Why Sustainable Forestry Matters in Mass Timber Construction
Forests are essential to sustaining life on our planet. They play a critical role in regulating climate,
purifying air and water, and supporting biodiversity across ecosystems.
Just as importantly, forests provide a renewable source of wood a cornerstone material
for sustainable construction and mass timber buildings.
At Cornerstone Timberframes, we design and build a wide range of wood structures
from screen rooms, custom homes, and cottages to
multi-storey commercial and institutional mass timber buildings.
Healthy, responsibly managed forests are the foundation of everything we do.
When forests thrive, our work thrives too supporting skilled jobs,
reliable supply chains, and the creation of
durable, beautiful, and low-carbon buildings.
When forests are damaged or depleted, the wellbeing of everyone in our construction ecosystem is at risk.
That’s why sustainability is not a marketing claim for us – it’s a responsibility.
This commitment is why Cornerstone Timberframes is FSC® certified.

What Is FSC® and Why It Matters
The Forest Stewardship Council® (FSC) is the world’s most trusted forest certification system.
Unlike other forestry programs, FSC is a fully democratic organization with balanced representation from three equal chambers:
- People and communities whose livelihoods depend on forests
- Businesses and organizations that rely on forest products
- Scientists and environmental groups dedicated to protecting forest ecosystems
Every three years, FSC members meet at a General Assembly to elect leadership and vote on policies.
This governance model ensures FSC standards are
science-based, socially responsible, and economically viable.
FSC is independent of industry lobbying and financial influence,
allowing it to act solely in the best interests of forests and future generations.
Its mission – “Ensuring forests for all, forever” is upheld through five core principles:
- Zero deforestation preventing conversion of forests to non-forest use
- Protection of ancient and endangered forests
- Fair wages, safe working conditions across forestry and wood products industries
- Preservation of biodiversity and natural habitats
- Respect for community and First Nations rights

FSC Chain-of-Custody Certification at Cornerstone Timberframes
To become an FSC® Chain-of-Custody certified company,
Cornerstone Timberframes completed a comprehensive third-party audit.
This process included:
- Inspection of our fabrication facility and timber yard
- Review of labour practices, safety programs, and employee training
- Verification of purchasing, inventory, and material tracking systems
- Documentation ensuring FSC timber is properly identified and handled at every stage
Maintaining FSC certification requires continuous training, strict documentation,
and full traceability from sustainably managed forests to finished
mass timber, glulam, and CLT structures.
Among all forestry certification systems, FSC is widely regarded as the most credible and impactful.
For architects, developers, and builders focused on sustainability, specifying FSC-certified timber
is one of the most effective ways to reduce environmental impact while maintaining performance and beauty.
Specify FSC® timber for your next project and build with confidence in both structure and stewardship.
