I feel that my colleagues from the Canadian Wood Council would be better able to give you an answer on that, because they take care of the interface with the national building code.
We provide the information needed for wood to be recognized for use in 10- or 12-storey buildings. We work in co-operation with the National Research Council of Canada on structures and on fires, and we provide the arguments to support the performance of the buildings.
So, as for the code, I feel that my colleagues from the Canadian Wood Council would be better able to answer your question.
