It can be by introducing better materials that are suited for the Canadian environment.
I find that composites excel in many areas. Because they are inorganic, there are no worries about anything rotting on you. Their weight-to-strength ratios are off the charts. If you have a green thumb and you want to think about anything sustainable, you are building with 100% recycled PET. All of the global companies put together are using 0.007% of it right now, so there's room for many companies like mine that want to use that material.
It has obviously proven its point commercially on the water. In a static environment like a home, it can become multi-generational very quickly, with low maintenance, and it can give you all the energy efficiencies you could care to mention.
