The University of Toronto’s motto “velut arbor aevo,” meaning “may it grow as a tree through the ages,” is coming to life with the construction of a tower made primarily of mass timber. Construction is planned to begin this spring on a 14-storey, 80-metre-tall academic building that will be built on a frame made of wood instead of steel. To date, it’s the largest tall mass timber structure of its kind to go up in North America. …The Canadian Wood Council says mass timber is dense, strong and efficient to build with… Chief executive Kevin McKinley says. …The university’s tower is also important because it supports the efforts of Canada’s forestry sector to find new markets for its products and stay at the forefront of technology innovation. “There are also the intangible benefits. …It’s nice to live or work in a building made of wood”.
