The Stock Exchange Tower (Tour de la Bourse), a cornerstone of Montreal’s International District, is entering the final phase of its three-year revitalization plan (2023–2026).

Driven by Groupe Mach, this imposing 47-story concrete landmark is reinventing itself.

By balancing the modernization of critical infrastructure with the integration of innovation hubs like ÉTS’s Espace Génie, the project aims to prove that a heritage building can outperform "new" towers by combining historic character with cutting-edge energy efficiency.

Project Timeline

2026: Major Restructuring

Estimated Budget

Global Modernization: $50M to $75M (estimated for the 2023–26 phase)

 

Project Details and Modernization

The 2026 construction site goes beyond simple code compliance; it is a full-scale restructuring of the asset's value:

  • Envelope and Structure: Meticulous restoration of the iconic columns and resealing of the facades to improve thermal airtightness.

  • HVAC Systems: Transitioning to intelligent energy management systems, targeting a 25% to 30% reduction in electricity consumption.

  • Tenant Experience: A complete overhaul of signage, a modernized main lobby designed by Saucier+Perrotte, and improved direct access to Montreal’s Underground City (RESO) and the Square-Victoria–OACI metro station.

 

Tenant Ecosystem: Stability and Innovation

Groupe Mach’s retention strategy relies on a strategic blend of financial pillars and new technological players.


The Historic Anchor: The Montreal Exchange (TMX Group) remains the prestige tenant, occupying the lower floors and the historic trading floors.

 

With over 1 million square feet of space, it is difficult to provide a fixed number of tenants, as the figure fluctuates constantly with new leases and subleases.


However, according to 2026 market data and real estate directories, Place Victoria is estimated to house between 60 and 80 distinct tenants.

 

1. Anchor Tenants (Large Floorplates)

These institutions often occupy multiple full floors and represent the majority of the leased area:

  • TMX Group (Montreal Exchange): The flagship tenant occupying the base of the tower and technical floors.

  • Fasken Martineau DuMoulin: One of Canada’s largest law firms, occupying a significant portion of the upper floors.

  • Autorité des marchés financiers (AMF): A major institutional presence tied to the building’s financial vocation.

  • RBC Capital Markets: A pillar of the banking sector present in the tower.

 

2. Institutional and Public Tenants

  • ICAO (International Civil Aviation Organization): While headquartered in its own adjacent building, the organization and its delegations frequently use satellite or service spaces within the tower.

  • ÉTS (École de technologie supérieure): With its "Espace Génie," the university occupies strategic innovation spaces, attracting a steady flow of researchers and students.

 

3. SMEs and Professional Services

The tower hosts a multitude of tenants occupying spaces ranging from 2,000 to 10,000 square feet:

  • Financial services and wealth management firms.

  • Consulates and foreign trade representations.

  • High-tech firms and consulting services.

  • Retail services on the ground floor and tunnel levels (restaurants, boutiques, postal services).

 

4. 2026 Leasing Dynamics

With an occupancy rate holding steady at around 85%, the tower currently has a few vacancies (approximately 150,000 sq. ft. available in blocks), particularly on floors targeted by current mechanical renovations. These upgrades are specifically designed to attract new players who prioritize environmental certifications.

 

5. New Arrivals & Expansion

  • ÉTS (Espace Génie): A new university innovation and incubation hub occupying the former Exchange floor, bridging the gap between academia and business.

  • Fasken Martineau DuMoulin: The law firm maintains a massive presence, benefiting from modernized conference facilities.

  • ICAO & AMF: The Financial Markets Authority and international bodies continue to stabilize the occupancy mix.

  • Construction Impact: Work is being carried out in phases to minimize noise, allowing professional firms to maintain operations without major interruption.

 

Social and Financial Impact

  • Capital Retention: By modernizing 800 Square-Victoria, the developer prevents the flight of major tenants to new downtown towers, thereby stabilizing property values in the International District.

  • Public Square Revitalization: The interaction between the tower and Victoria Square breathes life back into a public space often perceived as purely transactional.

  • Fighting Urban Sprawl: Maintaining high-quality office density directly above a major transit hub remains the best defense against urban sprawl.
