Ontario’s tallest residential mass timber building is nearing completion in Etobicoke, introducing a new model for sustainable urban housing. Constructed using prefabricated wood panels shipped from the West Coast and powered by geothermal energy, the nine-storey, 60-unit development demonstrates how engineered timber and industrialized construction methods can reduce emissions while accelerating building timelines. Enabled by updated provincial building codes allowing taller timber structures, the project highlights how prefabrication and low-carbon materials may help address both climate goals and housing shortages.
February 13th 2026 - Ontario is preparing to welcome a landmark in sustainable architecture as the province’s tallest residential mass timber building approaches completion. The nine-storey development will soon open its doors to residents, delivering 60 apartments constructed largely without emissions-intensive concrete — a significant milestone in Canada’s evolving approach to low-carbon housing.
Instead of relying on conventional structural systems dominated by steel and poured concrete, the building is framed and enclosed primarily with engineered wood. The result is a structure that not only reduces environmental impact during construction but also demonstrates how modern housing can align with climate goals without sacrificing performance or comfort.
Wood Panels Built Across the Country
The project, located in Etobicoke and known as Hälsa, was assembled using large prefabricated timber panels manufactured on Canada’s West Coast. These panels arrived on site nearly complete — pre-installed with windows, exterior cladding, and structural components — allowing construction teams to focus on assembly rather than traditional ground-up fabrication.
Once delivered, cranes lifted the prefabricated sections into place, attaching them to a structural frame also built from timber. This approach significantly reduced on-site labour complexity and minimized construction waste, illustrating how industrialized building methods are reshaping residential development.
In 2024, Ontario updated its building code to permit mass timber buildings up to 18 storeys tall, effectively opening a new market for taller wood structures. The policy shift signals growing recognition that engineered timber can play a major role in addressing both housing shortages and climate challenges.
Prefabrication as the Key to Efficiency
According to project leaders, prefabrication is central to making mass timber construction economically viable. Rather than building every component on site — a process vulnerable to delays and inefficiencies — factory manufacturing allows for precision production under controlled conditions.
The timber panels used in Hälsa were prepared by a British Columbia technology company specializing in automated manufacturing. By integrating robotics and digital modeling, the company produced building components ready for rapid installation upon arrival.
This streamlined process could shorten construction timelines by three to four months compared to traditional concrete construction. Faster delivery is increasingly important as Canada seeks to dramatically expand housing supply in the coming decade.
Balancing Sustainability and Cost
Despite the environmental advantages, developers emphasized the importance of maintaining competitive construction costs. Sustainable buildings, they argue, must remain financially accessible to gain widespread adoption.
While Hälsa ultimately cost slightly more than a comparable cast-in-place concrete structure — only a few percentage points higher — the project serves as a prototype for future developments. Repeating similar prefabricated designs at scale could reduce expenses over time while accelerating delivery.
The long-term ambition is clear: create replicable building systems that can be constructed faster, more efficiently, and with significantly lower environmental impact.
Mass Timber and Canada’s Housing Future
The timing of the project aligns with national housing ambitions. Canada has set aggressive targets to increase residential construction, with federal leadership emphasizing the need to rethink how homes are built. Prefabrication and modular construction are increasingly viewed as essential tools for achieving higher production volumes without compromising quality.
Mass timber offers a compelling alternative to carbon-intensive materials such as concrete and steel. Engineered wood stores carbon absorbed during tree growth, reducing embodied emissions associated with construction. At the same time, modern timber systems meet — and often exceed — strict fire safety and structural performance standards.
Experts caution, however, that sustainable forestry practices remain essential to ensure environmental benefits are fully realized.
Meeting Green Building Standards
Hälsa achieves Tier Two certification under the Toronto Green Standard, exceeding the mandatory sustainability baseline required for new developments. The framework evaluates projects based on energy performance, emissions reductions, and environmental resilience.
Even amid provincial legislation affecting municipal green building policies, Toronto continues to enforce climate-focused performance targets for new construction, reinforcing the city’s commitment to low-carbon development.
The Role of Local Manufacturing
One of the project’s biggest challenges was logistics. Transporting massive prefabricated panels across multiple provinces introduced scheduling complexities and delays, underscoring the need for regional manufacturing capacity.
The timber manufacturer behind Hälsa is now planning to expand operations into Ontario, with a proposed factory expected to open later this decade. Establishing local production could dramatically improve efficiency, reduce transportation emissions, and accelerate adoption of mass timber construction throughout the province.
Industry leaders describe the situation as a classic “chicken-and-egg” challenge: developers need local factories to scale projects efficiently, while manufacturers require proven demand before investing in new facilities.
Reducing Both Embodied and Operational Carbon
The environmental strategy behind Hälsa extends beyond construction materials. While timber reduces embodied carbon — emissions generated during manufacturing and building — the project also tackles operational emissions through renewable energy systems.
Twelve geothermal wells drilled approximately 600 feet underground provide heating and cooling for the building. This system stabilizes indoor temperatures using the earth’s natural thermal energy, significantly lowering long-term energy consumption compared to conventional HVAC systems.
Only a small number of structural elements, including the elevator shaft, rely on concrete, demonstrating how hybrid systems can balance practicality with sustainability goals.
A Growing Movement Across Canada
Mass timber construction has already gained momentum on Canada’s West Coast, where several tall wood buildings have proven the feasibility of large-scale timber architecture. Ontario is now rapidly catching up, with multiple academic and residential projects embracing engineered wood.
Developers behind Hälsa have pursued a project of this type for more than a decade, waiting for building codes, manufacturing capabilities, and market readiness to align. The collaboration between forward-thinking developers and Canadian manufacturers ultimately made the project possible.
The Future of Tall Timber Living
As cities confront the dual pressures of housing demand and climate responsibility, projects like Hälsa suggest a new direction for urban development. Prefabricated timber construction offers faster timelines, lower emissions, and adaptable design systems capable of scaling to meet future needs.
What was once considered experimental is quickly becoming practical. With supportive policy, expanding manufacturing infrastructure, and growing public acceptance, mass timber buildings may soon become a defining feature of Canada’s residential landscape — proof that sustainability and livability can rise together, floor by floor.
