I had the good luck to be at COP26 and COP27 with the Canadian delegation, where I saw different materials proposed for housing. The question we asked was, how was it tested? This is something that is always really important. How do we get from this proposition of a new material to getting it onto the work site?
For asbestos, it got in really quickly. Quebec is the only province where we used it in concrete, and we used it everywhere. Across all public services, we have this material that is just lying there where the public can be infected, and workers can be affected by it too. What we need to do is have a material thoroughly tested beforehand. We have all the resources for this, but sometimes we let materials onto the work site too quickly.
