A Message From Our Founder

In Fiscal Year 2026 (FY2026), Mattamy stayed the course on sustainability. Across our company, in both Canada and the United States, sustainability remains a deeply held value for our people and an integral part of the way we do business. It is embedded in our ownership and governance structure, management team and operations. Simply put, sustainability is part of everything we do, everywhere we do business. 

Our commitment to sustainability and to reducing our carbon footprint is not swayed by short-term factors or changing opinions. Decades of evidence show that human-caused climate change is real, and we have an ethical obligation to minimize its impact for future generations. Achievements such as building our 1,000th geothermal home and exceeding our greenhouse gas (GHG) reduction targets, along with our other outlined goals, demonstrate that commitment. In addition to recognizing the need to address climate change and other environmental challenges, Mattamy’s understanding of sustainability also encompasses social concerns, including housing attainability and affordability, which is a top priority for our company. 

 

I strongly believe that home ownership benefits people, families, communities and society. That conviction has shaped my life. The dream of home ownership is increasingly out of reach in Canada, the U.S. and other peer countries, especially for young people.

 

Many factors determine a home’s price. Design and construction account for less than one-third of the total cost. Mattamy is doing our part to address what has been called a housing affordability crisis in a way that is achievable and sustainable, including:

 

  • Applying continuous, incremental improvements across home design and construction to improve value. 
  • Establishing a new integrated Product Development team to bring design, engineering and costing together simultaneously to achieve better affordability outcomes. 
  • Rolling out new product lines that are designed to be efficient, attractive and value focused for a wider range of buyers. 

 

Stelumar Advanced Manufacturing Inc. was relaunched in June 2025 to help address the housing crisis by transforming how homes are built. Stelumar will harness automation, robotics and AI to produce modular housing solutions at an unprecedented scale. Off-site, digital production cuts build time and improves consistency. It’s a faster, less costly model. Starting in 2026, Mattamy will be Stelumar’s first customer – and together, we will build homes that are livable, durable, sustainable and affordable. 

 

We continue to share sustainability insights across our industry. Solutions must be fiscally responsible and scalable to avoid limited adoption. This aligns attainability and affordability with sustainability. 

 

In 2023, Mattamy conducted its first materiality assessment to shape our sustainability strategy. In FY2026, we reviewed it to ensure our priorities and performance align with what matters to our stakeholders. While most priorities remained the same, “attainability and affordability” became the top priority – for employees and for customers. 

 

Mattamy was founded in 1978. In May 2026, we reached 150,000 closings, a milestone after almost 50 years in business. Responsibly built, reasonably priced housing gives families pride, security and hope. I look forward to helping position Mattamy to deliver on this promise for the next 50 years.
