What Tooketree Passive Homes does

Tooketree Passive Homes is a privately held Canadian prefabricated building panel manufacturer founded in 2018 in Baysville, Ontario, by Melinda Zytaruk (President & CEO) and Rick Zytaruk (CFO & Co-Founder). The company designs and produces SEED (Sustainable, Ecological, Efficient, Durable) Building Systems — CSA-certified insulated structural panels for walls, floors, and roofs engineered to Passive House performance standards. SEED panels use natural biogenic insulation materials (dense-pack cellulose from recycled newspaper, recycled denim batts, recycled wood-fibre board, and sheep's wool) combined with high-performance smart membranes, and are precision-manufactured on CNC machinery at the Baysville facility.

The product portfolio includes SEED Building Panels for new construction up to six storeys (delivering wall R-values above R-50) and SEED Retrofit Panels, developed in partnership with Natural Resources Canada, which wrap existing building exteriors to boost airtightness by up to 96% and insulation value by up to 5x. Tooketree extends its offering through a design partnership with Passive Design Solutions (a catalogue of 60+ pre-designed Passive House plans) and releases all SEED system designs under Creative Commons Attribution-ShareAlike 4.0 licensing to encourage industry adoption.

Commercial activity runs on a B2B sales-led model targeting developers, builders, municipal and federal government agencies, and non-profit housing providers across Ontario, with a secondary direct-to-homeowner channel and a Toronto (North York) office supporting engagement. Revenue is generated primarily through hardware sales of SEED panels and retrofit panels, supplemented by design services and open-source licensing/consulting. The company employs approximately 7 staff, operates at a stated capacity of around 100 units per year (with stated plans to double, then triple that capacity on-site), and prices its enclosure at a 10-15% premium over minimum code-built construction — a premium documented to be recovered in approximately five years through 80-90% reductions in heating and cooling energy costs. Tooketree is a CHBA Net-Zero Qualified Builder, its leaders are Phius Certified Passive House Builders, and the company has won the 2024 Ontario Embodied Carbon Awards Innovation in Industry Award and a Foresight 50 cleantech recognition.

Core offering

Tooketree Passive Homes manufactures and sells SEED Building Panels—prefabricated, CSA-certified, Passive House-grade insulated structural panels for walls, floors, and roofs—made with natural biogenic materials including dense-pack cellulose, recycled denim, recycled wood fibre, and sheep's wool. The company also sells SEED Retrofit Panels for existing building envelope upgrades, and offers building design services through a partnership with Passive Design Solutions. All panels are precision-built using CNC machinery in the company's Baysville, Ontario factory and engineered for buildings up to six storeys.

Product overview

Tooketree Passive Homes operates as a prefabricated building panel manufacturer offering a unified system called SEED (Sustainable, Ecologically-responsible, Efficient, Durable) Building Systems. The core product line consists of SEED Building Panels (wall, floor, and roof panels) for new construction and SEED Retrofit Panels for existing building upgrades. Both panel types feature CSA-certified components, natural carbon-sequestering insulation materials (primarily dense-packed cellulose), and are engineered to Passive House performance standards with R-values exceeding R50 for walls. The company also provides building design services through partnership with Passive Design Solutions, offering over 60 pre-designed plans compatible with SEED panels. All panels are manufactured in Tooketree's Baysville, Ontario factory using Canadian materials including Ontario Wood, Quebec woodfibre board, and German-engineered vapour barriers. Installation can be completed in days, resulting in sealed, insulated building envelopes ready for rough-ins and cladding.
