I believe the national building code changes on a five-year cycle, and then the provincial codes follow that. We have a nuance in British Columbia, in which there's a provincial energy step code by which every municipality gets to choose which step they adopt and when they adopt it. Just for our business that focuses on the Lower Mainland, there are 21 different versions of that stack of codes to build housing today. You can imagine the inefficiency this creates.
As I said, we've done the work. We have looked at buildings that we built over the last 10 years. Twice, we have built buildings under the same set of codes.
