A final question, Mr. Chairman.
With respect to a framework of support measures, Mr. Shields, you mentioned the support measures that would finance on-site renewable energy regeneration. Has any approach been taken, from your perspective, with respect to multiple-occupied buildings that are clustered together and the strategic capacity to achieve on-site renewable systems in those very, very large residential complexes? Has any work been done on that, asking CMHC, for example, as part of that overall strategy, where huge, huge impacts could be made? Has there been any work done in that area?
