B.C. will be ahead of the rest of Canada in allowing 12-storey mass timber buildings, meaning more jobs in manufacturing and in the woods, Premier John Horgan said.
The current building code allows only six-storey mass timber buildings, but the National Building Code is expected to be revised and allow for 12 storeys builds in 2020.

Mass timber construction uses large prefabricated wood units—like the gluelam beams and cross-laminated timbers manufactured by Stucturlam— for wall, floor and roof construction.
Horgan, along with Selina Robinson, Minister of Municipal Affairs and Housing was at Structurlam’s Okanagan Falls at plant to make the announcement Wednesday morning.
“Normally B.C. would assess those recommendations and then they would implement a year or two after that. We believe that the work has been done we’ve got a practical example of more than 12 storeys at Brock Commons of 18, so we’re prepared, we’re confident that the work has been done on safety. The work has been done on the fire stuff,” he said to media and workers at the mass timber plant.
Brock Commons is an 18-storey residence at the University of B.C. campus built in 2016 using mass timber.
“That is the way of the future. We have less volume in the forests and we need more value out of our forests and where better than right here at Structurlam to start that revolution,” Horgan said.
Although B.C. is moving ahead with the increase each municipality will make decisions on if they will allow 12-storey mass timber buildings.
Horgan called the change, “win-win-win,” meaning more jobs in the forestry and manufacturing industries and providing a chance to offset losses of timber due to wildfires over the last few years.
“We’ve had two of the worst fire seasons in our history in 2017/2018 2 million hectares of merchantable timber up in a puff of smoke while in fact smoke that was clogging the lungs of British Columbians, Washingtonians and even Oregonians for the past two summers,” he said. “We have a dwindling fibre basket. We have less wood today than we did 20 years ago, so if we’re going to continue to be a province that depends on forestry, which we will be, we need to make sure we are adding more value not more volume to our production,” he said.
“We can turn those low-cost stands into a high-quality product that will mean more jobs in OK Falls and more jobs in the woods as well.”
Using mass timber construction is also expected to shorten building times and decrease budgets. Horgan said in the Brock Commons project the construction time was cut in half. The building was constructed in just 66 days.
“We have a housing crisis in British Columbia right now and we have a product that can see houses built, mass houses built quickly and in a less impactful way than other forms of construction,” he said.
Horgan noted the hope was exports of the mass timber, specifically in countries prone to earthquakes, will increase.
“The advantage of this on the seismic side is that wood moves. On the earthquake side, wood is a much better product for construction, that’s why we’re excited about the export potential to places like Japan who are already significant purchasers of B.C. wood products. When we show them what we can do with engineered wood products like mass timber products developed here, I think the export potential is significant to areas where seismic activity is concerned,” he said.
