Yes, the changes to building codes are significant as they move from the national building code into the provincial codes and then, in a few examples across the country, into municipal building codes as well. We looked at the last 10 years of building code updates, and it's hard to track, but we think that there have been over 2,000 individual changes in building codes when you filter through all the local sustainability codes built into that. I want to clarify that these are not core life-safety changes. These are predominantly social policies that have made their way into building codes.
With this cycle of building code updates every few years, it's been rare in the last decade at our organization that we've actually built two buildings under the same set of codes. When we talk about modernizing housing construction, it's really hard to get into a manufacturing mindset when the codes change every project cycle.
