Thank you very much, Mr. Chair.
I want to thank all the witnesses. Your statements were very informative.
Mr. Bradley, I'd like to start with you.
Yesterday, in Sydney, Nova Scotia, your president said that it would take $350 billion, if I'm not mistaken, over the next 20 years to renew existing infrastructure. That's a huge amount, but it lines up with other figures we have seen when it comes to other aspects, such as physical infrastructure.
What kind of a renewal are we talking about? When you get into a smart grid and all the high-tech advancements that entails, especially with respect to renewable energy, how much has to be invested over the next 20 or 30 years?
