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 fall 2022 subject to contractor progress.

What to Expect

  • Construction will take place Monday to Friday, from 7 a.m. to 5 p.m. Please note that on occasion, contractors will be required to work past 5 p.m. and on weekends as permitted by The Noise Bylaw (Chapter 591, City of Toronto Municipal Code).
  • Street occupation permits for lane closures on Front and Jarvis Streets, adjacent to the site, will be obtained by the Contractor as needed for loading purposes during construction.
  • 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.

Work completed until the end of June 2021 includes:

  • Parking garage concrete structure completed
  • Parking garage elevator and stair cores completed
  • Mechanical and electrical rough-ins nearing completion
  • Ground floor tapered concrete columns underway (12 of 32 completed)

Ongoing work over the summer will include:

  • Steel superstructure construction to commence in July 2021
  • Glass curtain wall fabrication underway and will be installed in sequence with the steel superstructure construction
  • Continuation of below-grade building mechanical and electrical services
  • Continuing installation of elevator and stair cores above grade

Revised Timeline:

The Contractor has advised of disruptions to material and equipment supply chains due to COVID-19. This, combined with added safety protocols for workers has caused a productivity loss on-site, resulting in a delay in completion from Spring 2022 to Fall 2022.
