Crémazie Building LEED Gold Certified


The Société de transport de Montréal (STM) is proud to announce that its new Crémazie building, located at the corner of Crémazie and Saint-Laurent, has received the Canada Green Building Council’s Gold LEED certification for new buildings (LEED NC).

“The STM is committed to doing our part for sustainable development in Montréal,” says André Porlier, Director of Strategic Planning, Corporate Secretariat, and Social Responsibility for the STM. “That’s why we factor environmental, social, and economic considerations into every aspect of our operations and processes, including by building and operating sustainable, resilient infrastructure. It is with great pride that we accept this certification as further proof of our commitment to making sustainable development a priority.”

The STM applies for LEED Gold certification for major new surface‑level builds because of the many benefits of sustainable design. This is the second STM project to receive LEED‑NC Gold certification.

The Crémazie building’s sustainable features – some of which contributed to the certification - include:

Energy efficiency

  • Efficiency measures and a heat recovery system to reduce energy consumption by 48% compared to conventional designs


  • White and green roofs to reduce the heat island effect
  • Workspaces with abundant natural light and meeting rooms set around an atrium
  • Common areas for employees, including a well‑lit cafeteria and a patio

Resource consumption

  • Low‑flow equipment and a recovered-rainwater toilet‑flush system to reduce water consumption by 55%
  • Built with 26% recycled and 47% regionally sourced materials
  • Over 75% of construction, renovation and demolition waste diverted from landfills
  • Waste management plan in place
  • Part of original brickwork from the old building incorporated into the turret of the main entrance

Sustainable mobility

  • Extra parking spaces reserved for carpoolers
  • Charging stations for electric service vehicles
  • Indoor bicycle parking

The 41,000-square‑metre building has been in operation since 2022 and includes a major bus maintenance facility, a centralized distribution centre, a training facility with an Azur métro car simulator, and the bus engineering and operational planning departments. The work to replace the old facility—a plant dating back to 1948—began in 2017.
