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 along the east lane 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 was completed in April 2025.

The second part of construction (Part B) began on April 7, 2025 and is focused on the restoration of Main Street Unionville. The work will be undertaken in phases as it moves toward Highway 7. The last phase of the project is expected to be complete in December 2025.

Latest Construction Updates

Phase 1 of the Main Street Unionville Restoration Project’s “Part B” is well underway. Since April 7th, 2025, CRCE’s construction crew has been busy with the 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 mid-August 2025), Main Street Unionville will be closed to vehicular traffic to allow the works to be completed. Pedestrian access to businesses, however, is being 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.

During construction, businesses remain open, and parking is available in the 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.
