Absolutely. As Vincent said, the low-carbon economy fund was provided to those provinces and territories that submitted proposals, many of which were in the residential, commercial, and institutional energy efficiency retrofits base, so those are the incentives.
With respect to model codes for existing buildings, the process is just beginning at this stage. In terms of what we found, there are examples such as equipment. For gas furnaces over time, the cost of furnaces actually decreased by 30% between 2000 and 2010, so through innovation and demonstration projects those costs are going to come down. We're also obviously working very closely with industry to build capacity in that regard, but ultimately it is up to the provinces and the territories to determine how homes and buildings are constructed in their respective jurisdictions.
