That's an important question. In the world of real estate construction in Canada, there are many small players, entrepreneurs, who typically build a few hundred houses. The market is therefore very fragmented when it comes to production, which is why it's important to develop training and tools, as well as share best practices within the sector. There are initiatives, such as the Local Energy Efficiency Partnerships, or LEEP—which I will not have the opportunity to discuss in detail here—specifically seeking to work with the builders in a particular region to ensure that they are all together, that their staff receive training and that best practices are shared, as you have suggested.
