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 Status (as of December 2025)

Main Street Unionville has reopened to vehicle and pedestrian traffic between Carlton Road and south of the railway tracks as of December 23, 2025.

Major construction under Phase 3 is now complete. The project is transitioning into close-out activities, which include final electrical connections, minor restorations, and landscape-related works. These remaining items do not require road closures and will continue into Spring 2026 as weather and coordination allow.

Thank You to the Community

The City would like to sincerely thank the Main Street Unionville community, especially local businesses, residents, and property owners, for their patience, resilience, and cooperation throughout construction.

This project was complex and, at times, disruptive. We recognize that access challenges, noise, and construction impacts were not easy, particularly for businesses that continued operating while work was underway. Your understanding and willingness to work through these challenges played a critical role in allowing the project to move forward safely and efficiently.

We appreciate the collaboration, feedback, and support shown throughout this journey and look forward to welcoming everyone back to a revitalized Main Street Unionville.

What’s Been Completed

The Main Street Unionville Reconstruction Project has delivered the following improvements:

• Full reconstruction of the roadway, sidewalks, and boulevards
• New interlocking pavers and streetscape features
• Underground infrastructure upgrades, including watermain and storm servicing
• New lighting, street furniture, and accessibility improvements
• Restoration and reopening of all construction phases (Phases 1, 2, 3, and 4)

Upcoming Work (2026) - Remaining and Upcoming Work

While Main Street is fully open, a limited number of activities remain:

• Final electrical tie-ins and coordination with Alectra
• Removal of temporary or redundant lighting infrastructure
• Minor boulevard and landscaping restoration
• Final surface clean-up and deficiency corrections
• Victoria Avenue resurfacing (timing to be confirmed)

Updates will be shared if any of this work impacts access or operations.

Parking & Access

On-street parking and pedestrian access along Main Street Unionville have been instated following reopening. Some short-term parking adjustments may continue to be reviewed as part of the final streetscape configuration.

Businesses and residents will be notified in advance if any temporary parking or access changes are required during remaining close-out work.

Project History and Overview

The Main Street Unionville Reconstruction Project was delivered in four phases:

• Phase 1: Carlton Road to 166 Main Street Unionville
• Phase 2: 166 Main Street Unionville to Fred Varley
• Phase 3: Fred Varley Drove to Railway Tracks
• Phase 4: Railway Tracks to Hwy 7

Construction was sequenced to maintain access to businesses and properties while upgrading aging infrastructure and enhancing the public realm. All four phases are now complete.

Proposed Phase Plan

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.
