I forgot, Chair, that I'm actually sharing my time with my colleague, but I have just one really quick question to Mr. Marks.
You talked about the challenges that occur with modifications. Can you just help me understand? Is there a particular, greater challenge to modifications that exist now in existing structures? In existing structures now, the same modifications take place, and we know they're not made out of wood. Aren't those risks already present? Doesn't the suite of regulations and obligations around building codes and what people have to comply with already exist, and how would it differ from wood for a structure that, if safe when constructed and all the rest, would change?
