guide the future development of Main Street Unionville. The Main Street Unionville Community Vision Plan (2015) identified various challenges and opportunities, leading to the initiation of the Main Street Unionville Streetscape Master Plan for the Commercial Core in 2018. The preferred streetscape concept received Council approval in March 2022.
Project Updates: Procurement and Construction Updates
In the summer of 2024, the City of Markham awarded the construction assignment for the Main Street Unionville Restoration to CRCE Construction Ltd., with EXP Services Inc. contracted as the project consultant to oversee implementation. This project includes important underground infrastructure improvements, new sidewalks, boulevards, road surfaces, and a new street light system from Hwy 7 to Carlton Road and on East Lane.
The first phase of construction began in August 2024 and was paused in December. Work resumed on February 7, 2025 for the construction and installation of Valve Chamber #2, at the northern extent of the east lane. This work is wrapping up early April.
The second part of construction, focused along Main Street, begins on April 7, 2025 and will continue through December 2025.
Latest Construction Updates
The Main Street Unionville Restoration Project is about to begin its next major phase. Phase 1 of the Project’s Part “B” will begin on April 7th, 2025, after the completion of Valve Chamber #2 (VC2) work. This will include restoration of the sidewalks, boulevards and roadway along Main Street Unionville from its intersection with Carlton Road to in front of 166 Main Street Unionville.
During Phase 1 (April 7 to August 13, 2025), Main Street Unionville will be closed to vehicular traffic to allow the works to be completed. Pedestrian access to businesses, however, will be maintained throughout this period.Map of Road Closures at The Main Street
It is suggested that commuters normally driving through this area, to or from Highway 7 or Kennedy Road, use alternative routes past the construction area.

Why Are We Doing This?
The restoration of Main Street Unionville is crucial for several reasons. The relining of watermains and storm sewers is essential to prevent leaks, blockages, and structural failures, ensuring reliable water and sewer services. Using interlocking brick pavers and maintaining the heritage character of the area is vital to preserving the historic significance of Main Street Unionville. Improved streetscaping, including tree planting and street amenities, will create a more inviting and functional public space for residents and visitors. Additionally, upgrades to street lighting and roadway design will enhance pedestrian and vehicular safety, making the area more accessible and user-friendly.
