Thank you.
I have a question for you, Mr. Simpson, but let me preface it by thanking Union Gas for helping the City of Kingston, in my riding, a number of years ago with collecting data on natural gas use for the city's greenhouse gas inventory project. I want to thank Union Gas for being a great corporate citizen in helping out with that.
You talked about your demand side management work and how residential improvements, because of building codes and standards, have resulted in a decrease in use of natural gas. I'm wondering about retrofitting older buildings and whether you would say there's a lot more work to be done, or a lot of progress that you can make, in your demand side management for getting your customers to retrofit their older buildings.
