I'll just add, very quickly, that I agree that the building stock is particularly important. Certainly, the code is related to new buildings. Given the long-lived potential of all the buildings once constructed, applying the logic of “when you're in a hole, step one is to stop digging,” we can start building buildings that are much more energy efficient. Those technologies exists. That ability exists. It's really just a matter of mainstreaming their application. That's something that I'm quite optimistic about.
In terms of generating longer-term emission reductions, they won't generate significant emission reductions prior to 2030, but have considerable potential to drive deeper reductions in the longer term.
We're trying this collection of policies through the pan-Canadian framework. We've tried to focus both on things that can drive near-term reduction and on things like building codes, equipment standards and other things that can provide deeper reductions in the longer term.
