That's a fantastic question. I want to refer you to a wonderful study that was done—I think Mr. Whalen referred to it earlier—by the Canada Green Building Council. They assessed specifically where the opportunities are for retrofits in the country to reduce our greenhouse gas emissions. They did a study where they analyzed the consumption per province—how much consumption there is in all the buildings in each of the provinces—but then also what the GHG impacts are for each of those.
Their recommendation was based on this very visual graph that shows right away that there are definitely provinces that have significantly higher GHG impacts. Maybe that could be a really good place to begin, starting to make these retrofits and to invest in renewable energy. In provinces where there's already a very low GHG emission—as with Quebec, Ontario, Alberta, Manitoba, and B.C., thanks to hydro—the government could focus on other aspects of retrofit that can also help buildings consume less.
Definitely, yes, you should focus on the largest emitters first.
