The new Ontario Secondary School Teachers’ Federation (OSSTF/FEESO) Headquarters and Multi-Tenant Commercial Building, designed by Moriyama Teshima Architects has officially opened, overlooking the Don Valley ravine in Toronto, Ontario.

OSSTF is a mass timber facility that ensures that the OSSTF Headquarters and Multi-Tenant Commercial Building operates as a hub that supports public education in Ontario, provides healthy workplace environments for its staff and visitors, and meets the organization’s goals of financial resiliency.

The three-storey, mass timber, 127,000-square-foot facility is centred on the OSSTF Headquarters. Built of cross laminated timber (CLT) floor slabs and glue laminated timber (GLT) beams and columns, structural components have been sourced nationally where possible.

“The central atrium is the building’s key design feature where everyone in the building can connect to each other and connect to nature, ultimately making for a healthier working environment for all who visit and work here,” said Carol Phillips, partner, Moriyama Teshima Architects.
