The North St. Lawrence Market Redevelopment project is taking place in three phases. The project is currently in Phase 3, construction of the new North Market Building.
On May 15, 2019, City Council approved the awarding of a contract for the construction of the new St. Lawrence Market North building at 92 Front St. to The Buttcon Limited/The Atlas Corporation Joint Venture. Construction of the new market began in July 2019. The building is expected to be completed and operational by spring 2022 subject to contractor progress.
Excavators will be used throughout the excavation work including one with a hydraulic hammer to break up existing foundations.
Concrete trucks will be on site during construction along with a tower crane to provide handling access for materials and equipment.
There will be construction related noise and vibration while construction is taking place. Vibration may be experienced at adjacent buildings and structures.
