Thank you very much to the witnesses for their testimony. It's very interesting.
The first question is for Mr. Gordon.
Talking again about the regulations and affordability, I'm from the Vancouver area. The regulations add about $600,000 to the cost of the average house in Vancouver, which is a lot.
You mentioned the housing envelope and how we're becoming more and more efficient, but that's forcing people to go into forced air climate and into air conditioning. For most of our history in the Lower Mainland, most houses haven't had air conditioning, but now we're being forced into that. You've touched on this quite a bit. Also, it's interesting, because forced air takes energy, so you're using more energy. It seems to be kind of.... We're trying to reduce consumption, yet we don't seem to be working in tandem, one hand with the other.
I want to ask you to further elaborate on this and on the cost benefit to what is being done, and elaborate heavily on the cost, because people are finding it very challenging in many parts, especially our urban centres like the Lower Mainland, Toronto and other places, to be able to afford housing.
Are we really hurting ourselves by what we're doing? When is it enough?
