I think they can be classed into three large areas.
One would be around culture and being able to change the culture of wood in Canada and have a greater acceptance of using wood in different applications, especially with the realization that we have new products on the market that offer new solutions. We've supported Wood WORKS!, as have the provinces, to be able to build that culture in Canada as well as emphasize that new products are available.
A secondary one is really around perception. This is overcoming, I think, some of the myths—especially with new engineered wood products—around fire safety, seismic stability, and even, in a second tier of issues, acoustics.
A third issue is really around codes. One of the key things, as I mentioned, was that a change of the building codes to allow six storeys in 2015 has really led to an enormous growth of mid-rise residential construction in Canada. That's why our work, I think, on building codes, while not sexy, is pretty important to the growth of wood construction in Canada.
