To start with the building sector, yes, in general it's a sector that's of great interest, and it's an area where potentially there are additional emissions reductions that will help to bend that curve.
In terms of standards, a lot of the standards on the building side are done with colleagues at Natural Resources Canada. They have developed model building codes that they then work with the provinces to implement.
As with many things in Canada, the jurisdiction on this is somewhat mixed. Sometimes it's at the provincial level and sometimes it devolves right down to the municipal level. The federal departments and agencies—Canada Mortgage and Housing, for example, and some of the research institutes—work with departments to develop model standards that they then work with our colleagues in other governments to get implemented. It is an area of ongoing and continuing work, and potentially one of the areas that we'll be looking at with other levels of government as we deepen our work on this pan-Canadian framework.
