I'm going to take things in a different direction, and it's back to Mr. Mueller because we had the pleasure of you appearing before our committee in, I think it was, 2012. You gave some very valuable testimony, and by the way, you spoke to LEED and we have not had LEED here.
What you testified to our committee was that large commercial landlords use pension funds to invest in buildings and the rates of return on those investments exceed 10%. A couple of years ago I met with the realtors association in Ottawa that actually leases the major commercial buildings, and they've shown a much greater demand for the buildings that have retrofitted and gone energy efficient.
Could you speak to this issue? I'm wondering if this is not a huge potential for the Infrastructure Bank. We keep thinking about building freeways, LRT, but given the potential for rate of return on investing in retrofitting commercial buildings, is there not huge opportunity there?
