George Brown College has steadily grown since its establishment in 1967 and now operates out of more than a dozen buildings spread throughout Toronto’s core….The public college of 26,000 students plans to erect a 12-storey tower framed of wood at its waterfront campus on Lake Ontario to house its computer technology program and a centre for researching climate-friendly building practices.  …Once ready in 2024, the tower dubbed The Arbour will be the highest wood-framed building for institutional use in Ontario and a significant milestone in the revival of timber as a construction material for tall structures. “The future is certainly wood,” says Shane Williamson, a principal at the architecture firm Williamson Williamson Inc. in Toronto. …The revival may gain even more momentum under a new federal government program announced this fall.
