There are various studies that are done that rank different countries. I think Canada is somewhere in the middle of the pack, but I wouldn't want to try to quote a specific study.
There are things that Canada can do from a policy perspective. One of the things that the federal government can do is lead on building codes and standards around high performance homes and buildings.
On the residential side, passive house technology is a technology that I believe originated in Saskatchewan. It became very popular and common in Germany. It's a whole home envelope that's very tight with very low energy usage. In Germany.... You can find videos on YouTube of these homes being heated by hair dryers. They are very common.
One of the things government can do is lead on trying to advance standards like the passive house. Net zero home is also a leading standard that government can play a role in pushing forward. There are lots of opportunities.
