Old Main Street Infrastructure Upgrades

The Town of Newmarket is conducting infrastructure upgrades in the Old Main Street area (see map below for more information). Significant infrastructure improvements are required on Old Main Street to upgrade the existing water, wastewater, stormwater and road infrastructure to support the community.

The proposed work includes:

• Upgrading the existing water, wastewater and road infrastructure
• Installing new stormwater management infrastructure
• New sidewalks to improve accessibility and safety for pedestrians

Project benefits

Once complete, the Old Main Street area will have new critical infrastructure to support the community, and new storm sewers to prevent flooding, which has been an issue in the past.

The Town of Newmarket is pleased to inform you that a Public Consultation Centre (PCC) will be hosted on Wednesday, November 5, 2025 at the Ray Twinney Recreation Complex – Lounge 2 (100 Eagle Street West) from 6 p.m to 8 p.m. to discuss the Town’s upcoming Infrastructure Upgrades project on Old Main Street (see map below for the study area). At this meeting, staff will provide an overview of the scope of work, impact to your street and construction timelines.

Doors will open at 6 p.m. and residents will have an opportunity to view presentation boards of the construction. The Town will be conducting a brief presentation at 7 p.m. and will have representatives available from the Town Staff and the Consulting Team to answer any questions you may have.
