That's very important.
In buildings, we should not actually think only in terms of electrification. Building efficiency is extremely important, and we don't have, in Canada, a stock of buildings that are efficient. We should look at deep retrofits for buildings. That cannot happen overnight. It will have to be over 10 years.
We need to increase the rate of deep retrofitting of our buildings, especially to avoid a big jump in electricity consumption. It will be extremely difficult to build the clean electricity infrastructure to supply all our homes if they are electrified.
It is important to, first and foremost, think in terms of a retrofit, which is extremely good for the Canadian construction industry. These are local materials and local workers who will help Canadians to actually live in buildings that are more comfortable. When you have a strong thermal envelope and a well-insulated building, it is more comfortable. That will save everyone money over time because they will then reduce their heating bills, and Canadians are sensitive to these recurring heating bills.
If we do work on the stock of buildings by improving their energy efficiency, then we'll, at the same time, solve some of the problems of increasing electricity production and help Canadians save on energy, which would be good in both aspects.
